My Japanese partner Fumio works with two factories in Japan, one situated in the middle of Japan, and the other one on a southwest island - actually the main factory. Knitting is made by machine, exactly the one you can see on the photo on the left which I personnaly took end of august 2023. The machine also is made in Japan. At the back of the machine are the coils, one of them containing the conductive yarn, with the chosen colour.
After the knitting operation, every pair will be manually checked, every little yarn which is not necessary cut with scissors. Then the label will be sewed, on a small machine by hand ths time.
Another important operation will be the steam ironing, so that every hand looks perfectly flat and similar to the other one - no detectible difference between one another. All these operations are made in the same factory.
A last inspection will be done on each pair, before it is introduced into the packaging. The last operation will be the packing into boxes, before the whole production is sent into a warehouse situated close to Tokyo.
This warehouse is the final place where products are stored. All the orders will be processed from this very place : every shop in Japan, and the big orders of the distributors from Europ and United States.
