Fossil footprints of a bird referable to the suborder Gruidea were found from the Pliocene Kobiwako formation of Mie Prefecture, central Japan. The footprints are relatively large and show four toes. Toes II to IV direct forwards with a wide splay angles, while toe I points backwards at a low position. Each toe is wide and with a claw impression at the tip. Metatarsal impression is preserved on the sole. A small area of webbing is present between III and IV only. The stride is 320〜500mm. This record provides additional information about the fauna of the Pliocene Kobiwako formation.
