As earlier said they set a high standard for themselves and those that cant handle it end it. Its kind of good from an evolutionary stand point. The weak are weeded out while the strong prosper and procreate. The samurais that failed their master often committed seppuku. World War II Japanese Kamakazi fighters flew their plans into their targets willingly. Its no surprise the highest quality goods in the world come from Japan.
Before it was really possible to buy the best from Japan. Now I rarely see products from Japan. Yes indeed, technology and production China. Now maybe Japanese products can be seen only in Japan.
