In time, the Japanese tailors started producing such jackets from leftover parachute silk and other fabrics, naming them sukajan, with "suka" from Yokosuka and "jan" from jumper jacket).
Today, sukajan are almost everywhere in Japan, fashioned with embroideries featuring the original themes but also anime characters, mythological animals, Japanese patterns or writing. The originals are priced around 40,000 yen, but many cheaper variants can be found, especially around the tourist venues.
