研究中寺院・文庫に秘蔵され、口伝のみで封じられてきた様々な分野の古秘伝書を広く収集・翻刻し、現代語訳と注解を付して学術的に公開する。仏教・神道・武家・修験など多岐にわたる文書を対象に、その解読と分析を通じて、日本中世における秘伝の実態と継承構造を一次史料から明らかにする。比叡山延暦寺蔵（山門藏本）『佛身一躰灌頂鈔 附 一所三嶋參詣』の全文翻刻・現代語訳はその一例である。Collecting, transcribing, and bringing to scholarly publication a wide range of historical secret texts from various fields — long kept in temple and library archives and transmitted solely through oral tradition. Covering documents spanning Buddhism, Shinto, warrior culture, and mountain asceticism, the research illuminates the nature of secret transmission and its structural inheritance in medieval Japan through primary sources. The complete transcription and modern translation of Busshin Ittai Kanjōshō, fus. Issho Mishima Sankei (Enryaku-ji, Sanmon archive) is one such example.
研究中『神道集』は、国家や教団が定めた公式の格付けではなく、人々が実際に命を預けた場所の記録として読むべき文献である。死と隣り合わせの日々のなかで病から回復し、傷が癒え、命が救われることを求めて祈った人々の体験——「ここで祈ったら本当に助かった」——その積み重ねが語り継がれ、霊験の強度による序列が自ずと生まれた。南北朝時代（14世紀）成立の唱導説話集。全10巻の原典解説を連載中。 神道集を読む → The Shintōshū should be read not as an official ranking decreed by the state or institution, but as a record of the places where people truly entrusted their lives. In a world where death was never far away, people prayed with desperate need — to recover, to heal, to survive. "I prayed here, and I was truly saved." It was this accumulation of lived experience that gave rise to a natural hierarchy of sacred sites. A 14th-century compendium. Annotated source texts, ongoing. Read the Shintōshū →
