Japan Theme Parks With Kids 2026: USJ vs Tokyo Disney vs Legoland

Start here: with kids, the wrong park is worse than staying home

I spent that afternoon crouched at the USJ entrance wiping my younger one's tears. She was 5 cm short of the height line, the 90 minutes we had just spent in the Mario line ended at a sign telling us she could not ride, it was 34°C outside and our water bottle had been empty for an hour. She was 4 years old at the time and her brother was 7. I have taken the two of them through Universal Studios Japan, Tokyo Disney and Nagoya Legoland, and two full meltdowns on site bought me one conclusion: pick the wrong park and the trip is worse than not going at all.

On that first Universal visit she was 4, too short for most of the rides, in tears by the end of a 90-minute Mario line, and close enough to heatstroke in the summer sun that I nearly cried along with her. We took her to Legoland instead the following year and she spent 6 hours in the brick-building area and refused to leave. Same kid, different park, and the face she made was unrecognizable.

So this piece answers one question: how old is your kid, can they physically ride, and can they stand in a line? Get those three straight and the park choice makes itself.

July update: two anniversaries land on the same summer, One Piece at USJ and DisneySea's 25th

Honestly, this section was not supposed to exist. I finished rewriting the summer part at the end of June and thought I was done, then in mid-July I went looking for Mario timed-entry tickets for my older one and found the USJ homepage had turned into One Piece wall to wall. The announcement was dated 4/24, which means I had missed it for nearly three months. So I came back and wrote this in, because it changes which park you should pick this summer and what time of day you should walk in.

One Piece Premier Summer 2026 at USJ: opens 7/30, runs through 11/19

USJ announced on 4/24 that the summer headliner of its 25th-anniversary run is One Piece, from 7/30 through 11/19, with three pieces to it:

1. One Piece Premier Show 2026: a live outdoor evening show, 84 performances across the whole run, at most 1 per day, doors at 18:15, curtain at 18:45, about 80 minutes long. Boa Hancock returns after 12 years away, and the One Piece fans in the parent seats will be more worked up than the kids.
2. Sanji's Pirates Restaurant is a themed dining show where the meal and the performance happen at once, which is the easiest possible format with kids in tow.
3. One Piece × Story Ride: a boat-shaped coaster set on Elbaf, flying along with the Straw Hat crew.

Cold water from the parenting side first. The Premier Show starts at 18:45 and runs past 8:00 pm. My younger one is 5 years old now and needs to be horizontal by 9:00 pm, so a show like that puts us back at a city hotel well after 10:00. A night event is a bonus for kids 8 years old and up and a penalty for anyone preschool age, so do not let the franchise cloud the call. The seats are reserved and cost extra, general sale opened on 6/10, and summer weekend slots are moving quickly, so buy in advance if you know you want it instead of deciding at the gate.

Tokyo DisneySea turns 25: the party started 4/15, the actual birthday is 9/4

I left this out of the January version because I had told myself that DisneySea opened on 2001/9/4, so a 25th anniversary could only be a September thing. Reading Oriental Land's 4/28 press release showed me I had it backwards. The anniversary program, Sparkling Jubilee, started on 2026/4/15 and runs all the way to 2027/3/31, and the 9/4 opening date is simply the peak of a year-long celebration. Go to DisneySea this summer and you are already inside the 25th-anniversary window.

Two practical consequences for families:

• The upside: the anniversary shows, merchandise and menu items are running this summer already, so there is nothing to wait for until September.
• The cost: DisneySea skews toward 6 and up as it is, and the anniversary pushes attendance higher, so more weekend days will run close to the 90,000 people the park can hold. With a kid under 5, my line has not changed: pick Land over Sea, however good the anniversary smells.

One sentence for the whole summer: 8-year-olds and up go to USJ for the One Piece and 25th-anniversary double bill, 3- to 7-year-olds go to Disneyland and pick up the Sea anniversary mood from across the resort, 2- to 5-year-olds stay with Legoland and skip every crowd. The age split has not moved since January. What has moved is the bonus each park throws in for going right now.

