Okunoshima

A former poison gas island now overrun by hundreds of fearless wild rabbits.

#Water#Family#Couple#Relaxed#Unique

The rabbits arrive before you have left the pier. Hundreds of them — wild, unafraid, and deeply interested in whatever you are carrying. Ōkunoshima is a speck in the Inland Sea off Hiroshima that made poison gas for the Imperial Army from the late 1920s until 1945, a history so secret the island was scrubbed from some maps. Today no one lives here permanently except the rabbits.

The Poison Gas Museum, opened in 1988, documents the island's production of thousands of tonnes of mustard gas and tear gas, and the workers who were poisoned making it. Where the rabbits came from is argued over: the likeliest story is a release of school rabbits in the early 1970s, since the wartime laboratory animals were killed when the plant was demolished. The island is car-free, with a walking and cycling loop around the shore past power stations and storage bunkers slowly being swallowed by vegetation. A single Kyūkamura resort hotel is the only place to stay, with views across the Inland Sea.

Family

Children will talk about the rabbits for years. The island is flat, without cars, and small enough that even young legs can walk the whole loop, with the museum a sober counterweight adults can decide how to frame.

Couple

The contrast between the island's dark history and its absurd present — ruins and rabbits — creates a mood unlike anywhere else in Japan.

Why This Place
  • Hundreds of wild rabbits gather at the ferry landing, and they will follow anyone with vegetables.
  • The Poison Gas Museum documents a wartime history kept secret until the island was reopened to the public.
  • A car-free loop circles the whole island in about an hour, past ruined factories and bunkers.
  • One resort hotel overlooks the Inland Sea — the only beds on the island.
What to Eat

Setouchi fish and the region's citrus at the island hotel's dining room, the only kitchen on Ōkunoshima.

Takoyaki or a bento from Takehara's harbour before the ferry — the rabbits get carrots, you get lunch.
