Nanka Judo

2020 marked the 90th Anniversary of the Nanka Judo Yudanshakai, the SoCal Judo Black Belt Consortium. When I was growing up doing judo in Pittsburgh during the late 60's I was always impressed with Nanka and Black Belt Magazine which came from the mecca of US Judo; Los Angeles.

Judo in Los Angeles was established at the Yamato building around 1917. The dojo was known as Rafu Judo Dojo with Tokugoro Ito, as the Head Sensei. By 1929 there were eight dojos and a meeting was held with their Head Sensei in which it was decided to unite and try to establish yudanshakai.


During that year, ten of the Head Sensei from Los Angles jointly wrote letters to the Kodokan, and subsequently received approval to visit Kano Shihan. The ten Sensei were Tasuke Hagio, Raitaro Hagio, Yamauchi, Yasutaro Matsuur, Yamasa, Murakami (San Fernando dojo), Iida, Matsutaro Nita, Kiro Nagano and Riyuji Tatsamo. These Sensei traveled to Japan in 1930 and actually met with Kano who gave his approval for them to establish a local Yudanshakai as branch of Kodokan in Los Angeles.

The name Nanka Judo Yudanshakai was adopted with understanding that all the Yudansha black belt members must agree to:

  • Cooperate with friendship between ALL dojos.
  • Enhance the art and teaching of judo.
  • Spread the teaching of anyone who wanted to learn the sport of judo.
Jigoro Kano Nanka

After Nanka was established many new dojos began to open, especially at Japanese Community Centers. Yasutaro Matsuura of Seinen Dojo then a 4th degree black belt was Nanka's first President. Growth accelerated following Kano's visit to several Los Angeles dojos as a delegate to the 1932 Olympics.

At the outbreak of World War II in Dec. 1941, there were twenty-six dojos in southern California, with 422 black belts and about 2,000 students. The black belts were distributed in the following manner: 6th dan-2; 5th dan-5; 4th dan-6; 3rd dan-42; 2nd dan-101; 1st dan-264; and 2 honorary black belts.

Judo continued to flourish in relocation camps such as Manzanar, Heart Mountain, Post Gila River, and Rule Lake although all other judo clubs ceased operations during the war years.

Nanka became part of the Judo Black Belt Federation of the United States in 1952 which later changed its name to the United States Judo Federation (USJF). It is one of the largest and most influential yudanshakais within that national organization.

I'm proud to have served as the past President of Nanka from 2017 to 2019. Today, Nanka has over 40 active Dojos with more than 1,000 members. In addition, Nanka hosts 4 regional tournaments each year.

When The Fast and the Furious (2001) sped into the psyche's of illegal street racing enthusiasts, with a penchant for danger and the psychotic insanity of arrant automotive adventure, the brusque bearish, quasi-hero rebel, Dominic "Dom" Toretto was caustic yet salvationally portrayed with the power of a train using a Vin Diesel engine.

A blog series analyzing the parallels between Jiu-Jitsu and Mental Health

You don't have to look very hard to find the "surface level" benefits Jiu-Jitsu can have on your mental health. It can improve your fitness, increase your confidence, help you build a friendship group, test your brain, release endorphins and serotonin, and probably lots of other things that are really hard to spell. But while these are all irrefutable facts, it's nothing we haven't heard a million times before about almost every form of exercise.

Emergency Action Plans (EAPs) help speed up your response to emergency situations, reduce injury severity, mitigate damages associated with a catastrophic event, and save lives. An EAP is not an emergency evacuation plan. For assistance in developing an emergency evacuation plan, consult your local fire and police departments for help.

When you create your EAP, assign specific responsibilities to staff members and cross-train key personnel. You can use injuries and emergencies experienced in the martial arts industry to create various scenarios, and practice responding to them. Make sure staff know where emergency equipment is located and how to use it. Post emergency contact numbers prominently by telephones for easy reference.
