Senami Hamanasuso

Does Senami Hamanasuso allow tattoos? In a private bath
Hamanasuso is a four-story lodge facing the Sea of Japan, and six of its rooms have a round glazed tub on the balcony that it fills from the Senami source.
Hamanasuso publishes no tattoo rule for its shared baths. The way to bathe alone is to book one of its eight rooms with a tub of their own: six with an open-air bath on the balcony and two Japanese-modern special rooms with an indoor bath, all filled, the lodge says, with water from the source.
The bath
Eight rooms have a tub of their own, and the lodge says all of them use the source water. Six have an open-air bath on the balcony; the photos show a round, glazed red-brown tub with a ceramic spout, set on wooden decking behind a slatted screen. The lodge says you can bathe whenever you like, for as long as you like, with no one else around. Two Japanese-modern special rooms have an indoor bath instead. Guests in these rooms can use the shared baths as well.
The lodge tells the town's story: the spring burst out in 1904 when a crew drilling for oil struck boiling water, and it still comes up above 90°C, which is why people call it netsu-no-yu. It lists the water as a sodium chloride spring for nerve, muscle and joint pain, fatigue, stiff shoulders and cold sensitivity. The 2nd-floor view bath and the open-air bath, one of each for men and women, look over the sea toward Sado and Awashima, and the lodge says the sunset colors the water. They open noon to midnight and 5 to 9:30 a.m. Day bathing is listed from noon to 4 p.m. for ¥500, but the lodge asks day visitors to call first.
The hotel
A four-story concrete lodge run by the Niigata municipal employees' mutual aid association as a recreation lodge, open to anyone. The lodge says every room looks out on the sea. Most rooms are Japanese-style, with one single and four twins. Dinner, built on local seafood and Murakami beef, is served in the dining room Senami at 6, 6:30 or 7 p.m., chosen at check-in. There is Wi-Fi throughout, a shop, a foot bath, a facial salon on Saturdays and, beside the lodge, the Senami Campfield Somaru campground.
