Steam threads across a gray morning as a small car climbs toward Sukayu Hot Spring on the Hakkoda slopes. You step from the vehicle into air that smells faintly of iron and earth; the hotel’s long, wooden facade holds the low heat of centuries of bathing culture.

Sukayu has served travelers and local mountain workers for over a century and is famed for its large communal Sennin-buro that grew from local bathing traditions tied to seasonal mountain labor.
Conservation
The onsen’s operations are sensitive to water use and local forest health; visitors are asked to conserve water, avoid soaps in natural outlets, and follow marked paths to limit erosion.

Book morning slots for quieter bathing
Early tours often include women-only hours in the Sennin-buro and fewer visitors in communal areas.
Cover or conceal larger tattoos
Tattoos larger than roughly 95×140mm are generally not allowed; small tattoos can often be covered with provided stickers.

Bathing cloth rental (~500 JPY), tattoo stickers (~200 JPY) and a private-car gas contribution (~3,000 JPY) are cash items to expect.
Shower thoroughly before entry
Rinsing and washing at the communal stations is required etiquette — it keeps the baths clean and shows cultural respect.
Quick-dry towel
A personal towel is hygienic and useful for drying between the changing area and the tub.
Bathing cloth (or rent on site)
Useful if you prefer not to bathe nude in mixed or communal areas; available to rent for a fee.
Warm layers
Temperatures can drop quickly after leaving the hot water, especially in mountain air.
