What makes it 70% Kids-Friendly: Kids aged 3-12 can splash in bubbly pools, watch big-screen TV and read comics, but stone spa is banned, gender separation starts at 7, and there is no playground, so parental guidance is vital.
Why 2-3 hours visit duration is ideal for with kids: 2-3 hours is enough for bathing, relaxing, and a meal without tiring younger kids.
Family Bathing:
Soak together in large indoor baths with hydro-jets and reclining tubs.
Tip: Visit early to try the bubble bath before it gets busy.
Viewing Spa:
Enjoy carbonated water with a big-screen TV in the pool area.
Tip: Pick a show that kids love to keep them engaged during the soak.
Reading & Sun Deck:
Browse manga in the lounge or get fresh air on the rooftop deck.
Tip: Grab a comic from the manga library while kids rest on recliners.
Meal at Restaurant Yurari:
Eat simple Japanese and Western dishes with kids' portions.
Tip: Order curry or soba for kids; share rice dishes to taste more flavors.

Just spent 3 hours, before our flight home. Loved it! The staff was super friendly and helpful. It was our first time to an onsen. Not as English friendly as other places in Tokyo but we made it through just going with the flow and asking for help. Lots of free luggage storage. Had lunch. Just pay for everything with your wristband. Husband got great massage too. Would like to go back some day.

The experience was excellent and comparing with another onsens, this one can ...

This was within walking distance from my hotel. I visited twice during my vacation and enjoyed both times. The water is the perfect temperature, staff was helpful and polite. I had an amazing visit both times. The only issue I had at all was that this was the one place in Japan with machines that didn't like my US credit cards so had to pay in cash.

I always stop relaxing at Heiwajima Onsen while a long wait for my next flight. This place is perfect for hanging out if you don’t want to explore downtown. The facility includes shower, onsen, sauna, steam room, restaurant, snack shop, spa for fee, relaxing room and tv room. I landed at Haneda at 6AM and spent 7 hours at the onsen for late afternoon flight. How to get there: Use Keikyu line at ...

Do you have an extended layover in Tokyo? Then this is a great place to stay and wash up for your overnight needs. After walking around for 2 hours in the Tokyo summer humidity a nice bath felt amazing and relaxing. The water temp is nice and hot. And compared to plane seats, you will get an amazing night sleep in the relaxation lounge (though you might need some ear plugs and an eye mask if you s...
In winter, outdoor pools feel extra warm against cold air. In summer, use the sun deck and cool off in the lounge.
