Sonny Loke sensei began his aikido journey in 1972 with Pak Wai Phang sensei in Chung Ling High School, Penang. Sonny sensei started teaching aikido in Kuala Lumpur in 1991.

In May 1995, Sonny sensei attended the 1^st International Aikido Yoshinkan Instructors Gasshuku (training camp) in Tokyo, Japan. Upon his return, Sonny sensei decided to devote his life to teaching Yoshinkan Aikido full-time and established Yoshinkan Aikido Malaysia (YAM) in June 1995. YAM is affiliated with the Aikido Yoshinkai Foundation in Tokyo, Japan.

Since 1995, Sonny sensei has received instruction solely from Takeno Takafumi Kancho, for over 20 years, and is the first foreign instructor to be affiliated directly to Takeno Kancho.

Sonny sensei was awarded Tokubetsu Enbu Shou (Special Demonstration Award) by Takeno Kancho at the 27^th Aikido Yamanashi Yoshinkan Annual Demonstration in 2014.

In 2015, Tokyo, Japan, at the Memorial Dinner commemorating 100 Years of the birth of Gozo Shioda Kancho (the founder of Yoshinkan Aikido) and 60 Years of Yoshinkan Aikido, Sonny sensei received a Special Achievement Award, in recognition of his lifetime contribution to the development of Yoshinkan Aikido outside Japan – the first of its kind awarded to an international Aikido Master not of Japanese origin.

Sonny sensei’s career reaches another milestone by becoming the first foreign instructor to be graded to 7^th Dan black belt and Level One Instructor Certificate by Takeno Kancho in October 2016.
