Indoor Playgrounds in Tokyo: Where Kids Can Burn Energy on a Rainy Day

Dollar amounts are approximate at $1 ≈ ¥158 (October 2026). You pay in yen.

The catch is that most of the useful details live only on Japanese websites: price calendars, sock rules, which ages get in free, and whether you need a ticket in advance. I’m a dad raising a daughter in Tokyo, and this guide pulls those rules from each facility’s official pages so you can pick one before you leave the hotel.

Ramen Dad’s note: We have our usual indoor play spots for rainy days in Tokyo. Check each place’s rules before you go; many details live only on Japanese websites.

Quick answer: which Tokyo indoor playground fits your kids

Short version: ASOBono! for energy, Tokyo Toy Museum for babies, KidZania for school-age kids.

How Tokyo indoor playgrounds work (the rules that surprise visitors)

Before the individual places, a few patterns repeat across Japanese indoor play spaces:

• Adults pay too. At ASOBono!, Kid-O-Kid and the Tokyo Toy Museum, each adult has an entry fee. It’s usually a flat fee, not timed like the kids’.
• Kids are timed, adults aren’t. ASOBono! charges children per 60 minutes plus 30-minute extensions; Kid-O-Kid charges per 30 minutes plus 10-minute extensions. You pay the extra when you leave.
• No adults-only entry and no drop-off. ASOBono! won’t let a child in without a guardian (a parent, or someone 20 or older in their place), and one adult can bring up to five children. Adults can’t enter on their own either.
• Socks and food rules are strict. ASOBono! asks children to take their socks off to play. Snacks are not allowed inside, only drinks in bottles with a sealable lid.
• Re-entry is often not allowed. Plan your lunch before you go in, or buy a ticket that allows re-entry.
• Price calendars. Several places charge more on weekends, holidays and school breaks. Japanese pages often show this as a color-coded calendar rather than a list.

Ramen Dad’s note: As a local, I’d say the sock and food rules are what surprise visitors. Pack spare socks and eat before you go in.

ASOBono!: the biggest indoor playground in Tokyo

ASOBono! is in Tokyo Dome City and calls itself the largest indoor kids’ playground in Tokyo. It’s aimed mainly at children aged 0 to 6, and it’s the place I’d send a family whose kids need to run.

What’s inside

• Adventure Ocean: a ball pool with about 40,000 balls, climbing walls, trampolines and slides.
• Toy Forest: board games, building blocks and character play sets.
• Colorful Town: pretend play, with a doll-care room and toy shops, a restaurant and a sushi counter.
• Pleasure Station: about 100 m² of Tomica cars and Plarail train sets. Train-mad toddlers can stay here a long time.
• Hi-Hi Garden: a baby-only area for 0–24 months, with soft blocks and a small ball pool.

There are diaper-changing rooms, nursing rooms and a vending machine that sells baby food.

Hours and prices

Hours: weekdays 10 a.m.–6 p.m.; Saturdays, Sundays and holidays 9:30 a.m.–7 p.m. Last entry is 70 minutes before closing, and hours vary, so check the calendar on the official site.

ASOBono! has four price levels (A to D), shown on its calendar by date:

“Child” means 6 months through elementary school; “adult” means junior-high age and up. Babies 5 months and under are free. The online 120-minute tickets are sold through Asoview until noon on the day. There are also evening tickets (about 20% off the child 120-minute price, entry from 3 p.m. on weekdays and 4 p.m. on weekends) and a morning pass with 10 minutes’ early entry on B–D days. Full details are on the prices page.

Re-entry: only with the child all-day pass (and the adults with that child). Every other ticket is one entry, and all-day pass sales can stop when it’s busy.

Family of four: 2 hours on a “C” day

With the online 120-minute ticket on the same day it’s ¥7,100 (≈$45), compared with ¥7,200 at the counter. That’s a small saving, and the 120-minute limit still applies. It isn’t a priority-entry ticket either: ASOBono! says you may have to wait to get in when it’s crowded, and entry can be refused on very busy days.

Getting there

ASOBono! is along Hakusan-dori inside Tokyo Dome City (1-3-61 Koraku, Bunkyo-ku). Nearest stations: Korakuen (Marunouchi and Namboku lines, Exit 2), JR Suidobashi (East Exit), Suidobashi on the Toei Mita Line (Exit A4) and Kasuga on the Oedo Line (Exit A1). With a stroller, the official step-free route starts at Korakuen: go through LaQua, take the elevator to the 2nd floor, cross the overpass, and take the South Elevator down to ASOBono! on the 1st floor. Access page

Ramen Dad’s note: We’ve been to ASOBono! with my daughter. Plan lunch before you enter, since you may have to wait to get in.

Tokyo Toy Museum: best for babies and toddlers

The Tokyo Toy Museum is in Yotsuya, run by a certified nonprofit (Art and Play Creation Association). It’s a hands-on museum: almost everything is a wooden or traditional toy children are encouraged to touch, explore and play with. It’s calmer than ASOBono!, and it has a room just for babies and toddlers under 3.

