Shironoi Ryokan and Shironoi Onsen
城乃井旅館
Does Shironoi Ryokan and Shironoi Onsen allow tattoos? In a private bath
Shironoi pumps its own two springs into a pair of storehouse-style private baths under beams salvaged from an old farmhouse, and staying guests use them free whenever one is empty.
Shironoi publishes no tattoo rule. Staying guests get two private baths, Kaede and Momiji, free and without booking: if one is empty, go in and lock the door. Day visitors can rent the same baths, or the small family bath in the inn's public bathhouse next door, by the hour.
The bath
The two private baths, Kaede and Momiji, are what make Shironoi work for a tattooed guest. They are built like old storehouses, with heavy beams taken from a farmhouse overhead, and each has a cut-stone tub big enough for four adults. Windows open onto trees and a moss garden. Staying guests use them free from 6 a.m. to 11 p.m.: no booking, just lock the door from inside if one is free, and keep it to 50 minutes. Changing rooms have their own air conditioning, a hair dryer and soaps. The water runs in fresh all the time and is changed each night. In winter the cold stone cools the water early in the morning, so the inn suggests waiting until after 6:30 a.m. Day visitors pay ¥1,500 for 60 minutes.
The inn pumps about 150 liters a minute from two springs of its own. It is Kikuchi Onsen's alkaline simple spring, clear, pH 9.5 and gentle on the skin.
Next door is the inn's public bathhouse, Shironoi Onsen, open since 1977 and free for staying guests. It has three tubs, tile murals of Mount Aso in the men's bath and local children's animals in the women's, and a small family bath at ¥1,000 for 60 minutes. The large bath costs ¥350 and is open 6 a.m. to 11 p.m.
The hotel
A small inn of nine rooms, founded in 1957, on the cherry-tree approach to Kikuchi Shrine. Four rooms are Western, with two semi-double beds and a veranda or window seat; the others are Japanese rooms with futons for one to four. No room has its own bath or toilet. Dinner is a home-style kaiseki (a multi-course Japanese meal) of about ten dishes, cooked by hand each day: Kumamoto red beef grilled on a ceramic plate, horse sashimi on some plans, and Kikuchi rice grown by the senior okami's family, cooked in well water. The inn says it keeps things simple and old-fashioned.
