Izu Kokubun-ji

Izu Kokubun-ji is a provincial Buddhist temple in Mishima with several buildings that display traditional Japanese religious architecture from ancient times. The site preserves foundation stones and ruins that reveal how the complex was originally laid out and constructed.

The temple was founded in 741 by Emperor Shomu during the Nara period as a significant religious center for the region. Over the centuries it underwent multiple reconstructions due to wars and earthquakes, which shaped its development through different historical eras.

The temple shifted through different Buddhist sects, starting as a provincial temple, then converting to Shingon sect, and finally becoming part of the Nichiren tradition.

The site is located about one kilometer south of Mishima Station on the JR East line and is accessible by walking or local transport. The Mishima City Museum displays archaeological artifacts from the temple, including ancient roof tiles decorated with lotus patterns.

Archaeological excavations revealed that the original complex included a seven-story pagoda standing about 60 meters high, supported by large foundation stones. This impressive structure was a major landmark of the province in ancient times and its remains show how advanced Japanese builders were.
