Koami Shrine is very famous for its blessings of "strong luck and warding off evil" and "financial fortune." It is considered a "god of strong luck" due to its miraculous survival of the Great Tokyo Air Raid and the Great Kanto Earthquake. The carvings of the ascending and descending dragons, the money-washing well, and the owl amulet are particularly popular, making it one of the leading power spots in the city center.
