Kumite is simply an exchange of techniques between 2 (or sometimes more) individuals. Kumite can range from simple pre-set 1-step attack and counter scenarios (ippon kumite), to complex pre-set scenarios (yakusoku randori kumite), and can also included free exchange of techniques (jiyu kumite).

In Shorinjiryu, the practice of pre-arrange yakusoku randori kumite (often just called randori) is a major component of our practice. Having the techniques known in advance allows participants to develop speed, distancing, timing, power, footwork and technique, with the comfort of knowing what attack to expect.

Most of the Randori focus on the primary techniques of karate – stances (tachi), footwork (ashi sabaki), punches (tsuki waza), kicks (keri waza), strikes (uchi waza) and receiving techniques (uke waza), although some of the more advanced drills incorporate grabs, locks, throws, chokes and the counters to those techniques.

There are also randori that utilise various weapons for one or both of the participants.

The major series of randori kumite practiced in various Shorinjiryu schools include the following:

• Renshu Kumite (Renshu Ichi, Renshu Ni)
• Randori Kumite (Randori Ichi, Randori Ni, Randori San, Randori Go)
• Naihanchin Waza
• Naihanchin Waza Ni
• Nijushiho Waza
• Sanchin Waza
• Itsutsu no Waza
• Sankakutobi Shodan Kumite (Ichi, Ni and San)
• Sankakutobi Nidan Kumite (Ichi, Ni and San)
• Sankakutobi Sandan Kumite (Ichi, Ni, San, Yon, Go)

In addition there are a variety of ippon kumite (1 step), sanbon kumite (3 step) and gohon kumite (5 step) drills that typically feature a single attack that is responded to with 1, 3 or 5 defensive techniques. Major examples of these style of kumite include:

• Ten-Chi-Jin Kumite (3 hand and 3 foot drills)
• Gokyo no Kumite (5 hand and 5 foot drills)
• Renzoku Kogeki (5 hand and 5 foot drills)
