Hoki-ryu - 伯耆流 or Katayama Hoki-ryu -片山伯耆流 - a classical martial art of Japan. The school has more than seventy sword techniques. Many of them have been lost by most modern branches that practice Hoki-ryu. Currently, 15 main forms are the basis of almost all branches of Hoki-ryu (some groups retained the different kata). These 15 main forms are divided into two levels: Omote (6 techniques) and Chudan (9 techniques). Most of them are practiced from seiza position.
