Overview
Den House Oshima is a whole-house rental in the Motomachi area of Izu Oshima, created by renovating a family home where the grandparents once lived. With just one room in total, a 62 sq m Japanese-Western room with a bath and toilet, one group has the place to themselves, with a capacity of 5 guests. Children who have not yet started elementary school are not counted toward that capacity, so a family of up to 8 can stay when combined with 5 adults. The house has a kitchen and a washing machine, and an onsen, the beach and supermarkets are all an easy walk away.
Rooms
This is a whole-house rental limited to one group, with just one room in total, created by renovating a family home where the grandparents once lived. The Japanese-Western room is 62 sq m with a bath and toilet, and the capacity is 5 guests. Children under school age are not counted toward that capacity of 5: up to 8 guests can stay in total, made up of 5 adults (including children of elementary school age and above) plus 3 children under school age. Note, however, that bedding, amenities and towels are provided for 5 guests only and do not cover children under school age. The accommodation plans include a children's rate. The house has a kitchen, an assortment of tableware, a refrigerator, a microwave, a kettle and a washing machine, and air conditioning is installed in each room.
Dining
This is a self-catering house with a kitchen, and only basic seasonings are provided, so guests need to bring their own ingredients and seasonings. Outdoors, you can also enjoy a barbecue on a square shichirin charcoal grill; there is a charge of 2,000 yen per day, and barbecues and other activities must finish by 9 p.m. Only handheld fireworks may be used. The restaurant at the sister property Masio is also an option, but it depends on its reservation status, so please inquire in advance; children under school age cannot use it.
Family-friendly features
Because children under school age are not counted toward the guest capacity, a family of up to 8 can stay: 5 adults plus up to 3 children under school age. Bedding, amenities and towels are provided for 5 guests only, however, so no additional bedding or supplies for young children are provided. Nature-experience programs are also available, where guests can observe and experience the nature and culture of Izu Oshima. Since children under school age cannot use the restaurant at the sister property Masio, meals will mainly be self-catered in the house's kitchen. The house stands in a residential neighborhood, so guests are asked to be considerate of the neighbors and use it within reason.
Access
The house is 5 minutes by car from Motomachi Port. A regular shuttle is not provided, but a paid shuttle can be arranged for 1,500 yen one way if requested by the day before. Seats are limited on both flights and ferries, so booking tickets early is essential. Parking is available for 3 cars, free of charge and with no reservation required. There are 2 supermarkets within about a 5-minute walk, which makes shopping easy.
