Randori Kihon no Kata Junana Hon

 
 
 
 
The Competition Techniques
 
 
This is a kata of 17 aikido techniques which have been isolated for two specific purposes.
 
One is as the name states in Japanese, the 17 actual basic foundation techniques of aikido taken out of the thousand or so techniques and combinations which Ueshiba sensei traditionally taught individually.
 
More specifically, in this form, these are the techniques which can safely be used in randori practice and competition. It is only these techniques and their recognizable versions that are allowed by the rules. Use of other techniques incur penalties or disqualification. In Judo, the Gokkyo is the 40 technique equivalent of allowable competition techniques.
 
This video version by Endo Sekio is toshu (unarmed) and is used in toshu randori and competition where opponents face each other in the manner of judo unarmed combat.  The more popular form of randori competition nowadays is performed with one partner attacking with a rubber tanto (knife) and so this same kata of 17 is performed by attacking using a rubber tanto.

Rules for Randori Competition
 
 
This publication revised in 2008 explains the rules and regulations both for the players and the referees / judges.
 
It is used for training the referees in judgement and procedures and also needs to be explained by coaches and instructors to the players so as to prepare the players for the contest. If players are not familiar with the regulations it leads to disappointment and frustration and so coaches should place great importance to the understanding of the rules.
 
Oceania Aikido Kyougi Renmei has a training system for referees and also holds seminars for players. Watch the News & Events Page for such courses.
 
The same rules are in the recently published english text by Nariyama Shihan called Aikido Randori.  You can download a copy of these rules in the next column to the right and also  there is a  link to purchase the text from the publisher if you want.  You will need to pay local postage.
 
You can purchase the booklet as shown for 2,500 yen from JAA but you need to make the trip to Japan !! Good Luck

Kata Competition, Mixed Event Team Competition and the Rules

 
Kata competition is non-combative, it is a judgement system of competition in appearance similar to Olympic Gymnastics. It judges on effectiveness of technique, demonstration of aikido principles and discipline. It is suitable for all ages and those in good but not combative physical condition. It is just as demanding as randori competition and training but avoids any chance of injury. You can download the current rules in the column to the right.
 
The Mixed Event Team competition is a team competition and each team will perform two kata demonstrations one free knife attacking competition and two randori styles competition
(5 altogether). As with randori team events, the winning team will be the one with a minimum of three event wins. It is exciting and very competitive. The rules and description are in the rules file to the right.

Overview
 
The competitions are the traditional Japanese style of "knockout" competition where the individual or team competes until they lose and then retire. The last four enter a semi final and final round where 3 will place 1st, 2nd or 3rd.
 
The "repecharge" or "pool" method as used in many other sports has not yet made its debut in aikido competition.  Though the number of competitors has increased dramatically, the pool of experienced and skillful officials has struggled to keep up with the entry numbers making it difficult to entertain a repecharge just yet.
