KOJIMA GENES
From Kojima, Okayama—made-in-Japan denim for everyday life.
Kojima in Kurashiki, Okayama is widely known as a denim town. KOJIMA GENES makes jeans and workwear with a strong focus on domestic production in Japan. Denim sits at the center—tough enough for daily use, and enjoyable as the fabric develops character over time. With an official online shop, support pages, and a direct store in Kojima, it’s easy to choose a pair you can live in for years.
Why We Love It
Denim can be “grown,” but getting started is simple. Decide whether you want rigid or one-wash, then plan how you’ll wear it. I rotate a heavier pair on weekends and a straight fit on weekdays. Adding a denim bag or small goods is also a fun way to bring texture into daily outfits. If you’re unsure about sizing or shrinkage, the FAQ and contact form help you narrow it down quickly.
PROFILE About the Company / Workshop
KOJIMA GENES is a denim-focused brand based in Kojima, Kurashiki, Okayama. Operated by HOOK Co., Ltd., it has continued making domestically produced jeans and workwear since the company’s founding in 1996. The brand’s identity is tightly connected to the town name itself.
Core products center on jeans, including selvedge options and a range of fits. Differences in silhouette, fabric weight, and wash/finish give you room to choose based on both use and mood. A single “standard” pair can easily become the anchor of your wardrobe.
The collection doesn’t stop at pants. Workwear-style tops, overalls, bags, and accessories are also offered, often highlighting fabric character through classic work textiles. If you like material-driven styling, there’s plenty to explore.
The buying experience is well supported. The online shop provides guides, FAQs, and a contact form. There is also a direct store in Kojima, so you can choose in person when you prefer. Multiple entry points make it easier to commit to a pair you’ll wear for the long run.
Made in Kojima, made in Japan
KOJIMA GENES is rooted in Kojima, Okayama, and focuses on domestically made jeans and workwear. The brand name carries the place itself. It’s a straightforward promise of craft and durability, designed for real daily wear.
Beyond jeans: full workwear styling
The lineup extends from jeans to work pants, tops, overalls, bags, and small goods. Starting with one pair, you can naturally build a full wardrobe around denim textures and practical details.
Collabs that expand the denim story
The brand also works with various partner companies to deliver its technique and quality in new forms. Collaborations—such as those with motorcycle-related partners—keep the workwear spirit while opening new angles.
Clear shopping support and a direct store
Shopping guides, FAQs, and a contact form are available online, making long-term purchases feel less risky. For those who want to see items in person, there is also a direct store in Kojima.
