I agree.
In Japan, whether cheap or expensive, the quality of products is all at a satisfactory level. You can buy cheap stuff for 100 yen shops, but the quality is quite good.
In other parts of asia, like Korea or Taiwan, you often have to spend more money to get the same quality. If you are looking for some cheap stuff, the quality is really bad. It's either expensive or cheap, good or bad, and there is no middle.
