From the store listing: “"Kofun" recorded in this app does not vaguely refer to "burial mounds of old times." It refers to a specific type of burial mound built during the Kofun period (around the middle of the 3rd century to around the 7th century), which is an archaeological period that follows the Yayoi period in Japanese history.…”
