Nunakuma Shrine
In the Engishiki Jinmyocho, a document from the middle of the Heian period, there is a description of a Shikinaisha called 'Numakuma-jinja Shrine' located in Numakuma District, Bingo Province. The book offers two possible readings of the name, "Nunasaki" and "Nunakuma". However, the location of this Shikinaisha remained unknown. Through historical research after the early modern period, it is currently identified as Watarimori-jinja Shrine, but it is unclear whether it is located in Tomo.
