Japanese consumers would like to learn how to used things according to manual. The n=manual play bigger role in Japanese culture than other western world. To be success in Japan, you need to explain everything, I guess Japanese people would not like to think ... they just follow manual.
I found this shop in Hakata ... Those bags are made right there in the store. They are not cheap but they look well made. I would like to contact someone like this to open an online store in the US using Kiroboto.com
This game ma an idea ,,, We should modify Kiroboto enabling companies like this open a store. I will think about it when I get back.
