Spa Resort Hawaiians
SaveAn indoor resort of pools and hot springs, kept at summer temperature all year.
The hot springs run at 3.5 tons a minute, among the largest single-site uses in Japan.
MoreWhat kind of place
Spa Resort Hawaiians puts pools, hot springs, a Polynesian song-and-dance show, and four hotels on grounds the size of six Tokyo Dome stadiums.
The buildings are kept at summer temperature all year, so people walk around in swimsuits in the middle of winter.
The springs deliver 3.5 metric tons of water a minute, about 925 gallons, at 137°F (58.1°C) — one of the largest volumes drawn by any single facility in Japan.
Sources and evidence (26)
- There are four places to stay on site: Monolith Tower, Hotel Hawaiians, Wil Port, and Mauna Village.source
- The children's pool zone, Wai Wai Ohana, includes a baby pool called Tenshi no Mizuba that can be used in swim diapers.source
- Children in diapers can still walk around the poolside and put their feet in the shallows.source
- In the hot spring baths, where you bathe without a swimsuit, there is no such restriction on children in diapers.source
- Wai Wai Ohana has a nursing room and a diaper changing space.source
- The baby pool is 4 inches (10 cm) deep, with the water at 88 to 97°F (31 to 36°C).source
- The toddler pool is 20 inches (50 cm) deep, with the water at 84 to 88°F (29 to 31°C).source
- Pool water is set at 86°F (30°C), with about a degree of variation either way.source
- The women's bath at Edo Jowa Yoichi is out of service from September 24 to December 21, 2026, and during that period men and women use it in alternating slots.source
- The children's pool is closed from Monday, March 1 to Friday, March 5, 2027.source
- The Hula Museum has been closed since November 10, 2025, with no reopening date announced.source
- Routes through the building for wheelchairs and strollers are laid out on a barrier-free map, handed out as a Japanese-language pamphlet.source
- Lockers run 200 to 300 yen for the single-use type and, in practice, 300 to 400 yen for the kind you can open and close as often as you like, cash only, and anything too big for a locker is held for 600 yen per item.source
- Check-in is 2:00 p.m. at Monolith Tower, Hotel Hawaiians, and Wil Port, and 3:00 p.m. at Mauna Village, with checkout at 10:00 a.m. at all four.source
- To have baby bottles washed and sterilized, ask the hotel front desk staff.source
- Children 3 and up get their own amenities: sandals in a single size (20 cm, about 8 inches long) and indoor wear in S for heights of 35 to 43 inches (90 to 110 cm), M for 43 to 59 inches (110 to 150 cm), and L above 59 inches (150 cm), plus thin gowns in 43-inch and 55-inch sizes (110 cm and 140 cm) lent out from about November through May.source

- The official website switches between Japanese, simplified Chinese, traditional Chinese, Korean, English, and French.source
- Two kinds of spring water come up here, sulfur and chloride, at 137°F (58.1°C) and mildly alkaline at pH 8.1.source
- The springs deliver 3.5 metric tons of water a minute, about 925 gallons, among the largest amounts drawn by a single facility in Japan.source
- The pounding-water bath and cypress bath at the large bathhouse Palace, and the Yunodake bath at Hotel Hawaiians, run sulfur spring water straight through rather than recirculating it.source
- The hot springs are presented as a pair: a large open-air bath with an Edo-period feel (Edo Jowa Yoichi) and a large bathhouse with a range of baths (Palace).source
- A show presents the traditional culture of Hawaii and Polynesia through live music and dance.source
- The building is kept at summer temperature year-round, so a swimsuit or T-shirt is enough, though a few areas run cooler and something to throw on helps.source
With kidsThe part that matters
A child still in diapers can get into the baby pool in the children's zone, Wai Wai Ohana — 4 inches (10 cm) of water held at 88 to 97°F (31 to 36°C), where swim diapers are fine.
It is the only pool open to them, and the hot springs you enter in a swimsuit are closed as well, but they can still walk the poolside and put their feet in the shallows, and the regular baths, where you bathe undressed, have no such rule.
Wai Wai Ohana also has a nursing room and a diaper changing area, and the Water Park front desk holds your stroller for free, so you are not pushing it past the steps that remain in places around the building.
