Which is the Japanese original badminton racket?

Japan's racket is mainly yonex, and its technology is still the first in the world, although it is sponsored by a few national teams. Other brands such as Gosen, Kunbu, Kawasaki, etc. They are not used much, and they are probably not much better than victor. Lining is not recommended, the quality is average, the technology is average, and it is particularly expensive to sell. I hate profiteers who cheat people's money under the banner of domestic products.
