The "2nd Ki no Kenkyukai Memorial" for Yoshigasaki Sensei took place in Haigerloch from Friday October 20th to Sunday October 22nd, 2023. As can be read on the flyer, the seminar was a joint event of five dojos. Four of them are located close together in the northwestern part of the Zollernalb district in Baden-Württemberg. They go back directly or indirectly to the Association for Ki, Aikido and Health e.V., which Bernhard Boll founded in Haigerloch-Owingen in 1985. Michael Kunst's dojo in Stuttgart was created independently.
In 2003, Bruno Maule, then 6th Dan and since 2019 the second 9th Dan of the KNK International, came from Novara for the first time to a seminar at the vhs Balingen dojo and from 2004 regularly to seminars in Haigerloch and later also to Balingen-Frommern.
