A mathematical tablet called sangaku was dedicated to the Ojiya Nikk Jinjyathe Shinto shrine in 1833. Although the sangaku was lost, fortunately it was recorded in a book “Sanpkaish”. The sangaku is a historical work that shows the wasanthe traditional Japanese mathematics in the Edo period. Then, we try to restore the sangaku through the drawing by computer. Also, we show the solution to the problems described in the sangaku.
