A mathematical tablet called sangaku is conserved at the Aoshi Jinjya-the Shinto shrine in Nagaoka. Itis a historical work which shows the wasan-the traditional Japanese mathematics in Edo Period of Japan.We, however, can not read clealy the sangaku due to the deterioration by aging. Then, we have tried to restore the sangaku through the drawing by computer. Also, from the literature, we have inferred the early solution in Edo period.
