Leaving from the door, what I saw was a very large arch.
We arrived at the observatory around five in the evening and waited for the changing shades. It was really unusual day and it was the first time to see the pink shade of the view.
The color came from the beautiful sunset. Two staff of the observatory standing behind me exclaimed in wonderment that they saw such sunset for the first time. The guests I guided on the day and I were really lucky to share such amazing sights.
The manhole cover above has a design consisting of Heishi Rock（瓶子岩）, a Battle ship Kaiyo-maru and a sea gull. All can be seen near Kamome(sea gull) island.
This one below is an old cover with its former town name, Kamiiso. The design consists of a salmon and a lighthouse.
The next cover says Kamiiso Yakko, which seems a scene of its festival.
Present manhole cover is as follows, with a design containing a Shinkansen bullet train and Trappist monastery.
