・Over 10,000 heads of Christian rebel forces killed in the Shimabara-Amakusa Rebellion were buried in three places (Nagasaki, Arima, and Amakusa). This is the one of the three sites.
・In 1641, after the end of the Shimabara-Amakusa Rebellion, Suzuki Shigenari was sent to Amakusa Island as the magistrate to reconstruct the devastated region.
・With the cooperation of his brother Shosan, who was a Buddhist monk, Shigenari reconstructed temples and shrines and urged Christians to convert to Buddhism by disseminating the teachings of Buddhism.
・Under such circumstances, Shigenari erected a stone monument to console the spirits of the victims of the Shimabara-Amakusa Rebellion in September 1647. The memorial monument for Tomioka Christians has an epitaph chosen by Chuka Keiho, the chief priest of Rurikoji Temple in Yamaguchi.
