Asakusa holds Plants & Bonsai Market in the last weekends of May and June. It is one of the largest street market of this type in Tokyo. This market is a festival of Asakusafuji Sengen Shrine.
Sengen Shrine is about 15 minute walk from Asakusa Station. There are Sengen Shrines throughout Japan. They worship Mt. Fuji. Asakusafuji Sengen Shrine has a small Mt. Fuji inside the shrine. Mt. Fuji opens for climbing on July 1st and on that day during Edo Era of 17 – 18th century, those who could not go to Mt. Fuji gathered at the shrine.
The entrance of the market is near from the shrine.
There are many kinds of plants and flowers from the small ones to the big ones.
