Opened in March 2007, the Shimane Museum of Ancient Izumo displays ancient artifacts, including the remains of Izumo Taisha's giant stairway pillars, Japan's largest collection of excavated bronze swords and bells, and Japan's only complete version of the Izumo no Kuni Fudoki (Ancient Chronicles of Izumo). The ancient culture of Shimane is introduced based on three themes ; the Izumo Grand Shrine, the Izumo fudoki, and bronze implements.
