What makes it 65% Kids-Friendly: Children over 3 enter for ¥1,000, get towels, enjoy bubbly pools and big-screen baths under adult watch, but hot-stone spa is barred, no play room exists, and constant supervision is mandatory.
Why 3–4 hours visit duration is ideal for with kids: Allows time for bathing, relaxing in the lounge, and a family meal without rushing young children.
Family Natural Bath:
Share the hydro-jet whirlpool and reclining onsen pools together.
Tip: Bring swim diapers only for the small baby tubs; older kids must shower before entering.
Viewing Spa with TV:
Soak in the carbonated bath while watching a big-screen program.
Tip: Pick a corner seat early to get the best view of the TV.
Manga Library & Lounge:
Browse over 10,000 comics in reclining chairs.
Tip: Let older kids pick their favorite title while adults rest.
Rooftop Sun Deck:
Enjoy fresh air and city views between baths.
Tip: Head up right after a hot soak to cool off and stretch.
Restaurant Yurari:
Order children’s portions of curry or soba after your soak.
Tip: Visit before 6 pm to avoid dinner rush and noisy crowds.

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, the hot springs feel extra soothing against the chill. In spring and autumn, the rooftop deck breeze is perfect. In summer, skip the midday sun by using the sun deck early or late.
