Iseya
伊勢屋
Does Iseya allow tattoos? In a private bath
Iseya has stood in Obama for more than 350 years, and its main-building rooms now each carry a semi-open-air tub running on the inn's own 100°C source. Three family baths rent by the hour for anyone who wants more room.
Iseya publishes no tattoo rule. Every room in the main building has its own semi-open-air bath fed from the inn's own source, so a tattooed guest bathes in the room. There are also three family baths booked by the hour at 3,000 yen. The annex Ocean Suites have a sea-view bath that is not spring water.
The bath
Iseya draws its own source, a weakly alkaline sodium chloride spring that comes up at about 100°C, and the inn repeats the town's claim that no hot spring in Japan gives off more heat. Bathing is listed for rheumatism, nerve complaints, gout and women's ailments, and drinking the water for gastritis, anemia and constipation. The large bath is an airy room the inn says lets the Obama breeze through, with an open-air section and a rest area; day visitors use it 10 a.m. to 7 p.m., last entry 6:30, for 1,000 yen (children 500, infants free) with shampoo, soap and towels included.
The rooms are where a tattooed guest bathes. Every Standard and Junior Suite room in the main building has a semi-open-air bath of its own, fed from the inn's source and flowing through, with a handrail and steps into the tub, a Hansgrohe rain shower beside it and the sea in the window. The annex Ocean Suites have a sea-view bath on the terrace, but the inn marks it plainly as not spring water; those guests walk over to the main building's large bath.
Three family baths rent by the hour at 3,000 yen a group, booked through the inn's reservation system with reception until 6 p.m.; the inn assigns whichever is free, so the bath cannot be chosen. Children of about seven and up bathe separately under the prefecture's rule.
The hotel
The inn says it was founded in Obama more than 350 years ago, and it now runs as a modern building with Danish furniture in the lobby, a library of chosen books, a select shop and a terrace café selling lemonade, paninis and hot-spring eggs. Main-building rooms are 39 or 51 square meters with two semi-double beds and a tatami corner, sold with dinner and breakfast of local seafood, farm vegetables, Nagasaki beef and Unzen pork; the annex Ocean Suites are 56.5 square meters with a terrace and are sold room-only. Check-in 3 p.m., check-out 10 a.m.

Getting there
The inn publishes no transit directions, only its address and the municipal car park a minute away. From Isahaya Station the Shimatetsu bus toward Obama and Unzen takes about an hour, by the count of the neighboring inns; Iseya shares the 905 block with Yunoka, whose stop is Nishi-Tozanguchi, a minute's walk. From Hakata the JR Kamome reaches Isahaya in about 1 hour 40 minutes.
