private individual trips. This pilgrimage in the sectarian parlance is called "Tozan" (登山, "Mountaineering, to climb the mountain") for the purpose of worshipping the Dai Gohonzon in person. The sect bases this practice in the ancient custom of early supporters of Nichiren who also visited him during his lifetime over perilous roads and mountains, now re-interpreted as a similar pilgrimage towards the Dai Gohonzon, which represents Nichiren in a mandala format. The Gokaihi ceremony In Japan, a "Gokaihi" (御開扉, English: "Sacred Opening of (Butsudan) Doors") is a ceremonial rite that exposes a particular sacred Buddhist image that is hidden and revered in a particular religion or sect. In Nichiren Shoshu ritual practices, this refers to the ceremonial audience with the Dai Gohonzon officiated by the High Priest granted to Hokkeko believers who have personally requested to participate, which is oftentimes the main purpose of a pilgrimage visit to the Head Temple. The volition of free will, confirmation of registered membership and an offertory fee is part of the protocol to enter the Hoando building to participate in the service. List of buildings The following significant buildings are listed for their historical and architectural value: Sanmon Gate The Sanmon (written 三門, sometimes 山門) gate is Taiseki-ji's "main front door" and has been designated as a Shizuoka prefectural cultural asset.

It was recently restored, and its Gohonzon was ceremoniously re-enshrined within again on 15 January 2021. Mutsubō The first was erected in 1290 as Taiseki-ji's first building. It has been rebuilt many times since, but the Gohonzon (object of veneration) it houses is attributed to temple founder Nikkō Shōnin dating from November 1332. It maintains its original design of having six rooms. The current structure, which uses much keyaki heartwood, was completed in 1988. The High Priest of Nichiren Shoshu proceeds to the Mutsubō on concluding Ushitora Gongyo in the Kyakuden (see below) to perform another gongyo recitation with young priests and acolytes.
