1. Ōkunozima (大久野島) – an island full of rabbits [Hiroshima]
A 12-minute ride on a ferry from Tadanoumi Port in Takehara City, Hiroshima, will take you to this so-called ‘Rabbit Island’ of just 4.3km in width yet inhabited by more than 700 rabbits. It’s best to take some vegetables like cabbage leaves and carrots with you to please the native inhabitants. On the contrary to such cute aspects, Okunoshima is also called the island of chemical toxic gas as there were factories producing chemicals during the war. You can visit the former production sites to evidence scars from the wartime.

Located in the western part of Niigata, Sado Island is a fairly large island with approximately 262.7km in width. There are a few places of interest such as Mount Kinpoku and Toki no Mori Park, but the highlight has got to be a ride on a traditional tub-boat（たらい舟). The boatwoman will demonstrate her rowing skills but you can also try rowing the boat on your own. It’s not a skill you can acquire in a day, but you will have fun for sure.
