Hakusan Shrine - Hydrangea garden
Hakusan Shrine’s hydrangea festival unfortunately was closed this year due to the state of emergency, however the flowers were still there and blooming beautifully.
The shrine is a short 2 minute walk from Hakusan Station.
There is no entrance fee. The adress of the shrine is: 5 Chome-31-26 Hakusan, Bunkyo City, Tokyo 112-0001
While you are in the area, it is also worthwhile to visit the Koishikawa Botanic Garden. This botanic garden is full of great places for picnics, and there are many sakura trees and a greenhouse there. There is a 500yen entrance fee.
