ZIZAIZ
BY IZUYOSHI — APPAREL PARTS SINCE 1934Made freely. Made to connect.
Made freely. Made to connect.
Garment parts are never seen. That is the rule of our trade.
For 92 years, Izuyoshi has handled buttons, zippers, interlinings and linings.
From that knowledge, and from our own factory,
came the brand ZIZAIZ.
T-shirts, towels, bags, blankets.
Because we know every part, we can make them freely.
Team goods, company novelties, or one piece made just for you.
Whatever you want to make, it can start here.
The T-shirt is only one of them. Towels, bags, blankets, key holders. One team takes each from planning and sewing to delivery.

Izuyoshi was founded in 1934 in Fukuyama, Hiroshima, a town of textiles. For 92 years we have worked on the inside of clothes. Our parts are in many brands’ garments, and our name is on none of them.
We know the parts, and we can make the product. So we decided to do it under our own name. That is how ZIZAIZ began.
It is not a slogan. “Jiyu-Jizai” means “freely, at will”. With 92 years of parts knowledge and a factory of our own, it describes what we can actually do.
Buttons, zippers, interlinings, linings. We have handled the 50-plus parts of a garment for 92 years.
A wholly owned sewing factory. From T-shirts to blankets and bags, from planning to delivery, in one place.
A team-logo patch, commemorative embroidery, a customization of your own. Whatever you want to make, freely.
In 2018 we opened a wholly owned sewing factory in Pinghu, Zhejiang, China. Now we handle everything from sourcing parts to sewing ourselves. Prototypes are made in the sample room on site.
Fabric is cut along the pattern. Accuracy here decides the accuracy of the sewing.
A line of more than 40 machines. Wholly owned, so we see inside every step.
Before shipping, every piece passes through a needle detector.
Ordinary black clothes lose a little colour with every wash and every day in the sun. ZIZAIZ black stays black.
Cross-section of a single fibre.
The black goes into the fibre before the yarn is spun, so it stays black through washing and sunlight. Test results and the Makuake record are on the detail page.
Fabric, heaters, down, patches. We combine parts to make products of our own. Prototypes are made in the Pinghu sample room.
A carbon-nanotube heater inside. Machine washable, and buttons turn it into a poncho.
675FP down with a heater and optical fibre that glows across the back.
Solution-dyed black, layered with a heat shield.
Fukuyama, home of our head office, is a denim town. That fabric, made into a tote.
A denim cap with a single leather patch.
A down jacket, shrunk to fit in your palm.

From picking fabrics and parts off the shelf to meetings, inspection and shipping, one team takes care of it all.
As a trading company for garment materials, we have handled these parts for 92 years. ZIZAIZ grew out of that knowledge.
