My favorite is Gangouji temple. The Gangouji temple is a small, simple, archaic temple. This temple was a place of commoners' prayers from the Middle Ages. It is different from the big temples protected by emperors, aristocrats, and Samurai.

The Gangouji temple is located in an old urban area outside the park. Therefore, few tourists come there. You will be able to see the temple calmly.

(To Mr. Jaxon Nobori's comment. )

A present Daibutsu building was rebuilt in 1709. It is already historical monuments of the Edo shogunate age. There is no reason to destroy it and to rebuild it again.
