Where: Japan (39.8° N, 140.4° E: paleocoordinates 40.3° N, 139.8° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: NN16 nannofossil zone, Tentokuji Formation, Piacenzian (3.6 - 2.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Akita Fm, which overlie the Funakawa Fm, and is overlain by the Sasaoka Fm.
