Kōshinzuka Kofun is a zenpō-kōen-fun—a keyhole-shaped burial mound characteristic of early Japanese funerary architecture—located in Iizuna, Nagano Prefecture. This kofun exemplifies the distinctive form that combines a circular rear section with a rectangular front platform, a design prevalent during Japan's Kofun period. Designated as a Municipal Historic Site, the mound preserves evidence of the region's ancient burial practices and social structures.
