Odaiba with kids: ages, rules and a plan for rain

Odaiba works for families for a plain reason: almost everything a child wants is inside three malls a short walk apart, on a train line with no traffic to deal with. The bad day is the one where you queue for LEGOLAND and find the entry slot is gone, or buy a Joypolis Passport for a child who is too short for the rides.

This guide goes attraction by attraction: the age that gets the most out of it, the rules, and what we would skip.

Quick guide by age

LEGOLAND Discovery Center (DECKS)

Sweet spot: ages 3 to 10. It is an indoor LEGO play centre with a DUPLO area for the youngest, a pedal ride, a laser ride, a 4D cinema and building zones. Under 3 goes free.

Two rules to know before you book:

• Adults must bring at least one child aged 15 or under. A group of adults or older teens (16+) without a younger child cannot get in. The only exception is the occasional Adult Night for guests 16 and over.
• Third-party tickets are “unreserved”, per the centre’s own FAQ: you are let in when a slot is free. On weekends and holidays, book the official timed ticket at least 24 hours ahead. Klook is fine on ordinary weekdays.

On Merlin’s Apprentice, children 90–120 cm ride with an adult. On weekends and holidays, visits may be limited to 3 hours. Full details on our LEGOLAND page.

Tokyo Joypolis (DECKS)

Sweet spot: 130 cm and up. Joypolis is an indoor ride park, and the rules are by height, per ride:

• 90 cm+: Spicy Taxi, House of the Dead Scarlet Dawn
• 110 cm+: Wild River, Wild Wing, Wild Jungle Brothers
• 130 cm+: Gekion Live Coaster, Half Pipe Tokyo, Transformers Human Alliance Special
• 140 cm+: Storm G (140–200 cm), the Sadako curse house (140–185 cm)
• Age 7+: Murder Lodge

Preschool children get in free. The child price covers elementary to high school: ¥1,400 entry or ¥5,000 for the Passport with unlimited rides. For a child under 110 cm, pay entry only for the adult who watches, or skip Joypolis and spend the time at LEGOLAND. See the Joypolis page for the Evening Passport and where to buy.

Unko Museum (DiverCity 2F)

Sweet spot: ages 4 to 10, and any adult who finds the idea funny. It is a colourful photo-and-play museum built around cartoon poop: My Poop Maker, the Poop Volcano, a dancing room and a neon gate.

• Children 3 and over pay (¥1,100–¥1,200 by date); under 2 free, up to two per adult.
• Under-7s must be accompanied by a guardian of junior-high age or older.
• No food or drink, no re-entry, and no luggage storage. Leave big bags somewhere else before you come.

Klook is one of the museum’s listed official sellers. More on the Unko Museum page.

Tokyo Trick Art Museum (DECKS Seaside Mall 4F)

Sweet spot: ages 5 and up. Children pose inside Edo-themed optical illusions while you take the photo. The child price is ¥800 for ages 4 to 14; 3 and under free. No food or drink inside. It is short and cheap, which makes it a good filler between bigger things. See the Trick Art page.

Daiba Haunted School (DECKS Seaside Mall 4F)

Sweet spot: confident older children and teens. It is a flashlight walk through a “cursed” abandoned school, inside the retro Daiba 1-chome shopping street. The price is ¥900 at any age, cash only at the door.

Rules: everyone signs a consent form. Preschool children are admitted only with an adult of high-school age or older. Visitors who can’t walk unaided, pregnant visitors and people prone to panic attacks are not admitted. Guests need Japanese, English or Mandarin, or a companion who does. We would not take a nervous six-year-old, even though the rules allow it. Details on the Haunted School page.

AniTouch Aqua City Odaiba (Aqua City 3F)

Sweet spot: toddlers to about 10. An indoor animal-contact zoo with more than 30 species, including capybaras and ring-tailed lemurs. There is no time limit once you are in, and animal feed is sold separately.

