Tomogashima Island – It’s Like Real “Castle in the Sky”

It is said that the ruins on the island of Tomogashima in Setonaikai looks just like Hayao MIzyazaki's Castle in the Sky. This is a must see location for Studio Ghibli fans visiting Japan.

What’s Tomogashima Island Like?

Tomogashima Island - "Castle in the Sky"

Tomogashima is a group of small uninhibited islands consisting of Okinoshima, Torashima, Jinoshima, and Kamishima in Setonaikai. Among these beautiful green islands, Okinoshima is famous for ruins of fortresses built by the Japanese Imperial Army in the 1890s.  (When talking about Tomogashima, it usually addresses to Okinoshima)


The red brick ruins were slowly swallowed by the forest and are said to be similar to the scenes from Hayao Miyazaki’s movie, Castle in the Sky. They attract many visitors to the deserted island of Tomogashima. When you step into the abandoned ruins of Tomogashima, it almost feel like you are in a live action set for Castle in the sky.

There are 5 fortresses in Okinoshima. You can still go inside of some of these building, but some of them are not in good condition. Here are some of places to visit in Tomogashima/okinoshima.


Daisan Hodai Ato

Daisan hodai ato (Third battery site) is the largest fortress and probably the best maintained one as well. The ammunition chambers of the Daisan hodai ato is definitely the best known place in Tomogashima.

Inside of the chambers is like a maze. It’s dark even during the day, so it’s safe to bring a flash light with you.

Daini hodai ato (Second battery site) is a fortress facing Setonaikai. This place was bombed by the allies after World War 2, and left as it was.

Unfortunately, you are not allowed to go inside due to its condition. It wouldn’t seem weird if the robot soldier from the Castle in the Sky would appear all of sudden.


Tomogashima Lighthouse
