The Rōhai kata are a family of kata practiced in some styles of karate. The name translates approximately to "vision of a Crane" or "vision of a heron". The kata originated from the Tomari-te school of Okinawan martial arts. It was called Matsumora Rōhai, after Kosaku Matsumora, who was presumably its inventor. Ankō Itosu later took this kata and developed three kata from it: Rōhai shodan, Rōhai nidan, and Rōhai sandan. In Shorin-ryū/ Matsubayashi-ryū this Kata introduces Gedan Shotei Ate (Lower/Downward Palm Heel Smash) and Ippon Ashi Dachi. (One Leg Stance) It contains a sequence of Tomoe Zuki (Circular Punch) exactly the same as the one in Bassai, although the ending of the sequence chains into Hangetsu Geri/Uke (Half Moon Kick/Block)
