A lot of Japanese companies leave piles on the table. One often unnoticed reality of Japanese imports and exports, at least in modern days, is that Japan as a whole has total double standards on those, requiring over the top perfection for imports but exports are almost on take it or leave it basis. Even Nintendo products are at barely acceptable levels if the standards for imports were applied to e.g. en-US editions. It's a miracle that Japanese products have substantial sales volumes and good reputations at all. It's quite unlike Chinese engineering of today.
