A mathematical tablet called sangaku was dedicated to the Ojiya Nikk􀇀 Jinjya􀊊the Shinto shrine in 1833. Although the sangaku was lost, fortunately it was recorded in a book “Sanp􀇀kaish􀇌”. The sangaku is a historical work that shows the wasan􀊊the 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.
