Koma Shrine is dedicated to Koma no Kokishi Jakko, a member of the Goguryeo royal family who had led the development of Koma County some 1,300 years ago. The 60th-generation descendant of Jakko currently serves as its chief priest, and the shrine is said to have the power to bless worshippers with the prosperity of descendants. The shrine is also known as Shusse Myojin because six politicians who had visited the shrine became prime ministers.
Within the shrine’s precincts are totem poles known as Jangseung, a Korean custom for warding off evil spirits, allowing visitors to the shrine to experience the connection between Japan and Korea.
Behind the shrine is a thatched-roof house known as the Koma Family Residence, a nationally designated Important Cultural Property and a popular sightseeing spot that attracts as many as 700,000 visitors annually.
