*Kuma: Kuma means bear in Japanese. The bear logo of Aikuma dyestuff comes from the name of Kumajiro Arai.
*Indigo wax: Clay-like material extracted from indigo-dyed old clothes and rags collected from farmers.
*Konya: Japanese traditional dyeing shop which dyes Noren, Kimono, Hanten, and so on. Aikuma has a strong relationship with Konya.

  • Aikuma saw development of Japan

    Here is a production license from the Meiji Government which came after the collapse of the Edo shogunate. As Japan opened its doors to modernity, Aikuma's business gradually began to grow.

  • Aikuma's New Year's greetings in 1935

    This old Annual leaflet portrays the consumption trend at that time. Because of the Sino-Japanese War, producing less luxurious clothes in darker colors such as black or navy dyes were considered favorable. Aikuma has always focused on meeting the public's demands. 

  • Aikuma survived WW2

    The first Aikuma building was built in 1928 after the Great Kanto earthquake of 1923.

    During WW2, Asakusa was attacked in the Tokyo Air Raid. It became a burnt-out area, but Aikuma survived and continued to supply its products.

  • New product development

    As much as we cherish our long history, we seek outside our conventional ways.

    For example, we developed YAMATO INDIGO, which makes dyeing easier. Starting in 1956, Aikuma News introduced such products to customers every year.