The water slides cost extra and turn away anyone under 47 inches (120 cm), so with small kids you can skip that ticket and keep the money.

By age0-1 / 2-3 / 4-6
- Ages 0-1Even a child still in diapers can get into the baby pool Tenshi no Mizuba, in the Wai Wai Ohana children's pool zone, by wearing swim diapers. It is 10 cm deep at 31-36C, and the whole building is held at summer warmth all year, swimsuit weather indoors. The naked hot-spring baths carry no diaper restriction at all.A child who wears diapers day to day may not use the pools or the swimsuit hot springs other than Tenshi no Mizuba - walking the poolside and dipping feet in the shallows is fine. The nursing room and the diaper-changing space are both in Wai Wai Ohana. Strollers are checked free at the Water Park front desk, and you may drive to the entrance, unload, then park. If you stay over, ask when booking for the bed guard, formula-water pot, bed-wetting pad or child toilet seat (limited numbers), and the hotel front desk will wash and sterilize bottles.
- Ages 2-3Once out of diapers they can use the toddler pool: 50 cm deep, 29-31C. Rings and floats may be brought from home. If they are still in diapers, the day runs on Tenshi no Mizuba with swim diapers, the poolside, and the naked hot-spring baths instead.A child whose shoulders stay under the water when standing flat-footed may not swim without an adult in with them. Pool wear must be swimsuit fabric - no T-shirts - though rash guards and clothing sold for water use are fine. The building is summer-warm but a few areas run cooler, so something to throw on helps. Food and drink brought from outside are turned away.
- Ages 4-6One admission covers every pool and hot spring in Water Park, Spring Park, Edo Jowa Yoichi and Spa Garden Pareo. The Hawaiian and Polynesian show is live music and dance, watched from a seat. From age three there are child-size house robes (S, 90-110 cm) and sandals (20 cm) to borrow, so an overnight guest walks the resort in them.The three water slides (Mauna Black, Laki River, Kapuani Fall) and Big Aloha are closed to anyone under 120 cm. Until they reach it the toddler pool and the hot springs carry the day; once they do, add the separate slide pass - 2,800 yen for a three-slide day ticket, 3,000 yen from 1 July to 30 September. A child may enter the opposite-sex bath and changing room only up to age six and before school age; elementary students may not. The building is working toward barrier-free but steps and stairs remain in places, and the routes are shown on the barrier-free map.

Basics
- Fee：Prices move with the date — the resort uses variable pricing, and the fee calendar shows the adult admission for each day. The published base rates are ¥3,570 for an adult, meaning junior high school age and up, ¥2,250 for a child and ¥1,640 for a pre-schooler; in August 2026 the calendar's adult price ran ¥4,120 on ordinary days and ¥4,620 across the Obon week of 8-15 August. Arriving later costs less: ¥3,060 / ¥1,940 / ¥1,430 after 15:00 and ¥2,860 / ¥1,840 / ¥1,330 after 18:00. A disability or therapy certificate halves it to ¥1,785 / ¥1,125 / ¥820, shown at the ticket window. Admission covers the pools and hot springs of Water Park, Spring Park, Edo Jowa Yoichi and Spa Garden Pareo. The water slides are extra: a one-day pass for the three slides is ¥2,800 (¥3,000 from 1 July to 30 September), all four ¥3,500 (¥3,700), a single ride on Big Aloha ¥800 (¥900). Lockers, food, massages and rentals are also extra — a swimsuit set is ¥3,000 for a man, ¥5,000 for a woman and ¥2,000 for a child. Day parking for a standard car is free for the first two hours and ¥1,000 after that until midnight, though the FAQ words it differently — see the access notes.source
- Hours：Opening hours change day by day and are published on a calendar. Across August 2026 the resort opened at 09:15, 08:45, 09:30 or 10:00 depending on the date and closed at 22:00, with one day ending at 21:30; the hours can change at short notice, and individual facilities inside can change separately. It is not open every day of the year: the whole resort closes 25-28 January 2027. Outdoor bathing areas may close over the winter. The women's bath at the Edo Jowa Yoichi open-air spring is out of use from 24 September to 21 December 2026, with men and women alternating during that period, the children's pool closes 1-5 March 2027, and the Hula Museum has been closed since 10 November 2025.source
- Booking：Day tickets are sold online through the official calendar, where you pick the date and see that day's price. Staying overnight is the other way in: book through the official site and the admission ticket is included for every day of your stay — two days for one night, three for two. You can start playing before check-in time as long as you have done the paperwork at the front desk first. If you want the cribs and baby kit — bed guard, bottle-warming pot, step stool, bed pad, child toilet seat, diaper bucket — say so when you book, because there is a limited number of each.sourceOfficial site ↗
- Note: if your child is still in diapers, the only water they can get into is the baby pool Tenshi-no-Mizuba in Wai Wai Ohana — the other pools and the swimsuit hot springs are closed to them, though the naked hot springs are notsource

The indoor part is held at summer temperature all year, so swimsuits work in January. Two spring types feed it, sulfur and chloride, from a source at 58.1C, at 3.5 tons a minute. Pool water sits around 30C; the baby pool is 10cm deep at 31 to 36C. The hot springs come in two halves, a bath house called Palace and an open-air one, Edo Jowa Yoichi. Polynesian dance shows run with live music.
