“It’s our big Tokyo day… and the forecast says rain.”
“Is there a full-day plan where the kids won’t get soaked — or bored?”
Good news: this is exactly when the Odaiba & Toyosu bay area shines. Some of Japan’s best indoor attractions — teamLab Planets, LEGOLAND Discovery Center, Tokyo Joypolis — are lined up along one driverless train line. Honestly? This area is better on a rainy day. 🐻
I’m Travel Mama Bear, a mom living in Japan. This guide gives you a stroller-friendly, indoor-focused 1-day itinerary for Odaiba & Toyosu — with age guides for each spot and the one trick that makes the whole day work: booking your tickets in advance.
Note: I haven’t visited Toyosu and Odaiba myself yet — this guide is based on official sources and reviews from other families, researched carefully with a stroller-and-toddler lens.

👇 The short answer! 👇
⏳ In a hurry? These are the 3 hotels that make this rainy-day plan work.
The bay area’s spacious family rooms sell out first on weekends and holidays. The smartest move: lock in a free-cancellation rate now, then plan the details later.
👑 Hilton Tokyo Odaiba (for the night view) — every room has a balcony over the bay, and kids 5 and under sleep free 🌉
＼ Bay-view rooms go first ／
👑 La Vista Tokyo Bay (for access) — a 1-minute, stay-dry walk from Yurikamome Ichiba-mae Station, with a famously good breakfast buffet 🍳
＼ A 1-minute walk from the station ／
👑 Tokyo Bay Ariake Washington Hotel (for value) — family rooms plus a coin laundry, so luggage stays light on longer stays 👕
＼ The value pick in the bay area ／

🚉 Getting to Toyosu from Central Tokyo
The day starts at teamLab Planets in Toyosu. Here’s how to get there from where most families stay:
- From Tokyo Station: Yurakucho Line from Yurakucho Station (a short walk from Tokyo Station) to Toyosu — about 15 min, then a 10-min walk or 1 stop on the Yurikamome to Shin-Toyosu
- From Shinjuku / Shibuya: Take the JR Yamanote Line to Shimbashi, then the Yurikamome all the way to Shin-Toyosu — about 45–55 min total, and you get the full bay-crossing ride as a bonus
- From Asakusa / Ueno: Ginza Line to Shimbashi, then the Yurikamome — about 40–50 min
- From Tokyo Disney Resort area: JR Keiyo Line to Shin-Kiba, then Yurakucho Line to Toyosu — about 25 min
💡 Every route above has elevators at each transfer. If you’re not sure, Google Maps works well in Japan and shows elevator-friendly routes.
🚝 How to Get Around — The Yurikamome Line
- One train line does it all: the Yurikamome connects Shin-Toyosu to Odaiba-Kaihinkoen and every stop in this itinerary. Every station has elevators — stroller-friendly all the way
- How to pay: Tap your Suica or PASMO IC card, or tap a contactless credit card (Visa, Mastercard, etc.) at the gate — no ticket needed. Tapping a credit card automatically caps your fare at the 1-day pass price, so there’s no need to buy a pass. A QR 1-day pass (¥820 adult) is also available online
- Kids ride cheap: Children under 6 ride free (up to 2 per paying adult), and ages 6–11 pay half fare. A family of four with two preschoolers pays for just two adults
- Grab the front seats! The Yurikamome is fully automated with no driver — sit at the very front and your kids get a panoramic “driver’s view” of Rainbow Bridge and Tokyo Bay. The ride itself becomes an attraction
- Stations connect to malls via covered decks — a few short open-air stretches exist, so a compact umbrella and a stroller rain cover keep everyone dry
- Every mall has nursing rooms & changing tables — Aqua City, DECKS, and LaLaport Toyosu are all well equipped
☔ Rainy-day Japan, decoded:
- Forgot an umbrella? Every convenience store sells clear plastic ones for ¥500–800. Kid-size umbrellas are there too
- Those plastic sleeves at every entrance are for your wet umbrella — slide it in so you don’t drip inside. Malls and museums all have them
- Umbrella stands with locks are common at attractions. Take the key tag, and don’t worry — umbrella theft is rare in Japan
- Stroller rain covers are hard to find on the day — bring one from home if you can
You’ll rely on your phone all day — Google Maps navigation, real-time train info, attraction wait times, and messaging when your group splits up. We used Airalo Japan eSIM on our family trip and it activated the moment we landed at the airport. No SIM card swap, no standing in line at the airport counter.

