Sangaku-ji, Buddhist temple in Komono, Japan
Sangaku-ji is a Buddhist temple in Komono featuring traditional Japanese wooden architecture that holds hundreds of mathematical tablets inscribed in its halls. The boards date mainly from the 18th and 19th centuries and display complex geometric problems.
The temple became known during the Edo period as a place where scholars presented mathematical riddles as spiritual offerings. This practice made it a center where religious devotion and intellectual achievement met.
The wooden Sangaku tablets here connect mathematics with spiritual practice through geometric designs that visitors left as offerings. This blend shows how mathematical thinking became part of religious life.
Take time to examine individual boards closely, as each displays a different geometric problem with its own solution approach. Visiting during quieter periods and with good lighting helps you see the carved details more clearly.
Some of the older tablets show solution methods developed independently from Western mathematical traditions. These examples offer a rare look at Japan's own mathematical culture long before Western influence reached the country.