It opens 11:00–19:00 on weekdays and 11:00–21:00 on weekends and holidays, so it also works as an evening stop after dinner in Aqua City.

Little Planet (DiverCity)

Klook sells tickets for Little Planet at DiverCity Tokyo Plaza. We have not been able to confirm its age rules or prices from an official source, so read the listing’s conditions before you book.

teamLab Planets (Toyosu, one area over)

Sweet spot: ages 4 and up, and it is the one on this list teenagers remember. It is in Toyosu, not Odaiba: Shin-Toyosu Station on the Yurikamome, about a quarter of an hour from the Odaiba stations.

Family rules from the official page:

• Visitors walk the water artworks barefoot, and the water can reach knee height, even on adults. Free rental shorts come in sizes XS to 6L.
• Children with an inseam under 40 cm cannot walk the koi water work unless carried. With a toddler, plan on carrying them there.
• Some floors are mirrors. Skirts are awkward there, so wear shorts or use the free wraps.
• Free lockers after the gate. Large suitcases are wire-locked in the stroller area, and no bags are allowed in the artworks.
• Child 4–12 is ¥1,500, junior and high school ¥2,800, and 3 and under free.

The full guide is on our teamLab Planets page.

Small Worlds (Ariake)

Sweet spot: ages 6 and up, plus parents who like models. It is one of the largest miniature museums in Asia, at around 7,000 m², with space, airport, city and Evangelion areas. Tickets are ¥1,700 for ages 4–11 and ¥2,100 for ages 12–17; 3 and under free. No tripods, selfie sticks or outside food. It is at Ariake-Tennis-no-mori Station, a few stops from Odaiba. See the Small Worlds page.

Free things for families

• Odaiba Beach: sand and a view of Rainbow Bridge. Swimming is prohibited, except in designated areas on the ODAIBA PLAGE event days in July. Paddling at the water’s edge is allowed. See Odaiba Beach.
• Tokyo Aqua Symphony: the new fountain in Odaiba Marine Park, opened 28 March 2026. Free and no reservation needed. Under the normal schedule, shows run from 15:00 into the evening. Check the official calendar for your day.
• The Gundam Base Tokyo (DiverCity 7F): free entry, with model kits and displays. The life-size Unicorn Gundam statue outside ended its display on 31 August 2026, so don’t promise it. See Gundam Base.
• Fuji TV Hachitama (25F): not free, but cheap. Elementary and junior high students pay ¥500 and preschoolers are free. Closed on Mondays.

Miraikan, the science museum, is closed for renovation from 1 October 2026 to 22 April 2027 and reopens on 23 April 2027. Don’t build a family day around it inside that window. See Miraikan.

The rainy-day plan

Go to DECKS Tokyo Beach and stay there. LEGOLAND, Joypolis, Madame Tussauds and the Trick Art Museum are all inside, with the Haunted School and the Odaiba Takoyaki Museum for lunch. From DECKS, Aqua City (AniTouch) is a short walk, and DiverCity (Unko Museum, Gundam Base) is about five minutes on foot from Daiba, one Yurikamome stop away.

A simple wet-day order for a family with children aged 5 to 10:

1. LEGOLAND at opening, on an official timed ticket if it’s a weekend.
2. Lunch in DECKS.
3. Trick Art Museum on Seaside Mall 4F.
4. AniTouch in Aqua City for the late afternoon.

With older children, swap LEGOLAND for Joypolis on an Evening Passport and add the Unko Museum. Our itinerary page has full-day versions.

Getting around with children

On the Yurikamome, a one-day pass costs ¥410 for a child and ¥820 for an adult, and it pays off quickly if you are hopping between Toyosu, Ariake and Odaiba. The Tokyo Subway Ticket does not cover the Yurikamome or the Rinkai Line. More in getting to Odaiba.

If you are planning several paid stops, Klook Pass Greater Tokyo lets you choose from a list that includes LEGOLAND, Joypolis, Madame Tussauds and the Unko Museum.
