Flex Co., Ltd. (Representative: Izumi Kumasaka, Headquarters: Sagamihara, Kanagawa), operator of the original pajama brand 'Pajamaya IZUMM' (https://www.pajamaya.com/), has launched a new series of pajamas using their original 'Air Pile' fabric.
This product is the result of bringing together the best of Japanese spinning, fabric development, and sewing technologies. However, due to shifting domestic production environments, reproducing this exact quality in the future is extremely difficult.
In recent years, domestic products account for only about 1.4% of clothing supplied in Japan by volume—a significant decline from the approximately 50% share held in 1990 (*1).
This release highlights the current situation and the technology and passion poured into this 'potentially final' garment.

Challenges Facing the Japanese Apparel Industry
The Japanese apparel industry is currently at a major turning point.
Since the 1990s, as production bases shifted overseas, domestic production has rapidly shrunk. Furthermore, many small and medium-sized sewing factories are closing down due to long-term financial difficulties and labor shortages.
In particular, soft and delicate materials are difficult to sew, and with only a limited number of factories capable of handling them, the challenge of 'being able to make the fabric but not the finished product' has become apparent.
'Air Pile': Reached After Much Time
It was against this backdrop that our original material, 'Air Pile,' was born.
For years, we received many requests from customers saying, 'I want to wear that pile fabric again.' In response, we consulted with fabric manufacturers repeatedly and conducted numerous prototypes in search of the ideal material.
We finally arrived at this material, which combines lightness, softness, and stability.