| Indoor / outdoor | Indoor & outdoor | The core of it is indoors and kept at summer temperature all year, so rain does not end the day. Some of it is outside — Spa Garden Pareo and the open-air Edo Jowa Yoichi — and outdoor bathing areas can close over the winter. | Web-checked | checked Aug ’26 | hawaiians.co.jp |
|---|---|---|---|---|---|
| Nursing space | Yes | In the children's pool zone Wai Wai Ohana, which also has a diaper-changing space. | Web-checked | checked Aug ’26 | hawaiians.co.jp |
| Diaper changing table | Yes | A diaper-changing space in Wai Wai Ohana, the children's pool zone. Worth knowing before you go: a child still in diapers can only get into one piece of water here — the baby pool Tenshi-no-Mizuba in that same zone, wearing swim diapers. Every other pool and every swimsuit hot spring is closed to them, even in swim diapers, though walking the poolside and putting feet in the shallows is fine, and the naked hot springs have no such restriction. | Web-checked | checked Aug ’26 | hawaiians.co.jp |
| Stroller friendly | Yes | Drive right up to the Water Park entrance, drop the stroller and whoever is in it, then park. Strollers, wheelchairs and prosthetics are kept at the Water Park front desk free of charge. The buildings are being made more accessible but still have steps and stairs in places, so check the barrier-free map for the route — it is one of the Japanese-language leaflets you can download. | Web-checked | checked Aug ’26 | hawaiians.co.jp |
| Outside food allowed | No | Bringing food or drink in is refused, and the list is specific: cool boxes, packed lunches, snacks, alcohol and juice. Tents and folding tables are not allowed either, and eating in the corridors is not permitted. Payment inside can be cash, e-money, QR code or credit card at the park front, the permanent shops and the restaurants. | Web-checked | checked Aug ’26 | hawaiians.co.jp |
| Kids' toilet seat & step stool | Yes | For hotel guests only, and by request: a child toilet seat and a step stool are among the infant items lent out, along with a bed guard, a bottle-warming pot, a bed pad and a diaper bucket. Ask when you book — there is a limited number of each. Staff will also sterilize bottles at the hotel front desk. | Web-checked | checked Aug ’26 | hawaiians.co.jp |
| Stroller access notesExtra info — guide only | Yes | By train it is JR Joban line to Yumoto, then a free shuttle bus or a taxi, about 15 minutes either way; a taxi from Yumoto is about ¥2,000. This shuttle is a different service from the guests-only free bus, which is listed separately. By car it is about 5 minutes from the Iwaki Yumoto interchange on the Joban expressway. Two official statements about day parking sit side by side: the fee table gives a standard car two hours free and ¥1,000 after that until midnight, while the FAQ says parking is free with a discount procedure done at one of the front desks. If you arrive with a stroller or a wheelchair, drive to the Water Park entrance, drop them there and then park. Timetables and accessible-space locations are on pages this entry could not read. | Web-checked | checked Aug ’26 | hawaiians.co.jp |
