Called the Hoando, this temple building is located at the Head Temple Taisekiji where the Dai-Gohonzon of the True High Sanctuary is enshrined. It is also where the Gokaihi Ceremony is conducted. The Gokaihi Ceremony is the audience with the Dai-Gohonzon.
During the April Tozan, Myosenji Temple members attended the Gokaihi Ceremony and depart the Hoando with other Nichiren Shoshu members from around the world.
