The enchanting island that reminds you of the popular anime movie.

Last update :

A part of Setonaikai National Park, Tomogashima is the name for four islands in the Kitan Channel. Of those, Okinoshima looks like the world of the nationally-famous animation and is called Laputa Island. From the main Island’s Kada Port, a 20-min ferry ride will take you to the island.

In the Meiji period, much of the Island was developed as the Imperial Army’s fortress. The ruins of cannon platforms and ammunition depots still exist. Though beaten by wind and rain, many of the brick structures are standing strong. Follow the tour map and hike on the path throughout the island. Alongside the 2 and a half hour course at a leisurely pace, there are many viewpoints that overlook the panoramic blue ocean.

The temperatures are mild throughout the year, and you can see almost 400 kinds of plants, some of which are rare species.