Universal Studios Japan: heaven for thrill-seekers and franchise fans

Who it is for

• Kids 8 years old and up, at least 122 cm tall.
• Fans of Mario, Harry Potter, the Minions and Demon Slayer.
• Anyone who likes intense rides and is willing to try a vertical-drop coaster.
• Not a great fit: kids under 4 years old, who can ride almost nothing.

What to ride in summer 2026

1. Super Nintendo World: Mario Kart is the busiest attraction in the park, 120-180 minutes in summer. Skip-the-line here is a necessary purchase
2. The Wizarding World of Harry Potter: the 4D flight through Hogwarts castle gets adults screaming too
3. Minion Park: relatively friendly for younger kids, with shorter lines
4. Neon Glow Up: the 25th-anniversary night event, 7/1 to 8/26, with the whole park lit in neon after dusk, which conveniently takes over the hottest stretch of the day

The headline for summer 2026: USJ's 25th, Discover U!!!

Before you settle on a summer park, this one has to go first. 2026 is USJ's 25th year open, the official theme is Discover U!!!, it runs from 3/4 to 3/30 the following year, and going this summer drops you into the hottest stretch of the whole celebration. Three things to hold on to if you are bringing kids:

• Neon Glow Up, 7/1 to 8/26: night only. My older one spent last year's daylight hours wearing a face like thunder, so this year I plan to put the big rides in the morning and save the evening for the neon, which makes his mood far easier to manage.
• Super Nintendo World also turns 5: in peak season you need a timed-entry ticket or an assigned window to get in at all, and that single fact dictates the shape of your day. I cover how to get one in the ticket section below.
• Cool Japan 2026: Frieren and Jujutsu Kaisen take turns, but each has its own dates (the Detective Conan run already closed on 6/30, so you cannot see it now). If a specific franchise is the whole reason you are going, check the dates first. The One Piece run that takes over from 7/30 is broken down in the double-anniversary section above.

This piece is written from the three-parks-by-age angle. If USJ is already decided and you want the full 25th-anniversary lineup plus the per-minute break-even math on tickets, I wrote a separate piece on exactly that: Is USJ's 25th anniversary worth the trip right now? The lineup and the ticket break-even math.

The cheapest way to buy tickets

How to buy	What you get	Why it works
Klook USJ QR code e-ticket	Officially licensed, usable the moment you buy	Stack a 1stCoupon code for a little more off
KKday officially licensed USJ ticket	Ticket and Express Pass bundles	Limited-time codes show up now and then
Official site	Priced in yen	You can pick your exact date

💡 My money-saving trick: summer Express Pass prices run 2-3 times the weekday rate. On a tight budget, go in midweek (Tuesday to Thursday), when skip-the-line costs the least and the crowds thin out too.

Survival notes for going with kids

• Head straight to Super Nintendo World after entry (mornings are the emptiest)
• Move to indoor attractions through the hottest part of midday (Harry Potter, Spider-Man)
• Bring a stroller. The park is enormous and your kid will be complaining by afternoon
• Pack sunscreen and a water bottle, because Osaka summer runs past 35°C

Tokyo Disneyland: the storybook option, and the family default

Who it is for

• Kids 3 to 12 years old, especially anyone raised on Disney animation
• Families who want wonder more than adrenaline
• Parents doing their first Japanese theme park with a child
• Also works for: babies and toddlers (free under 3, and the stroller rental setup is excellent)

Disneyland or DisneySea: how to choose

Comparison	Disneyland (Land)	DisneySea (Sea)
Mood	Storybook fantasy, the castle	Foreign adventure, the harbor
Ride intensity	Low (mostly gentle ride-throughs)	Medium to high (there are coasters)
Best age	2 and up can enjoy it	6 and up suits it better
Toddler friendliness	⭐⭐⭐⭐⭐	⭐⭐⭐
Parades	Day and night parades plus fireworks	Water show
What I would pick	The one for little kids	Adults or older kids

