Naniwa Honzome Hand Dyeing is a traditional Japanese dyeing method, of which products are mainly produced in Sakai and Kashiwara, Osaka Prefecture. Osaka was a large producing center of Japanese hand towels called tenugui since the Edo period (1603 – 1868), and Naniwa Honzome was developed in the Meiji period (1868 – 1912) to mass produce patterned tenugui. The dyeing method called chusen is done by applying resist paste onto the cloth based on the pattern, then folding and repeating the process, and finally pouring in the dye. The traditional colors and appearance can only be created by this unique hand dyeing method, and these techniques have been passed down from generation to generation as Naniwa Honzome up to this day.
