Editing Peter Chong (section)

== Founding Kyokushin in Singapore ==
In 1969, Chong returned to Singapore and established the country's first full-contact Kyokushin dojo at a kindergarten on St. Francis Road off Serangoon Road. Because of its full-contact nature, the dojo could not join the Singapore Karate Federation, which only recognized sports karate at the time.

He attained 4th dan in 1972 during a three-month visit to Japan, where Oyama also appointed him Chairman and Chief Examiner for Southeast Asia and the Middle East. He reached 5th dan by 1975.

In 1978, Chong expanded the school into a formal society called the Singapore Oyama Karate-do Kyokushinkaikan (SOKK). By the 1980s, SOKK operated multiple dojos, including branches in the Police Reserve Unit and various community centres across Singapore. In 1982, he co-founded the Singapore Martial Arts Instructors Association (SMAIA), eventually serving as its president.
