Rainy day in Tokyo? Or is it simply too hot to spend another full afternoon walking outside with young children?

Tokyo has plenty of indoor attractions, but the best choice for a baby is very different from the best choice for a six-year-old.

I’m a Japanese mom living in Tokyo with two young children. I’ve personally visited ASOBono!, Sanrio Puroland, and teamLab Planets with my family, so I’ll share the practical details I care about as a parent — crowds, strollers, baby carriers, food and how tiring the day actually feels.

For the other places, I’ve included options I think are genuinely useful for visiting families rather than pretending I’ve personally tried every attraction in Tokyo.

Quick Answer: Where Should You Go?

If you only have 30 seconds, start here.

Traveling with a baby:
→ ASOBono! or Sumida Aquarium

Traveling with a toddler:
→ ASOBono! or Sanrio Puroland

Traveling with a 4–6-year-old:
→ Sanrio Puroland, teamLab Planets, LEGOLAND Discovery Center or KidZania

Traveling with an active older child:
→ KidZania or Tondemi

Need somewhere easy with a stroller:
→ ASOBono! or Sumida Aquarium

Want a full indoor day:
→ Sanrio Puroland or KidZania

Want something adults will enjoy too:
→ teamLab Planets

Everyone is already tired:
→ Sumida Aquarium + Tokyo Solamachi

Here’s why.

1. ASOBono! — My Top Pick for Babies and Toddlers

Best for: Babies, toddlers and preschoolers
Area: Tokyo Dome City
Choose it if: You want an easy, low-stress indoor day

If I were visiting Tokyo with a baby or toddler on a rainy day, ASOBono! would be one of my first choices.

I’ve been here with my children, and it feels genuinely designed for families with small kids rather than being an adult attraction that happens to allow children.

There is a separate play space for babies, which is especially useful when you have a crawling child and do not want bigger kids running around them.

It is also inside Tokyo Dome City, and this makes the whole day much easier.

There are plenty of family-friendly places to eat nearby, so once the kids finish playing, you do not need to start another complicated journey just to find lunch.

Local Mom Tip: Go on a Weekday

This is the part I would emphasize most.

Weekends can get very crowded.

If your itinerary is flexible, I would choose a weekday.

When the one-day child pass is available, I also like that option because small children can easily spend hours here. It is much more relaxing than constantly watching the clock.

Check the current ticket options before your visit because ticket types and availability can vary.

2. Sanrio Puroland — Best for Character-Loving Preschoolers

Best for: Toddlers, preschoolers and younger elementary-school kids
Area: Tama Center
Choose it if: Your child loves Hello Kitty, Cinnamoroll, My Melody, Kuromi or Sanrio

Puroland is a very easy rainy-day choice because the main experience is indoors.

I’ve visited with my children, and I think young Sanrio fans can happily spend most of the day here.

But parents with babies should know one thing:

Bring a baby carrier.

You can arrive with a stroller, but in my experience, a stroller is not always the easiest way to move around Puroland.

If you have a child who cannot walk for long periods — or who may fall asleep halfway through the day — I would not visit without a carrier.

That small decision can make the difference between a fun afternoon and carrying a sleeping child in your arms for an hour.

If stroller logistics are important for your trip, read my separate guide to Tokyo with a Stroller.

Local Mom Tip: Make Puroland the Main Event

Puroland is not in central Tokyo.

I would not schedule a packed morning somewhere else, travel to Puroland, and then expect young children to continue sightseeing afterward.

Make this the main attraction of the day and keep the rest flexible.

3. teamLab Planets — Best for the Biggest “Wow” Factor

Best for: Preschoolers, school-age kids and adults
Area: Toyosu
Choose it if: You want an experience parents and kids can enjoy together

I took my older daughter to teamLab Planets when she was four, and she loved it.

The huge spaces, lights, water, mirrors and interactive installations are completely different from a traditional museum.

It is also extremely popular with international visitors, so I would not treat it as something you can always decide to visit at the last minute.

Important: No Strollers Inside

This is probably the most important parent detail.

You cannot take a stroller through teamLab Planets.

If you are traveling with a baby or a child who cannot comfortably walk through the experience, bring a baby carrier.

For us, age four was a great age for it.

For a non-walking baby, it becomes a very different experience because the parent will be carrying the child.

Local Mom Tip: Book First, Plan Toyosu Second

I would secure your teamLab time before planning the rest of the day.

Once you know your time slot, you can build meals or other Toyosu activities around it.

Check current teamLab Planets ticket availability on Klook.

4. KidZania Tokyo — Best for Kids Who Want to Actually “Do” Something

Best for: Preschoolers and school-age children
Area: Toyosu / LaLaport Toyosu
Choose it if: Your child loves pretend play and role-playing

KidZania is very different from simply looking at an aquarium or museum.

Children enter a miniature city and try different jobs and activities.

For the right child, this can easily become the main event of the day.

It is also particularly interesting for overseas families because there are English-language options, including an English Premium Tour available through Klook.

A Practical Parent Detail People Often Miss

KidZania is inside LaLaport Toyosu.

That makes the location much more useful to families than the attraction alone might suggest.

