Sensei Nandana Wijewardana is the founder and the Chief Instructor of Kenseikan Canada. He has over 40 + years of experience in teaching Karate. He has won the NATIONAL (ACKA) KARATE CHAMPIONSHIP in 1979 (Junior) and 1981 (Senior A). He represented Sri Lanka's National Kenseikan Karate Team. He was also awarded his 3rd Degree Black Belt (Sandan) in 1987. He also won a Scholarship (Air Lanka Ltd.) for advanced Karate training at The University of Tokyo in Japan. Later on the 16th of June 2007, Sensei received his Black Belt 4th Dan from Shihan Dai Kiyochika Oka, the Chief Instructor International at the Head Office in Tokyo, Japan. Sensei is a student of Shihan Dai Vincent Fernando (6th Dan)

Sensei Nandana traces his lineage back to the founder of modern karate himself; the Grand Master Gichin Funakoshi. Funakoshi’s student, Sensei Minoru Miyata, became one of a select few in the history of karate to receive a 9th degree black belt, and he in turn instructed Shihan Okawa who was a Senpai.  Sensei Nandana is a student of Shihan Wataru Okawa, Japan.    
​
He began his career in Canada as the Chief Karate Instructor for the City of North York Schools. He also taught at Northern Karate schools at the same time. He later launched Kenseikan Dojo in Canada on September 7, 1994. On September 15, 1996, he formally registered the Kenseikan Canada branch in commemoration of Shihan Okawa's first death anniversary.

Sensei founded the Japan Karate-Do Kenseikan Canada branch mostly as a monument to his teachers, Shihan Okawa and Shihan Dai Vincent Fernando, who passed away. He was adamant about pursuing the goals of Kenseikan Karate-Do in Canada. He was unwilling to let Kenseikan teachings perish.
​
In addition to teaching traditional Karate-Do, Sensei's philosophy is to instill greater human values and attributes in his students. He also aims to help them succeed in life by guiding them via the spiritual aspects of martial arts.