🗺️ Itinerary Map
🐻 Travel Mama Bear says: “Blue pins are attractions, yellow pins are family hotels — tap each one for details!”
🌀 9:30 — teamLab Planets TOKYO (Toyosu)
The world-famous “museum you walk through water.” You explore barefoot, wading through knee-deep water and mirror-floored light installations. Completely indoors — the rain simply doesn’t exist in here. The first slots of the morning are the least crowded.
- 🦶 Everyone goes barefoot — some areas have knee-deep water. Bring a change of clothes and a small towel for kids (lockers available)
- 👗 Mirror floors — wear pants rather than skirts (wrap-skirts can be borrowed on site)
- 🚼 Strollers are stored at the entrance — a baby carrier works best inside
- 💴 Price guide: Adults from around ¥3,800–4,200 (pricing changes by date), ages 4–12 ¥1,500, under 3 free. Weekends and peak dates cost more
- ⏱ Time needed: about 1.5–2 hours
- 🚉 Access: 1-min walk from Shin-Toyosu Station (Yurikamome) / 10-min walk from Toyosu Station (Metro)
🐻 Travel Mama Bear says: “If your little one is still in diapers, pack waterproof diapers and a full change of clothes — the water areas are the highlight, and kids will NOT want to skip them!”
🎨 teamLab Planets: Book Your Timed-Entry Ticket in Advance!
teamLab Planets uses a timed-entry system, and rainy days and weekends often sell out. Once your travel dates are set, lock in your slot early 🐻
- Enter with your smartphone — no printing needed
- Book a morning slot to beat the crowds
- Fully bookable in English

🍱 12:00 — Lunch: Senkyaku Banrai or LaLaport Toyosu
Two great options right after teamLab. Want the full Japanese experience? Head to Toyosu Senkyaku Banrai — an Edo-period-style food street next to Toyosu Market, with point-and-order street food (seafood skewers, wagyu sushi, matcha sweets) and a free rooftop footbath on the 8th floor. Want guaranteed seats and baby facilities? LaLaport Toyosu is directly connected to the station, with nursing rooms and plenty of reservable restaurants. Both are fully indoor.
💴 Bring some cash for Senkyaku Banrai. Many of the street-food stalls accept cards or IC cards, but some are cash-only — and a few thousand yen in your pocket means the kids never have to skip the thing they want. LaLaport’s restaurants all take cards.
For the full breakdown of the 9 best family-friendly restaurants in this area — with stroller access, kids’ menus, and reservation links — see our dedicated guide 👇
⚠️ Give KidZania Tokyo Its Own Day
Yes, KidZania Tokyo is inside LaLaport Toyosu — and yes, it’s wonderful. But it burns an entire day of kid-energy all by itself. It doesn’t fit into this one-day loop — give it its own dedicated day.
🐻 Our honest fail story (KidZania Koshien — kids aged 6 & 4)
We did the evening session as a day trip — the kids played flat-out until 9 PM, and the parents hit their limit long before the kids did. If you’re coming from farther away, staying nearby — or staying the night before and doing the morning session — is the smarter play.
One more tip: things stay peaceful with one adult per child.We split up — Dad with our eldest, Mom with our youngest — and had zero “I want to do THAT one!” sibling battles.
＼ Book early once your date is set ／
For a KidZania day, staying overnight was the right call — and the 3 bay-area hotels at the top of this article are perfect for it 🐻
👉 More KidZania details — the food options inside, English Wednesdays, and ticket types — are in our Toyosu & Odaiba lunch guide.
🚢 14:00 — Yurikamome to Odaiba | Aqua City
After lunch, hop on the Yurikamome to Odaiba-Kaihinkoen Station. Race the kids to the front seats — the driverless ride over the bay is a mini-attraction in itself 🚝
- 🗽 If the rain pauses: snap a family photo with the Statue of Liberty replica and Rainbow Bridge behind you
- 🤖 Gundam fans, read this first: the life-size Unicorn Gundam statue was permanently removed on 31 August 2026. The Gundam Base Tokyo store is still open and fully indoor — full details just below
- 🌧 If it’s pouring: go straight into Aqua City Odaiba — a huge all-weather mall with a cinema, food court, and Toys”R”Us
- ☕ Break time: Eggs ‘n Things (inside Aqua City) and bills (next door in DECKS Tokyo Beach 3F) both welcome strollers inside, with bay views and famous pancakes
- 🚼 Nursing rooms and baby facilities available
🤖 Gundam in Odaiba: What Changed in 2026
After nearly nine years outside DiverCity Tokyo Plaza, its exhibition ended on Monday, 31 August 2026, according to the official Unicorn Gundam Statue website. Many guidebooks and older blog posts still send you there to watch it transform — it is no longer standing.
Official Unicorn Gundam Statue site (English) →
The good news for a rainy day: THE GUNDAM BASE TOKYO is still open, and it was always the better stop when the weather turns. It is entirely indoors, on the 7th floor of DiverCity Tokyo Plaza, about a 5-minute walk from Aqua City.
- Where: DiverCity Tokyo Plaza, 7F
- Hours: 11:00–20:00 on weekdays, 10:00–21:00 on weekends and holidays
- Inside: a huge official Gunpla shop, large-scale model displays, and Gundam Base exclusive kits you will not find at home
- Cost: free to enter — you only pay for what you buy
Entry is free, but it is not always walk-in. On Fridays, Saturdays and Sundays the Tokyo store runs an advance entry lottery, and applications close roughly one to two weeks before the date — checking on the morning of your visit is far too late. Applying needs an Apple account and a Google account, and winners may be asked for photo ID that matches the name on the application.
On other days you can usually walk in, but when it is busy the store hands out numbered tickets, and on the busiest days it may stop letting anyone else in for the rest of the day. The build room is also suspended for the time being.
If your child has their heart set on it, check the official Gundam Base site while you are still planning the trip, not after you land.
Official site. Japanese only, so use your browser’s translate function. This is not an affiliate link.
If your children are too young for model kits, DiverCity still earns its place on a wet afternoon: the food court on 2F is large, stroller-friendly and takes no reservations.
💩 Unko Museum Tokyo — a Poop Museum, and Kids Adore It
💩 One more DiverCity ace, also on the 2nd floor: the Unko Museum Tokyo. “Unko” means poop — and this candy-colored museum of poop-themed games, neon photo spots and a “shout unkoooo!” ritual at the door reduces elementary schoolers to helpless giggles. Fully indoor, takes about 1–2 hours, tickets from around US$13. Entry is by timed web ticket, so book a slot before you go.
- Where: DiverCity Tokyo Plaza 2F — 3 min from Tokyo Teleport Station (Rinkai Line), 5 min from Daiba Station (Yurikamome)
- Price: from ¥2,000 adults, ¥1,500 junior and senior high school, ¥1,100 children aged 3 and over. It changes by date
- Age rule: no age limit, but children under 7 must be with someone aged 13 or older
- Last entry: one hour before closing
- How long: most families spend 1 to 2 hours
The official site says day-of tickets are limited and recommends buying online in advance. Slots for busy afternoons do sell out, so pick your time slot before you leave the hotel rather than turning up and hoping.

