As for evidences, there remain the record of the 21st Kumano Betto (Chief of the shrines of Kumano) Tanzo who had his residence at Ojo-in Temple in Mt. Koya and "Kii Zoku Fudoki" (the Local History of Kii Province, Continued) that recorded a checkpoint had been built in 1332 at Yagio-guchi (Hongu-cho, Tanabe City) which is still the point for descending from Kohechi today.
このことを裏付ける傍証として第21代熊野別当であった湛増が高野山往生院に住房を構えていた史実や、現在も小辺路からの下山口である八木尾口（田辺市本宮町）に正慶元年（1332年）に関所が設けられたことを伝える史料の記述（『紀伊続風土記』）がある。
