Nami no Yu Akane in Obama: Booking, Sunset and Sea Conditions
Plan a private soak at Nami no Yu Akane in Obama: current rates, when to book, sunset timing, sea-condition cancellations and bus access.
Nami no Yu Akane is a single private outdoor bath beside Tachibana Bay. It is a good fit if the sea-facing setting is the reason for your visit; the water and sky are part of the experience. At high tide, the bath can sit only about 20 centimetres above the sea. That closeness also means the operator may stop bathing when wind, waves, high water or a spring tide make conditions unsafe.
The practical details matter more here than at an ordinary day-use bath. You can book only on the day before or the day of your visit, payment is cash only, and towels are not supplied. Treat a sunset soak as a plan that depends on weather and availability, not a guaranteed view.
Book around the sunset, not a fixed clock time
The bath is open from 10 a.m. to 11 p.m., with last reception at 10 p.m. A session lasts 50 minutes. Sunset shifts substantially between summer and winter, so choosing 5:30 p.m. by habit can leave you too early or too late. Check Unzen’s sunset time shortly before your trip, then ask whether a slot around dusk is available when reservations open.
Cloud, rain or mist can hide the sunset even when bathing is allowed. The more dependable reason to choose Akane is the open-air setting directly beside the bay; the sunset is a bonus. If you would be disappointed without a clear horizon, keep an indoor private bath in Obama as a backup.
The ryokan association and Nagasaki tourism profile place the bath roughly 20 cm above sea level at high tide. This describes the setting, not a safe bathing level: the operator may suspend use when tides or waves make conditions unsafe.
Current price and what the session includes
| Group size | Price for 50 minutes |
|---|---|
| 1–4 people | ¥3,000 total |
| Each person from the fifth onward | +¥500 |
The base price is per group, not per person. Four guests pay ¥750 each before add-ons; groups of five or more should allow time for everyone to change and bathe within the same session.
Bring cash. The operator does not accept credit cards. Towels are not included, though shampoo is available. There is no shared public bath: the outdoor bath itself is reserved for one group at a time. The operator does not store valuables, so carry only what you need and ask on arrival where to keep belongings.
Older pages for Obama’s walking route still show ¥2,000 for a 60-minute session. That is not the current offer; use the operator’s page for the latest rate and booking instructions.
The operator handles bookings through YUASOBI; the ryokan association’s general contact desk is not the reservation desk for either facility. Because booking opens only the day before or on the day, check availability and sea conditions together rather than relying on an old directory listing.
Getting there by bus
The closest listed stop is Nishitoyama-guchi, about a three-minute walk away. Obama bus stop is roughly nine minutes on foot. The address is 20 Obama-machi Marina, in the waterfront area near YUASOBI and the Hot Foot 105 footbath.
Plan the return journey before choosing an evening booking. Opening until 11 p.m. does not mean there will be a bus back to Isahaya or Nagasaki at a convenient hour. Check the latest Shimabara Railway or prefectural bus timetable for both directions, then leave time to change after the session. The Obama car-free day-trip guide covers the wider route.
Water information and the local 105°C figure
The operator identifies the spring as sodium chloride (a chloride spring). It does not publish a current facility-specific source temperature, pH, flow rate or fixed bathing temperature. Obama Onsen’s commonly cited 105°C is a regional source-area figure; it should not be presented as Akane’s water temperature.
Guide ratings
The guide scores Akane 85 for comfort, 50 for bath variety, 75 for upkeep, 100 for atmosphere, 95 for quiet, 90 for access and 85 for value. Those scores reflect its focused offer: a highly distinctive private view, with just one bath and more weather exposure than an indoor facility.
Who should choose Akane?
It works particularly well for couples or a small family who want a private bath without splitting into separate men’s and women’s areas. The flat rate also makes the per-person cost lower when two to four people share a session. Larger groups need to account for the extra-person fee and the short changing window.
Akane closes when sea or weather conditions make bathing unsafe. The operator gives no step-free measurements for the approach; if you have mobility needs, ask about the route from the entrance and the bathing setup before you go.

Who it suits—and who should choose indoors
Couples and small families can share the base rate, which covers up to four people; each additional guest costs ¥500. A 50-minute slot may feel rushed for a larger group once changing time is included.
Older guests, young children or anyone who needs shelter from cold and rain may prefer Yunoka’s indoor Take-no-yu or YUASOBI. The public listings do not give step-free access measurements, so ask before booking if mobility is a concern.
Tattoo policy and related reading
Akane publishes no tattoo rule, so contact the operator before travelling if that could affect your access. For an indoor private room with steam sauna and cold plunge, see the Akane–YUASOBI comparison; Yunoka’s rooms are the lower-cost private-bath alternative.
