In the Taiseki-ji school of Nichiren Buddhism, it is claimed that the most profound and important teachings of Nichiren have been passed exclusively from one high priest to another, through a process of “transmission of the heritage of the Law to only one person” (yuiju ichinin kechimyaku sojo). The purpose of this paper is not to ascertain whether this claim is true or not, but to point out that the core content of this so-called secret transmission of teachings appears to have already been disclosed by the school's 26th high priest, Nichikan. In this paper, I will clarify the validity of my hypothesis by reexamining Nichikan's writings from the viewpoint of disclosure of the transmission teachings of the Taiseki-ji school.
