"Jidai" is a brand and project that takes unused materials and materials for prototypes, adds new designs and ideas to increase their value (i.e. upcycles), and turns them into works of art and products.

"Jidai" is run by waji, a manufacturing group that produces leather wallets and small leather goods. Waji interprets one of the goals set out in the "SDGs" (Sustainable Development Goals) adopted at the United Nations Summit in September 2015, "Responsible Consumption and Production," in their own way, and strives to create products that customers truly want.



This series uses fire hoses as materials, made from recycled fire hoses that were actually used by the Sakai City Fire Department in Osaka Prefecture and that had exceeded their designated service life. The inside of the fire hose is made of rubber, while the outside is made of fiber and reflective material that are highly resistant to abrasion and heat.

By utilizing the characteristics of the material in the design, we have repurposed the fire hose from its role of "protecting our lives" into an item that can be used in everyday life.

Reflective tape adds an accent (Green Modern only). Keep you safe on dark streets at night.

This is a tough fire hose with a rubber coating on the underside.

Soft washable leather

This ID card case is made from upcycled fire hoses that have outlived their useful life and black leather.The color scheme of each creates a classic, mature impression.
Available in four basic yet expressive colors

Fire hoses are about 2mm thick and are lined with rubber to allow for the transfer of large amounts of water.

This upcycled bag was created as an item that combines the width of the hose with a stylish design that is easy to incorporate into your daily life, with a size that makes the most of the hose's width, and colorful fabric and reflective material on the outside.

Furthermore, the genuine leather used is the same high-quality leather used for leather jackets, selected from a leather tannery that is used by high-end brands, and is dyed with a special dye that can be washed with water.
Although it cannot be washed completely, it is extremely resistant to the weaknesses of leather such as hardening and water stains even when wet.

You can also unsnap the rivets and wear it around your neck so you don't have to wear it over your head.



You can store small items such as keys with chains, meal coupons, and tickets.

The clip is removable.

This ID case is made entirely by hand, from the main body to the neck strap and even the small rivets. Its charm lies in the warmth and care that can only be found in a handmade product, something that mass-produced plastic cases cannot offer.

Each case is crafted with meticulous attention to detail, and is not just a simple "employee ID holder," but is also designed with ease of use in mind, elevating it to a comfortable everyday work tool. Not only the combination of materials, but also the "attention to detail of the hands" behind it is another reason to choose this case.

For those who just can't get enough of a plastic case, this ID case offers a different option than ordinary ID cases, with the strength of a fire hose and the quality of genuine leather.

It blends naturally with both suits and casual attire, adding a touch of style to each. Whether you're in a business setting where you need to look neat or in a casual setting where you have more freedom, it will add a touch of individuality to your neck.

Fire hoses that have finished their service still show signs of having been used on the scene. Even the scuffs and dirt give them a unique charm. These traces of time are the charm of upcycling.

Materials that we don't come into contact with in our daily lives are breathed new life into. This process seems to overlap with the "cherishing of things" that the Japanese have cherished since ancient times.

Not only is it great for yourself, but it also makes a great gift for birthdays, anniversaries, Christmas, Mother's Day, Father's Day, Respect for the Aged Day, etc.
