At the end of the day, parts like tuners, bridge, pots, knobs etc are always replaceable. The MIJ Tokais are excellent guitars, in terms of the quality of the body, neck, action, finish etc. The hardware is not the best in the world (nor should you expect it to be for the money), but the overall quality of what cannot be changed is superb.
Having said that, I have owned a MIJ Tokai LP as my number 1 guitar for about a year, and all I have changed is pickups (which didn't really need to be changed, but I'm a natural tinkerer).
I'll be honest, I don't know where a lot of the parts of the MIJ Tokais are produced - probably in China (most things are these days, even on top quality stuff), but the overall effect of the guitars, and the quality of the way it has been put together is well worth the money.
When I was last looking at guitars, the only other similar quality guitars, for similar prices were from Washburn - may be worth looking at too.