🎠 16:00 — DECKS Tokyo Beach: LEGOLAND & Joypolis

🧩 LEGOLAND Discovery Center Tokyo (Best for Ages 3–10)
- An indoor LEGO wonderland — rides, a 4D cinema, build zones, and a giant LEGO diorama of Tokyo
- ⚠️ Adults cannot enter without a child — it’s genuinely built for kids
- 💴 Price guide: Tickets are online-only, from around ¥2,350 depending on date and time — there are no same-day tickets at the door, so book before you go. Ages 2 and under free
- ⏰ Check last entry before you go — it varies by day and can be as early as 16:00. Aim to arrive by 15:30 to be safe
- ⏱ Time needed: about 2 hours
👉 On rainy days, families flood the indoor spots — with an advance ticket you skip the line and walk straight in
🧩 Check LEGOLAND Tokyo Tickets on Klook(instant e-ticket on your phone)
🎢 Tokyo Joypolis (Best for Elementary Schoolers & Up)
- One of Japan’s largest indoor amusement parks — 20+ attractions including a spinning coaster, VR rides, and 3D experiences
- ⚠️ Many rides have height restrictions — preschoolers can only ride a limited selection. Best for elementary-age kids and thrill-loving parents
- 💡 Kids far apart in age? Some families split up: older kids to Joypolis, younger ones to LEGOLAND — both are in the same building
- 💴 Price guide: Passport (entry + all rides) ¥6,000 adults / ¥5,000 school-age kids; from 15:00 the Evening Passport is ¥5,000 / ¥4,000 — check Klook for current pricing. Preschoolers enter free but pay per ride. Height limits are posted in cm; most thrill rides need 120–130 cm (about 47–51 in)

- Kids’ amenities, pool, and spa — a family favorite
- The Seascape Terrace Dining buffet makes family dinner easy (something for every picky eater!)

❓ Frequently Asked Questions
- QDoes this itinerary really work in the rain?
- A
Yes. teamLab Planets, the Unko Museum, LEGOLAND and Joypolis are all indoors, and the whole route runs on one train line. The only exposed parts are short connecting decks between stations and malls.
- QIs it worth doing with a toddler under 3?
- A
Yes, with two caveats: watch the water areas at teamLab Planets, and Tokyo Joypolis has few rides small children can board. The age guide breaks down every stop.
- QCan we do the whole day with a stroller?
- A
You can. Every Yurikamome station has a lift, and Aqua City, DECKS and LaLaport Toyosu all have nursing rooms and changing tables. Bring a stroller rain cover, because a few connecting decks are not covered.
- QDo we need to book teamLab Planets in advance?
- A
Yes, book a timed ticket before you go. Same-day tickets sell out. With a ticket bought in advance you just show your phone at the entrance.
- QCan we still see the life-size Gundam in Odaiba?
- A
No. The life-size Unicorn Gundam statue at DiverCity Tokyo Plaza ended its exhibition on 31 August 2026. The indoor Gundam Base Tokyo store is still open, but on Fridays, Saturdays and Sundays entry runs on an advance lottery.
- QWhat ages is the Unko Museum good for?
- A
It lands best with ages 4 through elementary school. Children under 3 enter free, and from age 3 there is a charge. There is no age limit, but under-7s must be with someone aged 13 or older.
- QWhere should we stay for this itinerary?
- A
Staying in the bay area saves you the evening train ride with tired children. Hilton Tokyo Odaiba is the anchor hotel on this route, and family rooms across the bay area fill up on weekends and holidays, so hold a free-cancellation rate early.
