Japan Jet Ski Boating Association came to end by finalizing the last championship in 2020. Kawasaki, who supports the particular association since the rider/racers ride only Kawasaki Jet Ski, has decided on an internal policy to change its structure from 2021. The content is not "the race is sponsored by the manufacturer", but "the manufacturer participates in the race". So after 2021, JJSBA will be dissolved. However, the Kawasaki factory team is back. JJSBA closed its 37-year history in yesterday's race. Photo courtesy: Seiji Uchihashi (Uchi Images)
