The course starts from Kiyosu Bridge, changes the course to the Kanda River at Ryogoku Bridge, and goes around Yanagibashi and Asakusabashi. On the map, the southern shore of the Kanda River near Asakusabashi Station was intricate with Chiyoda-ku, making it difficult to determine the boundary. Proceed almost through the boundary. Crossing Yasukuni Dori, the wholesale district of Bakurocho and Kanda has a relatively easy-to-understand boundary. But it doesn't seem to be on the road. As much as possible, I went along the road at the end of Chuo-ku or near the other ward (at this time Chiyoda-ku).
Go around Kodemmacho and near Jisshi Park, cross several more streets, and follow up to Kanda Station. And this border continues to the inside of the JR Yamanote Line. Isn't there a few people who know that Chuo-ku is inside the Yamanote Line?
What I met here was the trace of Ryukanbashi. It is located at Joban 4-chome, Chuo-ku.
This used to be the Ryuka River, which separates Kanda and Nihonbashi, and it was the place where a bridge was built there. And even if the river is buried and the bridge is removed, part of the bridge is left. It seems that it is significant as a pioneer in Japan's reinforced concrete truss bridge. There's a plate to explain properly.
At the back right of the photo, there is a JR guard on the road heading toward Shin Jobanbashi. The Chuo-ku side is shown in this photo. The right and back are Chiyoda-ku. I come from the left back, go forward, pass in front of the Bank, and go to Tokyo Station Yaesu Exit, and further toward Ginza. However, the future will be another opportunity (the future is still long).
