Koa-mi Shrine, Nihonbashi - Dragon Charm - Red Worshippers visit from all over Japan. Hand analyst Shuhei Shimada introduced it as a power spot. This is a dragon charm from Koa-mi Shrine in Ningyocho, Tokyo, famous for its good fortune in money. The shrine does not provide paper bags. Purchased January 2026. Unopened. Founded in 1666 (Bunsei 1), Koa-mi Shrine is revered as the "God of Strong Luck and Evil Warding" because the buildings within the shrine grounds were spared from the air raids during the Great Tokyo Air Raid, and all the soldiers who went to war with the shrine's amulets during World War II returned safely.
