("JSKA" redirects here. For Japanese ska, also known as J-ska, see Japanese ska.) Japan Shotokan Karate Association (JSKA) is one of the fastest growing Shotokan Karate associations in the world, founded by Keigo Abe in 1999. Abe is a former instructor graduate of the Japan Karate Association and trained and taught at the JKA Headquarters for nearly 35 years. He held a number of senior positions within the JKA and latterly the Matsuno section of the JKA. He had been a senior student of Nakayama and as such the teachings of Nakayama remain an integral part of the evolution of the Shotokan style within the JSKA.
