A Jomon rock shelter on Shikoku, Japan with pottery radiocarbon-dated to the late 11th millennium BC, similar to that at Fukui and Sempukuji. It is associated with bifacial points rather than with microblades. Incised flat pebbles representing human females were also found - the earliest portable art found in Japan. The 20 human and two dog burials in one of the upper layers are among the oldest Initial (Incipient) Jomon burials.