There are coin lockers for baggage, and LaLaport also has Akachan Honpo, which is extremely useful if you suddenly need baby food, diapers or other kids’ supplies.

There is also DAISO for inexpensive everyday items.

When traveling with children, I love places where one destination solves several problems at once.

Who Should Skip It?

If you have a baby or very young toddler, I would choose ASOBono! or the aquarium instead.

KidZania becomes much more valuable once the child is old enough to understand the idea of choosing activities and participating.

For international families, check KidZania Tokyo and English-language ticket options on Klook.

5. Sumida Aquarium + Tokyo Solamachi — Best When You Want an Easy Day

Best for: Babies through elementary-school kids
Area: Tokyo Skytree Town
Choose it if: Your family is tired

This is the option I would choose when nobody needs a huge once-in-a-lifetime attraction.

Sometimes you just need the day to be easy.

Sumida Aquarium is indoors, and being inside Tokyo Skytree Town means food, shopping and places to rest are already nearby.

That is especially valuable with a baby.

You can see the aquarium, have lunch, take a break, and decide afterward whether everyone still has enough energy for anything else.

You do not have to turn every day in Tokyo into a sightseeing marathon.

For families with small children, fewer transfers often make the day much better.

6. LEGOLAND Discovery Center Tokyo — Best for LEGO-Loving Kids

Best for: Preschoolers and younger elementary-school kids
Area: Odaiba
Choose it if: Your child wants to play rather than just look

LEGOLAND Discovery Center is a useful indoor option when children need some proper hands-on play.

I would especially consider it after several sightseeing-heavy days.

Temples, trains and famous neighborhoods may be fascinating to adults, but sometimes a child simply needs a few hours to build, play and move around.

Odaiba also gives you plenty of other indoor options nearby, so you can keep the day flexible rather than crossing Tokyo again after one activity.

7. Tondemi Heiwajima — Best for Kids With Energy to Burn

Best for: Active kids
Area: Heiwajima
Choose it if: Your child needs to jump, climb and MOVE

This is the opposite of a calm museum day.

I would consider Tondemi for the child who has spent several days walking politely around Tokyo and now desperately needs physical activity.

It has different areas for active play, and this is one place where I would check the current age, height and weight requirements before building your day around it.

That matters especially when traveling with siblings of different ages.

Do not assume every child in your family will be able to use the same areas.

For the right child, though, this could turn a rainy afternoon into one of the most fun parts of the trip.

8. SMALL WORLDS — Best for a Calmer Indoor Afternoon

Best for: Preschoolers and school-age kids
Area: Ariake
Choose it if: You want something slower and quieter

SMALL WORLDS is a miniature museum and is a useful option when your family wants to stay indoors without another highly stimulating attraction.

Compared with KidZania or Tondemi, this is a much slower-paced experience.

That can actually be a benefit.

Planning to visit SMALL WORLDS? Check current ticket options on Klook.

Tokyo trips are exciting, but young children can get overstimulated quickly.

Not every day needs crowds, flashing lights and a packed itinerary.

If you are traveling with a baby, I also recommend carrying a few diaper disposal bags whenever you go out in Tokyo.

And if you suddenly run low on baby supplies, see my guide to where to buy diapers and baby food in Tokyo.

What I Would Choose by Age

Baby

ASOBono! would be my first choice.

If the adults also want to sightsee, I would choose Sumida Aquarium + Solamachi.

Toddler

ASOBono! for play.

Puroland if they already recognize and love Sanrio characters.

Ages 4–6

This is where the choices get really good.

I would look at:

• teamLab Planets
• Sanrio Puroland
• LEGOLAND Discovery Center
• KidZania

My daughter loved teamLab at four, but personality matters more than rankings.

A child who loves characters may prefer Puroland.

A builder may prefer LEGO.

A child who constantly plays “shop,” “doctor,” or “teacher” may love KidZania.

Older or Very Active Kids

Start with KidZania or Tondemi.

SMALL WORLDS can be a good option if you want something calmer.

My Rainy-Day Strategy as a Tokyo Mom

I would not book five backup attractions “just in case.”

Instead:

Book one must-do attraction in advance.

For example, if teamLab or Puroland is important to your family, secure that first.

Then keep one easy option in mind that does not require an elaborate itinerary.

And most importantly:

Do not cross Tokyo three times just because it is raining.

Choose one area.

If you are in Toyosu, stay around Toyosu.

If you are at Tokyo Dome City, enjoy the area around Tokyo Dome City.

If you are at Skytree, let Solamachi and the aquarium become the day.

With children, saving energy is often more valuable than adding one more attraction.

Final Thoughts

The best indoor attraction in Tokyo is not necessarily the most famous one.

It is the one that matches:

• your child’s age
• their personality
• whether they can walk
• whether you have a stroller
• how tired everyone already is
• how much traveling you want to do that day

For babies and toddlers, I would prioritize ASOBono! and Sumida Aquarium.

For preschoolers, Puroland, teamLab and LEGOLAND give you very different experiences.

For older kids, KidZania and Tondemi become much more interesting.

And if everyone is tired?

Pick the easiest option.

You do not need to “win” Tokyo by visiting the most attractions.

A relaxed day where your child is actually having fun is usually the better family memory.
