About the author

Reishu Sakuma carries on the prayers of his teacher, Wake Ikyō, a descendant of Wake no Kiyomaro, and performs ancestral rites (soreisai) and Shinto rites for land and buildings. Based in Hiroshima, he also serves in rites of prayer for calming earthquakes and for world peace.

At the source of these prayers lies a single aspiration handed down to his teacher. As a descendant of Wake no Kiyomaro, Wake Ikyō was taught by his mother to live for the sake of the world and of others. Upon that teaching, he opened his own path of prayer, and Reishu Sakuma learned it at his side, inheriting both the prayers and the aspiration behind them.

For land and buildings, he conducts ground-breaking ceremonies (jichinsai), framework-raising ceremonies, completion ceremonies, purifications of land and buildings, and opening ceremonies. A soreisai is a rite in which the family enshrines the spirits of their ancestors and offers them gratitude and prayers. Together with Wake Ikyō, he has held prayer rites for calming earthquakes at Lake Biwa in 2023, Lake Suwa in 2024 and Makuhari in 2025, with a rite planned at Kujūkuri in November 2026.

As a surname researcher, he traces the history of land and family recorded in Japanese surnames and compiles it into surname research reports. Grounded in Wakeryu Kaimei-gaku, the system founded by Wake Ikyō, he appraises names for newborns and name changes, as well as company names, trade names and product names, and trains name appraisers. He is also beginning to compile family trees traced through Japan’s family registers, and hopes one day to gather that knowledge into a book.

At Reishū-juku, he teaches over the course of a year how to root prayer in daily life. Through Inori no Miya on LINE, he livestreams Haishin, a prayer to the kami, at 7:00 a.m. JST on the 1st and 15th of each month, open to anyone free of charge.
