In the present research project, I examined the contents of the Tale of the Heike, which is one the most famous classic literatures in Japan, especially the description in “the Fan Target” from a scientific viewpoint. A conversion of thecalendars, a simulation of the solar motion were carried out to determine the date and time of the shooting. There are two theories about the length of “a tan”, which is the units of length in the medieval period: 2.7 m and 11 m. In order to determine which is more probable, the data of shooting competitions during the Edo Period was analyzed to calculate the target-hitting probability. The effects of wind and waves were also considered.

在本研究项目中，我从科学的角度考察了日本最著名的古典文学之一《平家物语》的内容，特别是其中的“扇靶”描述。对日历进行了转换，模拟了太阳运动，以确定拍摄的日期和时间。关于“a tan”的长度有两种理论，这是中世纪时期的长度单位：2.7米和11米。为了确定哪一个更有可能，对江户时代射击比赛的数据进行了分析，以计算命中目标的概率。还考虑了风和波浪的影响。
