Seen from the mountain, islands of Seto Inland Sea are beautiful so much. Mt.Shiude is a popular spot to view Setouchi, called 'beauty of the sea with many small islands'. The observatory on the mountain top is famous, but this observatory beside the parking lot is a photogenic special seat.

I know, you want to go to the main observatory on the top first, but one beside the parking is also nice. Don’t miss it.
