The History of Japanese Denim: From 1965 Big John to Global Selvedge Dominance (2025)
The history of Japanese denim began in 1965 when Maruo Clothing (now Big John) in Kojima, Okayama, produced Japan's first domestically made jeans using imported Cone Mills American fabric — and within 50 years, Japan went from importing American denim to producing what collectors and industry experts widely consider the highest-quality selvedge denim in the world. The arc spans postwar GI surplus jeans, the founding of Kojima's mills, the 1979 birth of the Osaka Five, the 1990s vintage revival, and today's role as the last place on Earth still operating pre-automation shuttle looms at commercial scale.
What Is the History of Japanese Denim?
The history of Japanese denim is the 60-year story of how a Seto Inland Sea port district called Kojima — already famous for cotton, indigo, sail-cloth, tabi socks, and school uniforms — pivoted to jeans manufacturing in the 1960s and ultimately preserved the vintage selvedge denim tradition that American mills abandoned. It is built on three foundations: postwar Japanese fascination with American workwear, Kojima's pre-existing indigo and cotton expertise, and a generation of obsessive founders in Osaka and Okayama in the 1970s and 80s who refused to let 1950s production methods die.
At Japan-Denim.com, we trace the lineage of every brand we carry back to this history. Understanding when Big John released its first jean, why the Osaka Five formed, and how vintage Toyoda shuttle looms survived is essential to appreciating why a pair of Japanese selvedge costs $250 and lasts a decade.
Background: Postwar Roots (1945–1964)
Denim arrived in Japan with American GIs after WWII. Surplus jeans sold in Ueno, Tokyo, and at Ameyoko market became coveted symbols of American freedom and youth culture. Through the 1950s and early 1960s, demand for jeans in Japan was met almost entirely by imports — used Levi's, Lee, and Wrangler jeans shipped from US distributors.
By the early 1960s, Japanese apparel makers saw the opportunity. Kojima, with its strong indigo dyeing and cotton textile heritage from the Edo and Meiji periods, was the natural production hub. Maruo Clothing (founded 1940 in Kojima) had already pivoted from tabi socks to school uniforms to work pants when, in 1965, it released the "Canton" line — Japan's first domestically produced jeans, sewn from imported Cone Mills American denim.
Deep Dive: The Eras That Built Japanese Denim
1965–1972: The Birth Era. Big John's Canton launches in 1965. Edwin, founded in Tokyo in 1947 as a used-denim importer, begins making its own jeans in 1961 but ramps up domestic production through the late 1960s. In 1969, Big John commissions Kurabo Mills in Okayama to produce KD-8 — Japan's first denim fabric woven inside Japan. By 1972, Kurabo is operating the first domestically produced selvedge denim line.
1973–1978: Full Vertical Integration. Big John releases the M-Series — the first jean fully designed, woven, and sewn entirely in Japan. Kojima becomes a denim ecosystem with dye houses (Kuroki, Kaihara), weavers (Nihon Menpu, Collect), and finishers all within a few square kilometers. Japan's first synthetic indigo dye line is also commercialized in this period.
1979–1989: The Osaka Five. Studio D'Artisan founder Shigeharu Tagaki opens the brand in Osaka in 1979, kicking off a movement obsessed with replicating pre-1960s Levi's quality. Through the 1980s, Denime (1988), Evisu (founded 1991 by Hidehiko Yamane), Full Count (1992), and Warehouse (1995) join — collectively becoming "the Osaka Five." Most produce in Kojima despite their Osaka identity. Crucially, this generation reactivates retired vintage Toyoda G3 shuttle looms originally used for school uniforms.

1990–1999: Vintage Revival Goes Global. American collectors discover Osaka Five reproductions. The 1990s Japanese denim boom is fueled by hyper-accurate replicas of pre-WWII Levi's 501XX. By the late 1990s, Japanese-made denim is sold in select American boutiques and trades on collector forums at premium prices.
2000–2010: Momotaro, Iron Heart, Samurai, and the Heavyweight Era. Momotaro Jeans launches in 2006 with hand-painted back-pocket battle stripes and Zimbabwe cotton. Iron Heart (founded 2003 by Shinichi Haraki) pushes into 18oz–25oz heavyweight denim aimed at motorcyclists. Samurai Jeans (1997) and Oni Denim (founded c. 2002) push texture and slub yarn to extremes.
2017–Present: Last Mill Standing. Cone Mills' White Oak plant — the last American selvedge mill — shuts down in December 2017. Japan, through Kaihara, Kuroki, Nihon Menpu, and Collect, becomes effectively the only commercial source of premium selvedge denim worldwide.

Frequently Asked Questions
Q: When were the first Japanese jeans made?
A: The first domestically produced Japanese jeans were Big John's "Canton" line, released in 1965 by Maruo Clothing in Kojima, Okayama. They were sewn from imported Cone Mills American denim. The first fully domestic Japanese jean — woven inside Japan — came in 1972–1973 with Big John's M-Series using Kurabo-woven selvedge fabric.
Q: Who are the Osaka Five and why do they matter?
A: The Osaka Five are five Japanese denim brands — Studio D'Artisan (1979), Denime (1988), Evisu (1991), Full Count (1992), and Warehouse (1995) — founded in Osaka and dedicated to recreating pre-1960s Levi's quality. They reactivated vintage Toyoda shuttle looms and defined the modern selvedge denim aesthetic that brands worldwide now follow.
Q: Why did Japan preserve vintage shuttle looms when America didn't?
A: After WWII, Japanese mills built large shuttle-loom inventories for school uniforms and military fabric. As Japan modernized to projectile looms in the 1980s, the older Toyoda G3 looms were stored rather than scrapped. Osaka Five founders in the 1980s and 90s reactivated them specifically because the slower, narrower weave produced superior fades. American mills, meanwhile, fully replaced their shuttle looms by the early 1980s and eventually shut down domestic selvedge production entirely with Cone Mills White Oak closing in 2017.
Q: Is Japanese denim actually better than American denim today?
A: For premium selvedge specifically, yes. After Cone Mills' White Oak shut down in December 2017, Japan became effectively the sole commercial source of authentic vintage-style selvedge denim. Kaihara, Kuroki, Nihon Menpu, and Collect mills produce fabric used by both Japanese and American premium brands today.
Q: What was the first Japanese-woven denim fabric?
A: KD-8, produced by Kurabo Mills in Okayama in 1969–1972 on commission from Big John. It was the first denim fabric woven entirely inside Japan and laid the groundwork for Kojima's vertical denim supply chain.
Q: How did Japanese denim become globally famous?
A: Through the 1990s, American collectors traveling to Japan discovered Osaka Five reproduction jeans and brought them home. The combination of internet forums (Superfuture, Styleforum), collector blogs, and select American boutiques carrying Japanese denim made it globally famous by the mid-2000s. The Cone Mills White Oak closure in 2017 cemented Japan's position as the world's selvedge capital.
The Bottom Line
Japanese denim's history is the history of obsession — Kojima's 60-year refusal to abandon shuttle looms, Osaka's 1980s mission to perfect pre-war Levi's, and a generation of mills that quietly preserved every step of pre-automation denim production. From Big John's 1965 Canton to today's $1,500 hand-loomed Momotaro Gold Label, Japan has become not just a denim country but the denim country.
