Rota wheels are sold in Japan, and they all have JWL/VIA markings. They started off manufacturing OEM wheels in Japan and still do. They are based in the Philippines, who do you think their major market was going to be?? JWL is a requirement of the Japanese government and has nothing to do with retailers.
However, JWL certification is carried about the manufacturers themselves so take it with a grain of salt, but if wheels being sold are found not to be compliant the manufacturers can be fined.
Of course Volk uses a different process, but they are in a tiny minority of wheel manufacturers in the world producing wheels that way.
I encourage you to do your own research...