Where the savings are

• Free under 3 years old: the friendliest of the three parks toward toddlers, which makes it easy with a baby along.
• Child tickets (ages 4-11) run about ¥4,700-5,600, roughly 40% below the adult price.
• DPA (Disney Premier Access) costs ¥1,500-2,500 per attraction, quite a bit less than a Universal Express Pass, and you can buy it for just the 2 or 3 rides your kid actually cares about.
• Booking through the Klook Tokyo Disneyland and DisneySea 1-day passport with a 1stCoupon code saves a bit more again.

Survival notes for going with kids

• Disneyland suits kids under 10 years old better than DisneySea does.
• Rent a stroller (¥1,000 a day inside the park). Even if your kid has outgrown one, you will want it by mid-afternoon.
• Lockers are right at the entrance, so drop the spare bags before you go in.
• In summer, bring a cooling towel and a handheld fan, because you will use both while you wait.
• Lay a picnic mat 30-40 minutes before the parade to hold your spot. Consider that an unwritten Disney rule.

Nagoya Legoland: the park built for small kids

Who it is for

• Kids 2 to 10 years old, and any Lego obsessive.
• Families who hate lines and hate being packed in.
• Anyone who prefers building things to sitting in a ride vehicle.
• Not a great fit: kids over 10 years old, who will find the attractions babyish.

Why Legoland is the most underrated family park in Japan

Honestly, before I went I also assumed Legoland was just somewhere to park a toddler for a few hours. One trip with my younger one turned that around completely.

Real talk, three things caught me off guard:

1. Almost no waiting: even the busiest attraction in peak summer runs 15-30 minutes, which next to Universal's 180 minutes feels like a different planet.
2. The kid is playing, not being frightened. Building a Lego race car, steering a Lego boat, constructing a Lego house. Every attraction is hands-on and puts small hands and brains to work at once.
3. Tickets cost half what Universal does. For a family of 3 people, the difference pays for an extra hotel night.

Ticket savings

Ticket	Price	Notes
Adult 1-day	¥4,900-7,100	Floats with the season
Child 1-day	¥3,300-5,300	Ages 3-18
Park and aquarium combo	1-day ticket + ¥800	Worth adding. Kids love the SEA LIFE aquarium

Money-saving trick: buying at the gate costs ¥500-700 more than buying online. Book ahead, show the QR code, walk straight in. The best value is the ¥800 upgrade that adds the SEA LIFE aquarium, and grabbing a 1stCoupon code on the way through shaves off a bit more.

Survival notes for going with kids

• The park is compact, so half a day covers most of it. Put Legoland in the morning and something else in Nagoya in the afternoon
• The brick-building area is the main event: my younger one built things there for 2 hours and refused to head back to the hotel
• The SEA LIFE add-on costs ¥800 more and is clearly worth it
• Nagoya draws far fewer visitors than Tokyo or Osaka, so hotel rates run 30-50% cheaper

Pick a park by your kid's age

Kid's age	Best pick	Second choice	Skip
0-2	Tokyo Disney (free entry plus friendly facilities)	Legoland	Universal
3-5	Legoland (hands-on, no waiting)	Tokyo Disney	Universal
6-8	Tokyo Disney	Legoland	Universal (a few rides work)
9-12	Universal	Tokyo DisneySea	Legoland (too babyish)
13 and up	Universal	DisneySea	Legoland

What one summer day actually costs (2 adults + 1 seven-year-old)

Cost item	Universal	Tokyo Disney	Legoland
Tickets (2 adults + 1 child)	¥23,400	¥20,400	¥13,100
Skip-the-line	¥18,000 (3 people × Express 4)	¥9,000 (3 people × 2 DPA rides)	¥0 (not needed)
Food inside the park	¥6,000	¥6,000	¥4,000
Souvenirs	¥5,000	¥5,000	¥3,000
Day total	¥52,400 (about NT$11,843 / US$370)	¥40,400 (about NT$9,130 / US$285)	¥20,100 (about NT$4,543 / US$142)

The takeaway: a day at Legoland costs 38% of a day at Universal. The NT$7,300 (about US$228) you keep covers an extra night in a mid-range hotel.

