• The museum was founded mainly by descendants of Hidden Christians. A private house owned by one of the descendants of the Hidden Christians who had been persecuted on Hisakajima Island was renovated to create the museum.
• The museum introduces the island’s history of severe oppression and materials describing how Hidden Christians held firm to their religious faith. About 100 items are usually exhibited out of about 200 items kept for a long time by followers on the island, including a Maria Kannon (a Buddhist statue of Kannon in the likeness of the Virgin Mary), wooden crosses and other tools for prayer, a shell horn used to signal the start of Mass, and ornaments and holy icons from closed churches.

• The museum is open from 9:00 a.m. to 4:00 p.m. (It is closed during the year-end and New Year holidays.) Admission is free of charge.
