Ichinomiya is the most important shrine of the silk-producing region—the god of machine weaving.
Ichinomiya is Joshu's most important shrine. The shrine precinct is distinctive in that after climbing to the top of the hill on the pilgrimage path, pilgrims must make a slight descent by stone stairway to reach the shrine situated below. The god of machine weaving is said to be enshrined here, and thus in 1866 more than 1,500 donors, including sericulture farmers and raw silk merchants, erected a pair of karagane bronze lanterns in front of the main entrance. The lanterns stand 3.95 meters tall and are an important cultural property of Tomioka City.
