Kisho-mon during the Middle Ages -Investigation of the written pledges from the standpoint of diplomatics

在日本中世纪时期，有一种被称为“Kisho-Mon”的许诺文件。其中包括誓言的细节和“如果我撒谎，我将受到上帝和佛陀的惩罚”。在这次调查之前，据说最古老的文件是保存在奈良东大寺的一份文件，该文件制作于1148年。然而，我建立了一个新的理论，即Kanjo-gata Kisho-mon是在中世纪之前开始制造的。这份文件包括请神请佛的术语，誓言的细节，以及关于惩罚的相同术语。2007年，在位于琵琶湖北岸的小组港遗迹中发现了一本写于1137年的木函。我们得出结论，这是一个汉字-gata Kisho-mon。这项调查更正了Kisho-mon与新来源的开始。

During Japanese Middle Ages, there were documents to make pledges called "Kisho-mon". They include details of pledges and the term "If I made a lie, I would be punished by Gods and Buddha". Before this investigation, it was said that the oldest document is the one kept in Todaiji-temple, Nara and the document was made in 1148. However, I set up a new theory that Kanjo-gata Kisho-mon was started to be made before the Middle Ages. The document includes the term to invite Gods and Buddha, details of the pledge, and the same term about the punishment.In 2007, a Mokkan written as it was made in 1137 was found in the remains of Shiozu port located on north shore of Biwako lake. We concluded it is a Kanjo-gata Kisho-mon. This investigation corrected the start of Kisho-mon with the new source.