Price update on 7/22: the ¥8,600-11,900 range above was the official pricing when I wrote this in January 2026. Across summer (7/1-8/31) both USJ and Disney run peak-day floating prices, and days where the top price jumps another ¥1,200-1,500 have already turned up. Legoland is still holding a ¥4,900 entry price on summer weekdays, the only one of the three that has not moved. USJ also rebuilds its whole ticket system from 9/1, which gets its own section below.

Klook Double Day park BOGO: how a family should play it

The mechanism first, then the tactics. Klook Taiwan has turned its monthly bonus event into a fixed rhythm this year: the sale opens on the double-digit date of each month, and the 7/7 round was a site-wide buy-one-get-one on theme parks worldwide, with both Universal and Disney tickets in the pool, which puts the next one on 8/8. Summer stacks a second layer on top, a Summer Festival running 7/6 to 8/2 with a limited-quantity drop every morning at 11:00 and extra high-value coupons on Mondays, Wednesdays and Sundays. From mid-May to mid-June the BOGO ran every Monday at 11:00, and a standalone worldwide Disney BOGO opened at 9:00 pm on 6/26, so Klook has spent the entire first half of the year using park tickets as bait.

I sat through the 7/7 drop myself, and three things are worth knowing before you try:

1. The free ticket is a second adult ticket of the same type: the best family play is two adults taking the BOGO, which halves the adult price outright, then buying the child ticket separately at full price. At the USJ peak-day price of ¥11,900, two adults and one kid effectively pick up a free adult ticket worth about NT$2,600 (US$81).
2. The drop is at 11:00, so be sitting on the page by 10:55: limited really does mean limited. I got in at 11:02 and the popular dates were already grayed out. Add the Klook Double Day park promo page to your favorites beforehand so you skip a search step at the moment it opens.
3. Tickets you win are usually tied to a fixed entry date or a redemption deadline. That is the price of the discount. If your dates are locked and the flights and hotel are booked, do not bet the whole budget on winning a coupon. Winning is a bonus, and if you miss it, Klook's regular prices already sit 3-5% under the official site, so just buy as planned.

There is a standing channel too. Klook's Monday 11 am markdown on Japan park tickets runs every week with no double-digit date to wait for, which suits families whose travel dates are still loose.

USJ moves to dynamic pricing on 9/1, and families come out ahead

USJ has announced that admission from 2026/9/1 onward moves to a new pricing system. A ticket for any given date climbs as demand builds after it goes on sale, so the earlier you buy the cheaper it is, and the entry price drops to ¥8,400, ¥500 below the current floor. The tickets covered by the change went on sale on 7/1. In plain terms, USJ pricing has gone from a calendar to an airfare curve: whoever settles their dates first wins, and if you hesitate a week and come back, that same date may have already stepped up a tier.

My older one watched me stare at the price table and asked whether tickets were stocks, and why they go up. That is a surprisingly accurate reading for a 7-year-old. The mechanism really does work like that, except it only climbs, so there is no dip to gamble on.

Families with young kids actually come out ahead under this system, for two reasons:

• The cheap days and the short lines are the same days: weekdays after school goes back on 9/1 are the cheapest dates on the calendar, and a family with a preschooler has no reason to be bound by school holidays in the first place. Avoiding peak days saves you more than the ¥1,500-3,500 price gap, it also saves you the 120-minute floor on the Mario line.
• Locking a price early fits family planning perfectly. Traveling with kids means booking flights and rooms well ahead anyway, so the dates are settled long before, and buying the tickets in the same sitting gets you the lowest price with no extra homework.

