Made in Japan

Our Japanese craftsmen create each product by hand with intricate attention to detail and exceptional quality.


A Tsuchiya Kaban Signature Style

For over 60 years since its founding, Tsuchiya Kaban has continued to make and refine our Randoseru. The Randoseru was created as a sturdy and beautiful bag that Japanese elementary school students could continuously use every day for 6 years. It has been regarded as universal and durable and is now enjoyed by many people regardless of age or nationality.
Made from 150 parts in 300 steps, the Randoseru keeps its beautiful box shape even after many years of use because each side's core is made with a double structure of bonded resin and sponge. For parts like shoulder straps that undergo a lot of strain, we have developed processes such as reinforcing machine stitching with hand stitching on top. We are very conscious of designs that fit the body and achieve comfort while carrying it on the back by evenly distributing the load. In particular, the cushioning on the back is U-shaped to ensure a good fit and prevent heat from building up. It's also waterproof, making it simple to clean. It fits a 13" laptop and metal fittings on each side to attach items such as key chains.

Cordovan is a rare and luxurious material

The leather lies in its intoxicatingly soft luster and silky smooth touch. It is a premium leather tanned from the under hide of the horse rump.

Comparing each material's characteristics


The leather's surface has a bumpy pattern pressed into it, making it both hard to scratch and hard to notice scratches when they do occur.

About Cordvan


This leather is known for being light and soft so it easily fits to the body from the first use while also remaining durable.

Long-lasting durability

Even after using for a long time, the core material in the box-shaped sides has a double structure of resin and sponge glued together. This allows it to absorb impacts well and maintain its beautiful boxy shape for many years. The durability of the straps, which are prone to wearing out, is ensured in ways such as reinforcing with layers of leather hand stitching.

Combines breathability and flexibility

Designed to conform to the body and reduce load, the U-shaped padding that comes into contact with the back allows for the passage of air and prevents heat from building up, making it comfortable to carry on the back.

Strong against water and easy to care for

Waterproof leather is used so you don't have to worry about rain and can clean it a wet cloth.

Thoughtfully Compartmentalized

More storage than meets the eye to hold tablets, notebooks, bottles, and more, all while keeping its boxy shape. There are also gusseted compartments and zippered pockets, useful for holding phones, wallets, and accessories.

Have fun customizing it your own way

Photos can be filed away in the back of the flap or pockets. It also has hooks on the left and right so you can enjoy decorating it as you like with scarves or key chains.
