There are quite a few temples and shrines in Yushima area. When I biked to Shinobazu-no-ike Pond to see lotus flowers and unique monuments, I biked around Yushima and visited one of the temples Rinsho-in.
Rinsho-in temple was built in 1624 by Lady Kasuga who was a wet nurse of the third Shogun, Iemitsu Tokugawa. She was well-known by her political power which influenced the politics of Edo Government and Shogun. Because the temple has her grave, many people visit here. The area near here in Bunkyo-ku has a place-name of “Kasuga” which was named after Lady Kasuga.
The cemetery is not so big but it has a solemn and serene atmosphere.
Address: 1-8 Yushima 4-chome, Bunkyo-ku, Tokyo
They offer early morning zazen or zen meditation session from Monday to Friday. For details, please see the website in English.
I will add one more temple near from here. That is Koan-ji Temple.
It is a small temple and maybe easy to miss. However the structure of the temple is actually unique because it was built in the style of a traditional Japanese warehouse. If you look at the window closely, you will notice the thick wall which protect the building from the fires. This temple was built in 1606 and moved to the current place in 1616.
Address: 12-13 Yushima 4-chome, Bunkyo-ku, Tokyo