If you are going after September and want to work out whether an Express Pass pays for itself, I put the per-minute break-even math in a separate USJ ticket guide rather than repeating it here.

Planning this after 7/22? The catch-up timeline for an August trip

The May version of this section was a countdown table headed "six and a half weeks until opening." Summer has been running for three weeks now, so a countdown is useless and I have rewritten it for families leaving in August. Last year I started our hotel search 2 weeks late and every official Tokyo Bay property at NT$3,200 (~US$99) a night was full, which left us paying NT$5,500 (~US$170) a night for the fallback and NT$9,000 (about US$280) more on lodging alone. If you are leaving in August, right now is exactly that "two weeks late" moment, so work this table:

Your departure	What to do now	Why this is the moment
Early August (1-2 weeks out)	Buy tickets and the Express Pass or DPA immediately, no waiting	Express time slots around Obon (8/13-8/16) sell out first, and every day you wait removes another slot
Flexible around 8/8	Camp on the Klook Double Day BOGO at 11:00 on the morning of 8/8	The double-digit rhythm holds; the 7/7 round covered both Universal and Disney, and winning halves the adult ticket
Late August	Lock a free-cancellation room and watch the weather clauses	Peak typhoon season. Paying NT$200-400 (~US$6.2-12) extra for free cancellation up to 24-48 hours out is absolutely worth it
September onward	Wait for the 9/1 dynamic pricing, then buy early once your date is set	¥8,400 off-peak entry plus short weekday lines after school restarts is the most comfortable window of the year with kids

The part I want to underline: my older one is 7 years old this year and this was his second USJ trip, and I had the Klook USJ QR code e-ticket sorted by the end of April. The time that freed up went into working out the single-rider lane for Mario Kart (my 5-year-old cleared 122 cm by a whisker). What you regret missing is never the promo code, it is the time slot you wanted.

New for summer 2026 (I checked all of these in July)

• Super Nintendo World, USJ Osaka: the phase-two expansion Donkey Kong Country opened in December 2024 and is running through summer, headlined by a mine-cart coaster; Mario Kart moved to 100% reservation-only from late April
• The USJ One Piece triple bill: the Premier Show, Sanji's Pirates Restaurant and the Elbaf story ride all go live from 7/30 (details in the double-anniversary section above)
• Tokyo DisneySea: the new Fantasy Springs area, which opened on 6/6/2024, is still the single most popular part of DisneySea in summer, and its headline attractions need a separate DPA purchase or a timed-entry ticket to guarantee an entry window
• Nagoya Legoland: SEA LIFE added a limited-run Jurassic Deep Sea zone in July, included when you buy the aquarium combo

Refund traps in July and August typhoon season

West Pacific typhoons start tracking north from mid-July. On our 2024/8 trip a typhoon hit Japan hard, the park never declared a closure, the platform refunded nothing, and that is where the lesson came from. Three rules I hold to now:

1. Read the platform's weather clause before you buy any ticket: some Klook products are marked no refund once the park is open, while most KKday products carry 72-hour free cancellation
2. Always choose the free-cancellation room rate, valid up to 24-48 hours before departure. The NT$200-400 (~US$6.2-12) that flexibility costs is money well spent
3. Add trip interruption coverage to your travel insurance, because a standard policy does not necessarily cover rebooking flights when a typhoon pushes your dates

Tokyo Disney vs USJ Osaka vs Nagoya Legoland: family fit, measured

The sections above take the three parks apart one at a time, but the question I keep getting is this: I only have one weekend, so which one do I go to? Honestly there is no standard answer, and the choice runs on three axes: your kid's age, your family's pace, and how much transit they can absorb. The table below is what I put together after three trips with my own kids, turning family fit into 6 measurable dimensions. No talk of magic, just hard conditions.

