Cotton has a rich history of cultivation in the Senshu area of Osaka, renowned for producing the traditional 'Wazarashi'—bleached cotton that is meticulously purified to remove impurities. Wazarashi is created by subjecting cotton fabric to a kiln burning process for two or three days under a gentle stream of water, followed by meticulous finishing of the fabric.
Established in 1911, Takeda Sarashi Kogyo has been committed to safeguarding the traditional Japanese craftsmanship of Wazarashi—an exquisite fabric known for its tactile comfort and breathability.

SaSaSa was developed as a product that seamlessly integrates into modern lifestyles while preserving and celebrating the inherent qualities of Wazarashi.
