As I mentioned earlier, an increasing number use printed names, not ori-name. Now, they are required to supply a whole package of accessory items, such as printed names, tags, paper seals, plastic clasps and bags - when you buy a dress shirt, for example, everything you get other than the shirt itself. I believe this is what is happening. Because of this, the ori-name manufacturer is expected to act as a trading company for accessory items. Yes, that's true, but since they don't manufacture those items in-house, there's a very low margin.
Profit depends entirely on volume.
Japanese clothing and apparel manufacturers shifted their production overseas quite a while ago - to Hong Kong, South Korea, China, Vietnam, Thailand, Indonesia, India and the Philippines. Most of their production is shipped to Japan, with a smaller amount exported to other markets. Among those countries, China has been accommodating an increasing share of the production. To cope with this, they are expanding their factories to increase capacity, doubling machinery and making the most of the Internet. Quality requirements are as strict as any in Japan.
