Rainy-day indoor playgrounds in Tokyo for babies and toddlers (2026)

For babies and toddlers on a rainy day in Tokyo, ASOBono! at Tokyo Dome City is the biggest walk-in indoor playground, and it is cheapest on a weekday: 2 hours for two adults and two children costs ¥5,600 on a weekday against ¥7,200 at the weekend. The Tokyo Toy Museum is the quieter, cheaper choice if you book ahead, and the free kosodate hiroba play rooms run by Tokyo’s wards cost nothing.

Every price, age rule and opening time below comes from the venue’s official site, checked on 27 Oct 2026. Prices here change more often than most attractions, and ASOBono! has announced new weekend prices from 1 December 2026, so check the official page on the day you go. This guide has no affiliate links.

Which one to pick

All costs are for two adults and two paying children (aged 6 months to primary school at ASOBono! and the Toy Museum, 1 to 12 at Kid-O-Kid, 1 and over at the Anpanman museum). A baby under the paying age lowers the total.

ASOBono! and Toy Museum figures are on-the-day counter or advance prices checked on 27 Oct 2026; the Toy Museum figure uses prices that start on 1 November 2026. Kid-O-Kid figures are the chain’s standard prices; a few stores charge differently.

ASOBono! at Tokyo Dome City

ASOBono! (アソボ～ノ！) is Tokyo Dome City’s indoor kids’ playground at 1-3-61 Koraku, Bunkyo-ku, aimed mainly at children up to about 6. There is a ball pool around a large ship, climbing, slides, a train area and pretend-play “town”, plus a separate baby-only area, the Hai-Hai Garden, for babies from 0 to 24 months. Children play barefoot. The main active areas are for children who can walk on their own.

Who pays and how pricing works

• Children (6 months to primary school) pay for the first 60 minutes, then for every extra 30 minutes.
• Adults (junior high school age and up) pay one admission fee with no time limit.
• Babies aged 5 months and under are free. Children cannot go in without an adult, and adults cannot go in without a child.
• Days are priced A to D. On the October 2026 calendar, normal Tuesdays to Fridays were A, Mondays B, normal weekends C, and the 10–12 October holiday weekend D. Check the official calendar for your date.

A and B prices stay the same after 1 December 2026. A child 1-day pass with re-entry costs ¥2,100, but it is sold only on A days and can sell out on busy days. Showing the Tokyo Dome City app or a Mitsui Shopping Park points card takes ¥100 off each child’s first 60 minutes and each adult admission (¥200 off the 1-day pass), for up to five people per card.

What a family of four pays

These are admission prices only, worked out from the official price tables. So a normal weekday saves ¥1,600 on a 2-hour visit now, and ¥2,200 from December.

Ways to cut the wait or the cost

• Morning Skip Pass (B, C and D days, ¥1,350–¥1,550 per person, same price for adults and children): a date-specific online ticket that lets you in from 10 minutes before opening until 30 minutes after. Sales for the next month open at 10:00 on the 1st, and you can buy until 23:59 the day before.
• Evening ticket (B, C and D days): about 20% off 2 hours of child play if you go in after 15:00 on weekdays or 16:00 at weekends and holidays. Buy it online by 12:00 on the day.
• Asoview 120-minute ticket: a child ticket for 2 hours at ¥1,800–¥2,450 depending on the tier.
• Morning and Evening tickets are sold only on the TOKYO DOME CITY e-Ticket Store, and none of these online tickets allow re-entry.

Hours, booking and facilities

• Hours: weekdays 10:00–18:00; weekends and holidays 9:30–19:00 (October 2026 calendar). Last entry is 70 minutes before closing, and hours can change for events.
• No reservations: you may be asked to wait when it is busy, or not be let in at all, and your whole group needs to arrive together. ASOBono! asks you to pre-register online, agreeing to its notes and disclaimer, before you visit, which makes entry quicker.
• Baby room: there is a baby room with nappy changing, a nursing room and hot water, plus stroller parking.
• Strollers: Tokyo Dome City lends strollers for free against a returnable ¥100 coin at LaQua 1F and 2F (4 months to under 4 years, up to 100 cm) and the Korakuen Hall building 1F (1 month to 4 years, up to 18 kg). They can’t be booked and must stay inside Tokyo Dome City.
• Getting there: Toei Mita Line Suidobashi Station exit A2 has a lift (A4 is stairs only); JR Suidobashi East exit and Tokyo Metro Korakuen Station are also close.
• Payment: credit cards, e-money and code payments are accepted.

Klook and other passes: we found no Klook ticket for ASOBono! on its own. We have not linked the Tokyo Dome City all-in-one pass that includes ASOBono!, because its stated age rules for babies did not match ASOBono!’s own. Buy entry at the counter or through the official online tickets above.

Tokyo Toy Museum, Yotsuya

The Tokyo Toy Museum (東京おもちゃ美術館) is at Yotsuya 4-20, Shinjuku, five minutes from exit 2 of Yotsuya-sanchome Station on the Marunouchi Line. It is a hands-on toy museum with several play rooms. Prices go up on 1 November 2026.

