Rōhai

Karate kata, breaking a board or brick

Rōhai (鷺牌) meaning “image of a heron” or “sign of a heron” is a family of kata practiced in some styles of karate. 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 and Matsubayashi-ryū this kata introduces Gedan Shotei Ate and Ippon Ashi Dachi. It contains a sequence of Tomoe Zuki exactly the same as the one in Bassai, although the ending of the sequence chains into Hangetsu Geri/Uke.
