Founder: Hanshi Howard Lipman (RIP)

RIP Hanshi Howard Lipman, 1942-2024.
Hanshi Howard Lipman was 10th Dan in Kobudo, 10th Dan in Goju-Ryu (honorary) and 9th Dan in Kyokushin Karate. In January 2008, Hanshi Howard met Sensei Hokama in Okinawa and knew at once that this Sensei was the man whom he wished to continue his martial arts studies.
Hanshi Howard returned to Okinawa in May of 2008 with a group of black belts. This was the beginning of the three trips per year to Okinawa, returning in August and October that year. The trips continued over the years, with the main purpose being to learn Kobudo (weapons) to pass on to Hanshi Howard’s existing Kyokushin students to broaden their knowledge of the martial arts. At the end of the October trip, Hanshi Howard was appointed the Australian Branch Chief of the International Hokama Kobudo Organization.

Hanshi Howard organised numerous Kobudo seminars. In 2009, Sensei Hokama came to Australia at Hanshi Howard’s invitation to instruct KIMAA students. In 2011, Hanshi Howard was graded to 5th Dan (“Master”) in International Hokama Kobudo. In September 2012 Sensei Hokama returned to Australia and was involved in a weekend seminar with the KIMAA students, organised by Hanshi Howard. At the end of this seminar, Sensei Hokama graded Hanshi Howard to Renshi in Kobudo, awarding him the rank of 6th Dan (Rokudan).
In the 2015 Japan Group Tour, Sensei Hokama promoted Hanshi Howard to 7th Dan in Kobudo. It was during this trip that Hanshi Howard met Shihan Ken Ogura (8th Dan) from Sensei Hokama’s organisation.
Hanshi Howard hosted Shihan Ken for a week in November 2016, when Shihan Ken taught a seminar in Karate and Kobudo for KIMAA students, and again in September 2017 and September 2018. Hanshi Howard returned to Okinawa once again in the KIMAA Japan Group Tour 2017 for further training with Sensei Hokama and Shihan Ken. Hanshi was granted the rank of 8th Dan in Kobudo by Sensei Hokama in 2020.
In 2023, during Hanshi’s 71st trip to Okinawa, Sensei Hokama chose to honour Hanshi Howard with an unexpected 10th Dan grade for his commitment, knowledge, execution and support of both Goju-Ryu Karate and Kobudo since 2008 as Australian Branch Chief. Among his many trips to train in Japan, Hanshi has also facilitated representatives from Goju-Ryu to come to Australia to instruct aspects of this Karate style, including bunkai for kata, and Kobudo. In what became his final trip to Japan, Hanshi Howard was elevated to the most senior grade in both Goju-Ryu and Kobudo by Sensei Hokama – 10th Dan (Hanshi).
Hanshi Howard Lipman passed away in July 2024. His widow Masumi Lipman transferred KIMAA to Shihan James Sidwell as its new Chairman, as per the wishes of her late husband, and Renshi Mark Shelmerdine serving as the Head Instructor of Kobudo for KIMAA. Rest in peace, Hanshi.
