Chokokuji Temple

Chokokuji (長谷寺) is a Soto Zen temple located in an area between Shibuya, Roppongi, and Aoyama. It's not so far from the Nezu Museum.
Chokokuji was founded in 1598. Its complex was destroyed in WWII and present one was reconstructed after the war.
There's a wooden statue of Kannon 10 meters (33 feet) high here.
It's a 10-minute walk from Omotesando Station of the Tokyo Metro Hanzomon Line, Ginza Line, and Chiyoda Line.

Hatto is the main hall of this temple.

Sodo is the hall monks practice zazen.

Inside the Kannondo (Hall for Kannon) is a 10-m (33-ft) wooden statue of Kannon, a Buddhist divinity of mercy. You can offer prayers to her (or him, since its gender is unknown) from 6am to 5pm freely.
