The sunset from Kasado island in Setouchi national park is one of the best in west Japan.

Especially the sunset view with the "Hanaguri Rocks"(the rock with a hole made by erosion) is exceptional and visited by many photographers. The sunset in the winter is recommended for the madder red ocean.

(Now the hole of Hanaguri rocks are the eroded holes additionally spread by the army in the wartime to hide their ships)
