Kojima Jeans are a made in Japan denim known by those in the know. Its quality has been held in high regard both domestically and globally. So much so that there are overseas premium brands that buy fabrics from Kojima and request product development support.


History of Kojima Jeans

Have you heard that Okayama prefecture is known for the Momotaro (the peach boy) folk tale? The Kojima district, located in Kurashiki of Okayama prefecture has been known as a city of textiles during the Meiji Period (1868-1912). Leveraging this technology, Kojima was the first place in Japan to manufacture denim. This was in 1960. Now, the area is well-known as a “Holy Place for Denim Jeans”.    


The Virtues of Kojima Jeans


The appeal of Kojima Jeans are the high quality that comes from using traditional Japanese technology. The main price point is a bit expensive at 10,000 yen to 25,000 yen per pair, but wouldn’t you want to own at least a pair of the best denim? If so, then Kojima jeans are your perfect choice. There is also some rare vintage denim with a few pairs in existence all around the world. These cost several million yen. It is said that these are in the best condition for denim that is over 100 years ago. As you can see, in Kojima, there are many treasures that collectors would die for.


The Secret of Kojima Jeans: Indigo Dying


How can they make such high quality jeans? One of the secrets is the dying technique of indigo dying called “aizome”. This method was widely used during the Edo Period (1603-1868). The material is soaked in a dye that is made from fermented dyer’s knotweed, wrung, oxidized to fix the color. By repeating this over and over, the color becomes deeper and deeper. Thus, the fabric dyed using this indigo dying technique is resistant to fading of color and lasts for a long time. 

Also, the blue of the indigo dye is called Japan blue or Kojima blue around the world. It is a very popular color. Sometimes, the color of the uniform for Japan’s national soccer team and the blue in Ukiyo-e paintings of Utagawa Hiroshige and Katsushika Hokusai are also referred by this name.