The baby room needs a timed slot

The Akachan Mokuiku Hiroba (baby wooden-toy room) is for children 2 and under only. Children 3 and up, including older siblings, can’t go in. You choose a time when you book, and each slot is one hour. The diaper-changing and nursing spaces can be used outside your slot. Same-day time changes aren’t accepted.

Hours, closures and new prices

• Open: 10 a.m.–4 p.m., last entry 3:30 p.m. On weekdays you can leave and come back; on weekends and holidays you can’t.
• Closed: Thursdays, plus maintenance days in February and September and the New Year holiday.
• Prices change on November 1, 2026, when advance tickets are introduced:

Advance tickets can be bought until 11:59 p.m. the day before. When the day’s tickets sell out, the door stops selling too, so book online before you go. Tickets can’t be cancelled or refunded after 10 a.m. on the day. Children of elementary-school age and under must come with a guardian. Official visitor info (Japanese)

Family of four (from Nov 1): ¥4,200 (≈$27) with advance tickets, ¥5,200 (≈$33) same day.

Getting there: 4-20 Yotsuya, Shinjuku-ku, a 5-minute walk from Exit 2 of Yotsuya-sanchome Station (Marunouchi Line).

Ramen Dad’s note: We used the baby area at the Tokyo Toy Museum when my daughter was little. Book online before you go; same-day tickets can sell out.

Kid-O-Kid at Ariake Garden: a shorter session near Odaiba

Kid-O-Kid (“KIDOKID”) is a chain of indoor playgrounds run by Bornelund, a Japanese toy company. In Tokyo there are three: Ariake Garden, Yomiuriland and AEON Mall Musashimurayama. Ariake is the one visitors are most likely to pass, since it’s in the Odaiba bay area.

Hours (Ariake): 10 a.m.–7 p.m., last entry 6:30 p.m. It closes on days when the whole Ariake Garden mall is closed.

Adults can swap in and out, so one parent can shop while the other plays. There’s a zone just for babies aged 6 to 18 months, plus a nursing room, a diaper-changing room, drink vending machines and stroller parking inside. Toilets outside the play area mean the parent and child both step out for a while. Kid-O-Kid Ariake (Japanese)

Family of four, 60 minutes on a weekday: ¥4,200 (≈$27). On a weekend: ¥4,600 (≈$29).

Getting there: Ariake Garden, 4th floor (2-1-8 Ariake, Koto-ku). Nearest stations are Ariake and Ariake-tennis-no-mori on the Yurikamome, and Kokusai-Tenjijo on the Rinkai Line. If you’re also doing teamLab Planets in Toyosu, it’s the same side of the bay; see my teamLab Planets vs Borderless guide.

KidZania Tokyo: role-play jobs for ages 3–15

KidZania is a kid-sized city where children do short “jobs” (firefighter, pilot, pizza chef, dentist) and get paid in the park’s own currency. It’s a different idea from a playground: kids queue for activities, and it works best from about age 3 to 15.

The rules families need:

• Ages 3–15 take part. Children 2 and under get in free without a reservation, but they can’t do the activities.
• Two shifts a day, with everyone leaving between them. Children can’t step out and come back during a shift, and once your group leaves, you can’t re-enter. Parents can step out temporarily under KidZania’s rules: if every child is 6 or older, all guardians may leave for a while; with a child aged 5 or under, one guardian has to stay inside. Details are on the guardians page (Japanese).
• Booking: online, right up to the day: until noon for the first shift and 6 p.m. for the second. Same-day tickets are also sold at the venue, in limited numbers.
• No adults-only or kids-only bookings for children 3–12.
• Food: you can’t bring food in (allergy-safe meals and baby food are allowed), but water bottles and one plastic bottle per person are fine.
• English: see the next section.

Prices change by date, shift and age, and the official fee table is behind the booking system, so check the official admission page with your dates. KidZania Tokyo is on the 3rd floor of LaLaport Toyosu 1, an 8-minute walk from Toyosu Station (Yurakucho Line Exit 2, or the Yurikamome).

Can kids who don’t speak Japanese enjoy KidZania?

Yes, but not every activity is in English. Every activity includes simple English greetings, selected “E@K” activities run in English, and on “English Wednesday” staff use more English. English program page

For a more structured option, the English Activities Program is a guided run of five activities in a row, in English, with Global Staff leading small groups of up to 6 kids. KidZania says Japanese ability isn’t required. From November 1, 2026, the five activities are Pizza Shop, Subway (train driver), Dental Clinic, Ponzu Factory and Fire Department.

It’s booked separately from regular admission. Parents must be there at the start and end, reservations can’t be changed or cancelled from 3 days before the visit, and if you’re bringing kids who won’t join the program, KidZania asks you to book by phone. Program details and November 1 course change

Ramen Dad’s note: We’ve been to KidZania with my daughter. For kids who don’t speak Japanese, look at the English activities and English Wednesday.