• Hours: 10:00–16:00, last entry 15:30. Closed on Thursdays, plus maintenance days in February and September and over New Year.
• Advance tickets can be bought until 23:59 the day before. If the day’s tickets sell out, the counter stops selling too.
• Baby room: the wooden baby room is only for children aged 2 and under; older siblings cannot go in. Use is in 1-hour slots chosen when you book. Nappy-changing and nursing space can be used outside your slot.
• Re-entry is allowed on weekdays but not at weekends or on holidays.
• For regular visitors: a 6-month weekday passport costs ¥4,300 per adult and ¥3,300 per child from 1 November, with ¥200 off for Shinjuku residents.

Kid-O-Kid at Ariake Garden

Kid-O-Kid (キドキド) is a chain of indoor playgrounds run by the toy company Bornelund. Its Ariake Garden store is on the 4th floor of the Ariake Garden mall in Koto-ku, open 10:00–19:00 (last entry 18:30), about 12 minutes on foot from Ariake Station on the Yurikamome or 15 minutes from Kokusai-Tenjijo Station on the Rinkai Line. Inside there is a nursing room, a nappy-changing room and stroller parking.

Time-based play adds up fast, so the 1-day pass is better value from about 2 hours on a weekday or 2.5 hours at the weekend. Passes are sold until they run out on the day. Babies aged 5 months and under go in free. One adult can bring up to three children. Every visitor has to create an account and complete the entry form on Bornelund’s online reception site before going in, and the site is in Japanese.

Free option in the same building: the mall has a free play area, Kids Ariake Garden, for children aged 0 to 6 on the 4th floor, and baby lounges on the 4th and 5th floors with nappy tables, a microwave and hot water for formula.

Yokohama Anpanman Children’s Museum

The Yokohama museum is an option for Anpanman fans, but it is the most expensive one here. Tickets for the 2nd- and 3rd-floor museum cost ¥2,200–¥2,800 per person aged 1 and over depending on the date, and you must buy a date-and-time web ticket in advance. Last entry to the museum is 16:00. The 1st-floor shops and restaurants are free to enter. A family of four with two children aged 1 or over pays ¥8,800–¥11,200.

Free indoor play: kosodate hiroba and jidōkan

If you live in Tokyo, the cheapest rainy-day option is a kosodate hiroba (子育てひろば), a free play room for babies and young children, mainly 0 to 3, and their parents. They have toys, picture books and staff you can ask about childcare, and many run short events. Jidōkan (children’s halls) cover a wider age range. The Tokyo Metropolitan Government publishes a list of every hiroba in Tokyo, and each ward and city has its own page.

Shinjuku Kodomo Sōgō Center “Oya to Ko no Hiroba”

• Who: babies and children from 0 to preschool age, with a parent or carer. Primary school children cannot use it.
• Open to everyone: no booking needed, and families from outside Shinjuku can use it. Shinjuku residents get a registration card on their first visit; everyone else fills in a temporary pass form each time.
• Hours: every day except 29 December to 3 January, holidays included. Weekdays 9:30–18:00; weekends, holidays and school holidays 9:00–18:00.
• Facilities: nursing space, nappy-changing tables and baby beds, and a kitchen with a microwave, kettle and fridge. You can eat in the flooring area at lunchtime (12:00–13:00) and snack time (14:45–15:15).
• Where: 1st floor of the Kodomo Sōgō Center, Shinjuku 7-3-29, 7 minutes from Higashi-Shinjuku Station (Oedo and Fukutoshin lines).
• Some events are for Shinjuku residents only and need booking.

Your own ward’s hiroba

Each ward sets its own rules. Some hiroba are open to anyone, like Shinjuku’s, and some are only for registered residents of that ward. Some limit how many families can be inside at once, ask adults to wear socks, or close on Sundays. Check your ward’s page before you go.

For families living in Japan

Most of these places work fine for foreign residents, but booking is mostly in Japanese.

• Easiest without Japanese: ASOBono! has an English price and hours page and lets you walk in. Shinjuku’s hiroba is also walk-in, with a short Japanese form.
• Japanese-only steps: the Tokyo Toy Museum’s online tickets, Kid-O-Kid’s online account and entry form, and the Anpanman museum’s web tickets.
• Local discounts: the Tokyo Dome City app and Mitsui Shopping Park points cards take ¥100 off per person at ASOBono!, and the Toy Museum’s weekday passport is ¥200 cheaper for Shinjuku residents.
• Regular visits: Kid-O-Kid sells a weekday monthly pass (¥6,600 for one child and one adult, ¥3,300 for each extra child bought at the same time), and the Toy Museum sells a 6-month weekday passport.

Common mistakes

• Turning up at the Toy Museum on a Thursday. It is closed every Thursday.
• Expecting to book ASOBono!. There are no reservations; only the Morning Skip Pass gets you in ahead of the queue.
• Planning to pop out for lunch. At ASOBono! only the child 1-day pass allows re-entry, and the Toy Museum has no re-entry at weekends.
• Forgetting the online forms. ASOBono! asks you to pre-register online and Kid-O-Kid requires its online entry form. Do them at home before you go.
• Using old prices. The Toy Museum’s prices go up on 1 November 2026 and ASOBono!’s weekend and holiday prices on 1 December 2026.
