Mikurajima御蔵島
Go for 2–3 nights if you want to swim with wild dolphins in clear water; skip if you need temples, nightlife or easy logistics.
Mikurajima is a small, forested Izu island with one main draw: swimming with a resident pod of wild dolphins. There are no temples, no nightlife, no sandy beaches. The ferry from Tokyo runs overnight, so a stay of at least two nights is the practical minimum. The island is administered as Mikurajima Village and has a small permanent population of about 300.
