About the Setouchi Region

Setouchi, the coastal area surrounding the Seto Inland Sea, offers a unique blend of serene islands, vibrant local culture, and historical landmarks. From the spiritual calm of Itsukushima Shrine to the modern peace message of Hiroshima, this region is a journey through Japan’s past and present.

About Me

I live near the Shimanami Kaido, a beautiful route connecting Japan’s islands across the Seto Inland Sea. I often visit the area by bicycle or car to enjoy its scenery and local culture. Through this site, I’d like to share the latest information and hidden gems around the Shimanami Kaido, so that visitors from around the world can have a truly satisfying and memorable experience.
