Izu Oshima Guide
Short, practical guides to Izu Oshima for visitors from overseas. One new guide a day at most, each one built from public sources (village and city offices, the prefecture, national agencies, transport operators) that we list at the end with the date we read them. If we could not check something, we say so and leave it out.