Dimension	Tokyo Disney (Land + Sea)	Universal Studios Japan (Osaka)	Nagoya Legoland
Age range	3-12 (mostly Land) / 6 and up (Sea)	8 and up, 122 cm or taller	2-10 golden window
Crowd density, weekday vs weekend	About 60,000-70,000 on weekdays / 80,000-90,000 on weekends (close to the 90,000 cap)	40,000-50,000 on weekdays / 70,000-80,000 on peak summer weekends	8,000-12,000 on weekdays / 15,000-20,000 on weekends (easily the loosest)
Adult ticket in peak season	¥7,900-10,900 floating	¥8,600-11,900, at the top of the range almost every summer day	¥4,900-7,100, with ¥4,900 common off-peak
Child pricing structure	Child ticket for ages 4-11, free under 3	Child ticket for ages 4-11, free under 3	One child ticket covering ages 3-18, free under 3 (counting everyone under 18 as a child is the most generous rule of the three)
Family facilities (nursing rooms / stroller rental)	4 nursing rooms plus changing tables everywhere, strollers ¥1,000 a day, wheelchairs bookable	2 nursing rooms, strollers ¥1,100 a day, 1 baby care center	2 nursing rooms plus plenty of family restrooms, strollers ¥500 a day (the cheapest)
Transit time from the city	Tokyo Station to Maihama, about 15 minutes on JR	Shin-Osaka to USJ, about 25 minutes with a change to the Sakurajima Line	Nagoya Station to Kinjofuto, about 24 minutes on the Aonami Line

Straight talk, sorted by age:

• Ages 2-4 (still in the stroller): Legoland first, Disneyland second. Do not take them to USJ. The height limits mean you pay full price and your kid gets on 3 attractions.
• Ages 5-7 (100-115 cm): Disneyland wins. This is the age that screams at the parade, and Pooh's Hunny Hunt and Buzz Lightyear land exactly right. Legoland still works, but the kid starts finding parts of it babyish.
• Ages 8-10 (120 cm and up): Mario Kart is finally rideable, and this is the age where a USJ ticket pays for itself. DisneySea opens up around here too, with the Tower of Terror and Toy Story Mania.
• 11 years old and up: USJ, no argument. Legoland gets called babyish, and Disneyland does not carry enough intensity for this age unless you have a hardcore Disney kid.

The two mistakes families make most often:

1. Choosing a park on the child-ticket age ceiling: Legoland counting 18-year-olds as children is generous, but a kid over 12 years old usually does one loop and wants to leave. Saving on the ticket is not the same as having a good day.
2. Underestimating how transit fatigue stacks up. Fifteen minutes from Tokyo Station to Disney sounds like nothing, but staying in Shinjuku or Shibuya adds another 15-20 minutes of connections, and 2 hours of travel in a day with a kid burns roughly a third of their energy before you even walk through the gate.

Real talk, one line: budget is the second consideration. Your kid's height and their patience for lines are the first. Taking a 5-year-old to USJ in summer, standing 120 minutes in the Mario line and finding out at the front that they cannot ride, is a meltdown I lived through once and never need again.

⚠️ Things to watch out for at Japanese parks with kids

I walked into every one of these myself, so here they are in writing to save you a few meltdowns:

1. ⚠️ Height limits are stricter than you expect: Mario Kart at USJ needs 122 cm and the Flying Dinosaur needs 132 cm, and the staff measure against a physical height stick at the entrance. Do not force a USJ trip with a child under 4 years old, and remind yourself that buying a ticket does not mean they get to ride. My younger one was 105 cm on that trip and 60% of the attractions were closed to her, which is what all the crying was about.
2. Watch the timed trap in skip-the-line passes: both Express Pass and DPA are split into time windows rather than valid all day. The first time I bought an Express 4 I never checked the windows, walked in at 3 pm, and most of my slots had already expired. ¥10,000 bought me exactly 1 attraction, so treat that as a genuine risk.
3. ⚠️ Refund terms for typhoons and heavy rain: Japanese parks generally refund only when the park itself declares a closure. Deciding on your own that a typhoon is coming and staying home gets you nothing back. Read the weather refund policy before you buy on Klook or KKday, because some platforms say no refund once the park is open while others give you 72-hour free cancellation. Check before you carry the risk.
4. Overnight bags and the locker warning. Park lockers are nearly all gone before noon in summer, and a full-size suitcase does not fit a standard locker (400×350×570mm) at all. Leave the bags at the hotel or in a JR station coin locker before you go in, unless you enjoy dragging a suitcase around a theme park and questioning your life choices.
5. ⚠️ Bringing medication legally: every year there are cases of children's fever reducers and cough syrups (the ones containing codeine or pseudoephedrine) being stopped at Japanese customs. Keep it to a one-month supply per person, leave everything in the original packaging, carry a doctor's prescription or an English-language information sheet, and declaring it at customs is the safest route.
6. Heatstroke beats the lines as the real summer danger. Ground temperature in Osaka in July and August regularly reaches 42°C, and my older one went red-faced and nauseous at midday in USJ last year. The risk is real, so cooling towels, electrolyte drinks and a midday nap back at the hotel all belong in the plan.

Where to buy and how to save

Whichever park you pick, never buy at the gate. Booking on a platform ahead of time is both cheaper and one less line to stand in.

Platform	Good for	1stCoupon code
Klook Tokyo Joypolis indoor park 1-day pass	All three park tickets plus skip-the-line	Site-wide code
KKday Japan Rail Pass pre-order page	Ticket and transport bundles	Limited-time discount code

The savings formula:

Klook ticket (3-5% below the official site)
+ 1stCoupon code (another 5%)
+ credit card foreign spend rebate (3-8%)
= 10-15% saved in total

FAQ

Q: Is it unbearably hot at a Japanese theme park in summer? A: Yes. Japan averages 32-36°C in July and August. Bring sunscreen, a hat, a cooling towel, a handheld fan and plenty of water, and lean on the indoor attractions and air-conditioned rest areas.

Q: Can I fit two parks into one trip? A: You can. The pairing I would recommend is Tokyo Disney (2 days) plus Nagoya Legoland (1 day), 1.5 hours apart on the shinkansen. Or Osaka Universal (1 day) plus Nagoya Legoland (1 day), 50 minutes apart.

Q: What if my kid is not tall enough? A: Universal has the most height-gated attractions (thresholds at 102 cm, 107 cm and 122 cm), so measure your kid before you leave home. Most Disney attractions carry no height limit. At Legoland almost everything is open.

Q: Is skip-the-line worth buying? A: At Universal in summer, buy it (otherwise a whole day gets you 3 or 4 attractions). At Disney it depends (you can skip it on a weekday). At Legoland you do not need it, because the lines are short to begin with.

Q: Where should I stay? A: For Universal, a hotel near JR Universal City Station. For Disney, inside the resort or around Shin-Urayasu. For Legoland, around Nagoya Station or at the Legoland hotel, which kids adore. Book through the Agoda 15% off popular Japan hotels page with a 1stCoupon code for the best price.

My final call

Your situation	Pick this	Why
Kid aged 2-5	Legoland	No waiting, hands-on, cheap
Kid aged 3-8 and a Disney fan	Tokyo Disneyland	Storybook experience, gentle attractions
Kid 9 or older	Universal Studios Japan	Big rides plus a deep franchise lineup
Tight budget	Legoland	A day costs 38% of a USJ day
First overseas trip with a child	Tokyo Disney	Friendliest, safest, hardest to get wrong

Get the park right and a Japanese theme park day turns into the thing your family talks about for years. Get it wrong and it is a very expensive disaster. I hope this makes your pick an easier one.
