We studied Problems of the Pierced Object in the Old Japanese Mathematics and we took statistics on these problems in mathematical Tablets. The investigation revealed the fact that many problems were studied during the Bunsei (1818〜1830), especially in and around Edo. And after that period they spread in the country. The main objects of this paper are to give the analysis of the above-mentioned investigation, especially to make the history of mathematical solution clear in these problems.
