"Mashio" is the Izu Oshima dialect word for the Kuroshio Current, which brings the island its mild climate and abundant seafood. True to the name, families are greeted by the green of the natural forest spread out below and a panorama of the Kuroshio running to the horizon. Set on high ground and wrapped in birdsong, it is ideal for getting away from the bustle of the city and taking things slowly.
A particular plus for families is the private-hire open-air bath, which you can have entirely to yourselves while looking out over the greenery. Because the family can soak at their own pace, even parents with young children can enjoy the onsen feeling in a pleasant breeze without worrying about other guests.

The hotel sits on high ground in the Motomachi district, about 7 minutes by car from Motomachi Port, where ferries and jetfoils arrive and depart. It is also an easy base for spots families enjoy, such as hiking on Mount Mihara, Tsubaki Hana Garden where you can meet squirrels, and Oshima Park Zoo, which is free to enter.
This is not a hotel built around playground equipment or a pool for children; it is a resort for unhurried days spent with spectacular views, the private-hire open-air bath and island cooking. Please confirm room types, baby items available to borrow and shuttle service directly with the hotel when you book.
