It is with great sadness that we announce the passing of Dr. Kazuo Ishikawa.

Dr. Ishikawa (respectfully referred to as Ishikawa-sensei) made significant contributions to ISPGR over many years. His research focused on balance control, dizziness, and vestibular compensation, consistently striving to integrate basic and clinical sciences. Ishikawa-sensei’s involvement with ISPGR dates back to the 1983 congress in Houston. A highlight of his contributions was undoubtedly his role as a congress chair for the 2013 Akita meeting, which he successfully organized despite the challenges posed by the 2011 earthquake that had forced its postponement.

Ishikawa-sensei was an outstanding researcher, beloved leader and boss in the Posture and Gait research community, both in Japan and internationally. His presence and guidance will be deeply missed.
