The history of denim would not be complete without mentioning Japanese denim! This is not just a story of human ingenuity, resilience, and a bit of intense passion, but also of hope. Recent years have seen the demise of many famous American mills, such as Cone Mills. On the other hand, the Japanese denim industry is still prospering, hopefully for many years to come.
Denimheads will know that the birth of Japanese denim is centered around Kojima, a sleepy town in Okayama, West Japan. For centuries, Kojima has been an important center for cotton farming. Its low-laying land was reclaimed from a salty swamp, and therefore is too salty for growing rice. In addition, Aizome (indigo dyeing) was spread in Japan. In this context, jeans seem like a natural craft for such a region, but the coast of Okayama was by no means the only region of Japan that produced textiles — it was not even one of the most famous ones! The important thing to note about Kojima’s pre-history is that local industry focused on crafts rather than agriculture.
Denim grew as an industry for several reasons. On one hand there was a shrinking market for school uniforms (which had been the main product of Kojima for decades) due to internal competition. There was also the need for supplementary income in the harsh post-war years, by — for example — taking contract work to re-cut discarded old American jeans to fit Japanese bodies. These jeans must have been a common sight at the time of the occupation, when the United States Army imported large quantities of clothing (often feeding the black market of Ameyoko in Tokyo). The sudden influx of American movies and pop culture helped the spread of this material.
Though the origin story of Japanese denim is a bit obscure, it is believed that the first domestic brand of denim was the now-defunct Canton brand. Starting in the 1960s, Canton initially used American-made jeans and subsequently started production in Tokyo with imported denim.
Maruo Clothing — now Big John, a brand still thriving today — then had an idea to solve its perpetual supply problem for jeans: Maruo would make its own denim fabric, sure to be much cheaper than American imports. Maruo Clothing had already gained success since 1968 as a maker of jeans with imported American denim. Maruo had convinced the famous Cone Mills to send them scraps, B-rolls, and leftover fabrics, which were used to start the first Big John line. Maruo Clothing took a huge gamble by completely switching to becoming a jeans manufacturer. This must have felt like an outrageous move at the time, when almost no one in all of Okayama even owned a pair of jeans! In the early 1970s, Big John asked a factory called Kurabo to reverse engineer the Cone Mills fabric. After several trials, Kurabo Mills finally managed to produce the first-ever Japanese denim in 1972, named Kurabo KD-8 (the 8 is because it was the eighth try).
What makes Japanese denim so distinctive, even now, is the use of short looms to create unique selvedge denim.
This distinctive effect is achieved by using old-fashioned shuttle looms, mostly abandoned in the US after WWII in favor of projectile looms, but imported — at very low cost — to Japan. Projectile looms are faster and therefore reduced costs, but shuttle looms create a shorter, self-sealed edge (the selvedge), and a more unique and uneven texture to the fabric.
Once considered signs of inferior quality, these characteristics started to appeal to customers in the 1970s. Enthusiasts began to revive vintage production, reintroducing denim garments as a superior product from a bygone era.
Interestingly, this revival did not start in the United States, but instead in Osaka! Starting with Studio D’Artisan in 1979, five companies (the Osaka Five) began re-adopting vintage weaving methods to craft the selvedge denim jeans of the past that had almost been forgotten by the masses.
The efforts of the Osaka Five inspired other small denim makers to not only rediscover selvedge denim, but to eventually pioneer new styles, dyes, and cuts specifically to exploit the unique characteristics of selvedge denim. Japanese denim is now a global phenomenon with the town of Kojima as the center of it all, having been resurrected from a sleepy shutter town to a tourism center for denim lovers.
Hopefully these insights into what makes denim so special, as well as so ubiquitous, have you ready to cut into your own denim for our theme month!
