5. Hokki-ji Temple 法起寺 or Temple of the Arising Dharma was once known as Okamoto-dera. Founded by Prince Shotoku came to understand the Lotus Sutra here in a palace that was later turned into a temple. The small three-storied pagoda is the oldest in Japan. Though most of the other buildings at Hokkiji were destroyed by fire, this pagoda indicates what the rest of the temple would have originally looked like. The pagoda is similar to the one at nearby Horyu-ji built by the same prince.
