A mathematical tablet called sangaku was dedicated to the Hakusan Jinja-the Shinto shrine in Niigata in 1803. Although the sangaku was lost, fortunately it was recorded in a book Saishi Shinzan - the collection of sangaku problems. The sangaku is a historical work that shows the wasan - the traditional Jananese mathematics in the Edo period of Japan. Then, we try to restore the sangaku through the drawing by computer. Also, from the literature, we infer the solution in the Edo period to the sangaku problem.
