What is BUN FREESTYLE
'BUN FREESTYLE' is the brand name used to encompass the marine business and product services of Yugen Gaisha 231. It represents the philosophy pursued by Bunichi Watanabe, the company's president, in the field of Jet Ski Freestyle, and extends that ideology to 'products and services.'
Who is Bunichi Watanabe?
Bunichi Watanabe, also known as 'BUN,' is the maverick of the jet sports world who clinched the title of world champion in Jet Ski Freestyle.
The Road to World Champion
While typical athletes strive to improve their physical abilities and skills to secure victory, Bunichi Watanabe took a different path. He embarked on the development of the ideal machine (watercraft) that he envisioned.
Development of Competitive Watercraft
The competitive watercraft developed by Bunichi Watanabe, both to achieve world titles in Jet Ski Freestyle, are named 'Wabuzun' and powered by the 'Waz' engine.

Engine 'Waz'
It marks the moment when freestyle athlete and jet engineer, Bunichi Watanabe, came into being.
With the machine (watercraft) he developed himself, he achieved four consecutive All Japan Championships.
In domestic competitions, he secured a winning streak of 16, and further distinguished himself by becoming the first Japanese to win back-to-back World Championships in 2007 and 2008. These records remain unbroken to this day. Recognizing such achievements, he was inducted into the Hall of Fame by the IJSBA (INTERNATIONAL JET SPORT BOATING ASSOCIATION) in 2016, becoming the fourth Japanese to achieve this honor.
