The beautiful scenery of the Inland Sea of Seto has been seen in many video and print media. After a long time of longing, I finally arranged a trip across the Inland Sea of Seto between Hiroshima and Matsuyama of Shikoku on a trip to Western Japan. With the ships leaving the harbor and leaving Wugang, they enter the true blue main waterway. Except for the blue sky and the white clouds, they are the solemn sea water. Occasionally, they see the islands floating in the distance. During the course of the voyage without seeing the land, I stared at the sea for a long time, even occasionally with some illusion, as if the ferry was not sailing, but floating in a still blue pond. At this time, it seems that time has stopped.
