This Japanese manufacturer is made and produced by Tsubasa Onishi, the 2004 and 2010 4A World Champion. As a 4A (off-string) player himself, he is particular about making off-string yo-yos that are easy to use and competitive, so although the lineup is small, he has released models that are so well-made that it is easy to understand why Onishi continues to fight at the forefront even after many years. The manufacturer's first product was the "W Wing" released in 2012 after a long development period. After that, they released the "Balk", which features an ultra-wide body. Both are produced domestically, and not only are the yo-yos themselves designed, but they are also designed to accommodate detailed settings, making them the ultimate goal based on BWW's unique theory and experience. With manufacturing that is not influenced by trends, they will be a weapon that will meet the expectations of any player.
