Tsunozuka Kofun is a keyhole-shaped burial mound located in the Isawa neighborhood of Ōshū, Iwate Prefecture, in Japan's Tōhoku region. Designated a Historic Site of Japan, this zenpō-kōen-fun (keyhole-form tumulus) holds particular significance as the northernmost example of its type yet discovered. Its presence in what was traditionally Emishi territory demonstrates the expansion of Kofun period culture into northern lands.
