Okunoshima

Recommended stay: 1 day
Getting around: Okunoshima is reached by a short ferry (about 12-15 minutes) from Tadanoumi Port, itself accessible by train from Hiroshima or Fukuyama with a transfer. The island is small enough to walk entirely, with a loop trail covering the main sights (the poison gas museum ruins and the areas where rabbits congregate) in a couple of hours.
Hours: Ferries run on a set schedule with roughly hourly or bi-hourly departures depending on season, so check the timetable in advance since it's the main constraint on how long you can stay on the island; the Poison Gas Museum keeps standard daytime hours, roughly 9am-4pm.

Okunoshima is a small island widely known as 'Rabbit Island' for its large population of wild but very tame rabbits that approach visitors freely for food, making it a popular, unusual day trip destination, particularly for those specifically seeking out the rabbits as a novelty stop. Feed sold on the island or brought from the mainland is the standard way to interact with them, though visitors should avoid picking rabbits up, since they can be easily stressed or injured.

The island has a much darker history than its current reputation suggests: it was the site of a secret Imperial Japanese Army poison gas production facility during the 1930s and '40s, kept off maps at the time, and the ruins of the old factory buildings remain scattered around the island alongside a small museum documenting this history, giving Okunoshima an unusual juxtaposition of a cheerful rabbit-photo destination layered directly on top of a somber wartime industrial site.

A few hours is enough to walk the loop trail, feed the rabbits, and visit the Poison Gas Museum, though check ferry schedules since departures are limited.
