Mikura Island, which is actually part of Tokyo is home to some 300 hundred wild dolphins which you can enjoy and swim with. There is little else to do on this island with dolphin swimming and hiking being the only main attractions. The island also does not have a beach, so there is really no sun bathing to do either. But if you love swimming with dolphins, you’re in luck.
