Thambu was awarded his eighth dan by Kyoichi Inoue, former director of Yoshinkan Aikido in November 2015.

On 8 July 2012, he was awarded an honorary doctorate by the Asia Pacific Open University for his lifelong commitment and contribution to the martial arts.

In acknowledgment for his dedication to Aikido, Thambu was awarded his seventh dan by Shioda Yasuhisa, the former head of Yoshinkan Aikido in December 2007, and was promoted to the rank of “Shihan” in October 2008.

Since 2000, Thambu has taught widely outside of Australia, generally at the invitation of younger teachers in other countries. Thambu continues to teach from his school in Melbourne, Australia, frequently hosting students from overseas, of whom, many are aspiring teachers staying for extended periods, coming from countries such as the United Kingdom, Poland, Malaysia and Indonesia. Including annually at the Shudokan UK’s Summer school with Robert Mustard and Ken Robson.

In 1993 Thambu became the last person to be graded by Yoshinkan founder Gozo Shioda, before his death in mid-1994. At only 32 years of age, he became the youngest non-Japanese to be awarded a 5th Dan in Yoshinkan Aikido. This record has since been passed onto Thambu’s former student, Jon Marshall, who was awarded 5th Dan in 2006 at Yoshinkan Hombu.

In 1983, Thambu first travelled to Japan to further his Aikido training. Whilst in Japan, he trained at the Yoshinkan Hombu dojo in Koganei. While living in Japan he received instruction from teachers including Gozo Shioda, Kyoichi Inoue, Takafumi Takeno, Tsutomu Chida, Hitoshi Nakano, and then assistants Jacques Payet and Tsuneo Ando. From this time onwards, Thambu focused on the modern Yoshinkan syllabus, including knowledge from his earlier training.

Thambu was the first person to teach, and disseminate Yoshinkan Aikido in Australia. On his return to Australia from Japan in 1983, he established his first premises at 308 Saint Georges Road, Thornbury in Melbourne (Australia). This became the first of two permanent homes for his school.

Thambu returned to Japan numerous times in the years from 1983–2000, generally training a few weeks at a time, testing and/or demonstrating at the annual All Japan Yoshinkan Aikido Demonstration.

In 1980, Thambu emigrated to Melbourne, Australia to undertake tertiary studies. After reportedly being unable to find an Aikido school with a training ethic to equal his experience in Malaysia, he began teaching Aikido.

Thambu was the third youngest of eight children from Malaysian Tamil heritage. He began his training in 1972, at the age of 11, training under his uncle, Thamby Rajah. Thamby Rajah is credited as the first Malaysian to grade to black belt in both Aikido and Judo. Internationally famous martial artists were frequent visitors to his uncle’s school in Seremban, Malaysia. Among these were Donn F. Draeger, a prolific martial arts historian and researcher who wrote over 30 books on Eastern martial arts. Draeger was expert in Judo, Karate and Jōdō and was the first non-Japanese to be ranked Menkyo-Kaiden (teaching certificate) in the classical system of Shintō Musō-ryū Jodo.

Joseph ‘Joe’ Haridas Thambu (24 March 1961 in Seremban, Malaysia) is a teacher of Yoshinkan Aikido, currently ranked 8th Dan, Shihan.
