Christianity
Like many other areas in Nagasaki Prefecture, the now-dissolved municipality of Sotome in Nishisonogi Peninsula was an area with a number of Kakure Kirishitans, Japanese Christians who went into hiding during the Edo Period. When the prohibition against Christianity was revoked in 1873, the Kakure Kirishitans of Sotome, as well as Hirado, Shimogoto, and Ikitsuki, continued following their unique religious traditions, although these had diverged significantly from mainstream Christianity over time.