Just outside Tokyo: Yokohama Anpanman Children’s Museum

If your toddler knows Anpanman, one of Japan’s most beloved characters for young children, the Yokohama museum is worth the trip. It’s about 30 minutes from Tokyo Station to Yokohama on the JR Tokaido Line, then a 10-minute walk from Yokohama Station’s East Exit, or 3 minutes from Exit 3 of Shin-Takashima Station.

• Tickets: ¥2,200–¥2,800 (≈$14–$18) per person, depending on the date. Everyone aged 1 and up pays, adults included.
• Book ahead: the 2nd and 3rd floor museum requires a date-and-time web ticket bought in advance.
• Free part: the 1st floor shops and restaurants are free to enter.
• Last museum entry: 4 p.m.

Family of four: ¥8,800–¥11,200 (≈$56–$71). Official ticket page (Japanese)

What should you book in advance?

• Tokyo Toy Museum: buy ahead when you can. From November 1 advance tickets are cheaper, the baby room needs a one-hour time slot, and same-day sales stop when the day’s tickets run out.
• Yokohama Anpanman Children’s Museum: the museum floors need a date-and-time web ticket bought in advance.
• KidZania Tokyo: book online for your shift, and earlier if you want the English Activities Program.
• ASOBono! and Kid-O-Kid: no entry reservations needed. At ASOBono! that doesn’t guarantee you walk straight in on a busy day.

Which one on which kind of day?

• Rainy weekend, toddler and a 5-year-old: ASOBono!, with long weekend hours and plenty for active under-6s. Rainy weekends can be busy, though, and you may have to wait to get in, so check the official site before heading over.
• Baby under 2: the Tokyo Toy Museum’s baby room (book the time slot), or ASOBono!‘s Hi-Hi Garden.
• Jet-lagged early riser: ASOBono! opens at 9:30 a.m. on weekends. My guide to eating out in Japan with a picky eater covers where to get breakfast first.
• School-age kids who’d be bored in a ball pit: KidZania, or teamLab.
• Need to fill an hour near Odaiba? Kid-O-Kid at Ariake Garden.
• Tokyo Disney is the main event: use a playground on the day before as a rest day. My Tokyo Disney with a toddler guide explains why a rest day between park days helps.

With a stroller, all five are reachable by train; my stroller or carrier guide covers Tokyo stations and elevators.

FAQ from parents

“Do I need to bring socks?” It depends on the place. ASOBono! asks children to take their socks off. Many Japanese play spaces have their own rule, so pack a spare pair for each child and check the rules on arrival.

“Can I drop my kids off and go shopping?” No. ASOBono! requires a guardian with every child and won’t admit adults alone, and KidZania doesn’t take bookings for kids 3–12 without an adult. At Kid-O-Kid, the adults with your kids can swap, which is the closest you’ll get.

“Can we bring lunch?” Not inside ASOBono! (no meals or snacks; baby food is fine) or KidZania (allergy meals and baby food only). Eat before you go in, especially where re-entry isn’t allowed.

“What if we arrive and it’s sold out?” That’s the real risk at the Tokyo Toy Museum, where the door stops selling once the day’s tickets are gone, and at the Anpanman museum, which needs a date-and-time web ticket. ASOBono! doesn’t take entry reservations, but on crowded days you may have to wait, or may not get in at all.

“Can my 2-year-old and 6-year-old play together?” Mostly, but check the baby areas. At the Tokyo Toy Museum, the baby room is for children 2 and under, and kids 3 and up (siblings included) can’t go in, so the family may split up for that hour. At ASOBono!, Hi-Hi Garden is for babies 0–24 months. The rest of each place is open to both ages.

“Is my 9-year-old too old?” For ASOBono! and the Tokyo Toy Museum, probably, though both technically allow elementary-school kids. KidZania (3–15) is the better fit.

Before you go: indoor playground checklist

1. Match the place to your youngest child’s age, then check the older one won’t be bored.
2. Buy tickets ahead for the Tokyo Toy Museum (from Nov 1, advance prices are cheaper; the baby room needs a time slot) and the Anpanman museum (date-and-time ticket).
3. Check the price calendar for your date; weekends and holidays cost more.
4. Pack a spare pair of socks per child and a lidded water bottle.
5. Eat first. Most places don’t allow food, and many don’t allow re-entry.
6. Note the last entry time: 70 minutes before closing at ASOBono!, 3:30 p.m. at the Tokyo Toy Museum.
7. Have cash or a card ready for extensions, which you pay on the way out.

Ramen Dad’s note: We do have a favorite for wet afternoons. Whichever you choose, book ahead, eat first and check the last entry time.

Prices, hours and rules were checked against each facility’s official website on October 9, 2026. Price calendars change by date, so confirm on the official page for your day.
