Introducing Mashimiruku Wooden Toy Café for Babies
Hi there! It’s Kurubushi, your friendly writer from Sarukuma ☆彡
Today we’re heading to Koike, Mashiki Town, Kamimashiki District
to visit Mashimiruku — the Wooden Toy Café for Babies!
Mashimiruku is an indoor playground that opened in June 2017,
curated and supervised by the Tokyo Toy Museum, and built right alongside the Green Hill Mashiki group home.

The lush pine tree partly blocks the view, but Green Hill Mashiki is a residential facility for elderly residents,
which means staff and people are around 24 hours a day, 365 days a year.
And because of that, the play space is open 365 days a year, too!
Whether it’s blazing hot, freezing cold, or you’re back home visiting family with no idea where to take the kids,
Mashimiruku is always open — that’s the magic of it.
And what’s more — it’s completely free, and every single toy is a carefully chosen wooden toy.
This honestly feels too good to be true…
Is there really any reason NOT to go?

There’s a wide, gentle slope leading up to the entrance.
Strollers can roll right in with zero stress! ☆
The parking lot doesn’t have painted lines, but you’re free to park there.
Since facility staff and residents come and go, it’s a good idea to avoid parking right near the slope.

There’s also a vending machine on site ^^
So if you forgot your water bottle, no worries!

When the café first opened, there used to be intergenerational events,
but those aren’t currently being held.
With nuclear families becoming the norm and fewer chances for kids to interact with elders,
I’d love to see them come back someday…

Opening hours are 10:00 AM to 4:00 PM.
To keep things safe and comfortable for babies and small children, the space is intended for kids up through the lower grades of elementary school.
Closed Tuesday afternoons for maintenance.
Occasionally there are temporary closures when Green Hill Mashiki hosts its own events,
so it’s a good idea to check the Green Hill Mashiki Facebook page for the latest updates before heading over ○
Eating inside the playroom isn’t allowed, but staying hydrated absolutely is.

Right next to the play area there’s a diaper-changing bed — super convenient ^^

The restroom is roomy enough to comfortably take little ones in with you.
And there’s even a child-sized toilet seat — such a lifesaver!

Just a heads up — used diapers go home with you.
Following the simple rules and being a good guest is what helps a wonderful place like this stay open for everyone ^^

When you walk in, there’s a sign-in sheet — just write your name and you’re set ♪
What Makes Mashimiruku Special
Being open year-round is a huge plus, of course,
but the real magic is that EVERY toy here is wooden!!!
There were toys I’d never seen before, and honestly,
I was even more excited than my kids!

Of course, the famous KAPLA wooden planks are here too (my kids absolutely love these!)

Spinning tops and balance-style board games, too.

This balance game is all about stacking up a cactus.
The rules are simple, so even pre-kindergarten kids can join in and have a blast ^^

Beyond the 3D puzzles,
there are even handmade puzzles featuring scenes from across Kumamoto ^^

There’s a tap-tap-tap carpenter playset, too ^^
My son became obsessed with tools around age 2,
and he happily hammered away at this one for ages.

This one is similar to a xylophone.
So many toys I’d never seen before — endlessly fascinating!

There’s also a tatami-mat corner — perfect for tiny babies who aren’t crawling yet ♪
And tons of building blocks, so kids can build to their hearts’ content.

Because the blocks are all the natural color of wood, they leave plenty of room for kids’ imaginations to fill in,
which makes pretend play even more open-ended ^^

You’ll find blocks in every size — big, small, and everything in between!
And yes — there’s even a wooden ball pit ^^

It’s surprisingly spacious, and your kids are guaranteed to lose their minds (in the best way).

The wall decorations are magnetic, so kids can stick them on and peel them off,
letting their imagination roam freely.

There are also non-wooden toys for active play,

plus educational toys.

Oh, and there’s an aquarium in the room too, with goldfish swimming inside ^^
Just watching the goldfish drift around is so soothing.
Tucked away in the peaceful countryside of Mashiki Town,
this is a truly wonderful spot to nurture your children’s curiosity and creativity. Why not pay a visit? ^^
Oh! And it’s also a fantastic place to bring grandkids when they come home for New Year’s or the Obon holidays!
It’s not just for moms and dads — grandmas and grandpas, take note ♪
