Of course your right... When I was a kid, all the cheap junk toys came from Japan
The problem with Chinese bearings is that they do not follow in legal terms the same definitions for bearing type, that the rest of US, Europe, Japan, ect follow.
They can make a bearing and sell it to whatever standard they want to... and often do...
It's possible that under the NSK brand and hopefully NSK supervision, they are making a good product, time will tell.
I just don't want experiment with Chinese bearings in my builds.
If I did I would just get a Wiseco or Hot Rods kit and call it good.
