GuestHouse SEN

Eight kilometres from Oshima's ferry terminal in the quiet hamlet of Izutsu, GuestHouse SEN occupies a traditional home with tatami flooring, a full kitchen, and a private sauna — rare for an island guesthouse of this scale.

The property suits families or small groups: a dining table, sofa, stovetop, microwave, and washing machine make longer stays practical. A balcony and terrace both face the mountain interior of Izu Oshima, the volcanic island 120km south of Tokyo Bay.

With only fifteen reviews averaging 9.9, SEN is not yet on the main travel circuit — an advantage for guests wanting Oshima without the day-tripper crowds that gather near the Mihara crater trail on weekends.
