The University club instructor, Tom Martin Sensei was a direct disciple of Sadashige Kato Shihan when he was the Chief Instructor of the JKA in the UK. It was here that his Karate was completely overhauled. Improved teaching structure and a deeper understanding of the technical aspects of Karate reignited his passion for the art and is key to his current Karate. In 2000, he served as the University club captain (Bucho) which he held until his graduation in 2002 and competed in several competitions and tournaments during his time there.  It was also with this club that he gained his Shodan (1st Dan) in 2000 and Nidan (2nd Dan) in 2002.

In 2007 he started a new job and once again an opportunity for some lifestyle changes and found a Dojo to train in Cambridge. This Dojo was run by Ashley Martin Sensei who ran his own association, Just Karate. Then in 2015, Sensei Masaya found the English Shotokan Karate Association (ESKA) Dojo in Cambridge under Jeff Rand Sensei where he continues to train to this day. He gained his Sandan (3rd Dan) in 2016 and ESKA’s prestigious Edward Docwra Spirit Cup in 2017.
