Tsuchiya Kaban

A leather goods brand founded in 1965, originating from a workshop established by a Randoseru (school bag) craftsman in Tokyo.

With the mission of "creating values that will be loved over time," the company engages in the integrated planning, manufacturing, sales, and repair of Randoserus and leather products.

We value careful craftsmanship, aiming for simplicity and elegant appearance that can be loved for a long time, with Japanese sensibility and craftsmanship. 

The company operates a total of 31 stores in Japan and overseas, including the Nishi-Arai main store and the Karuizawa Kobo store, both of which have our own workshops. The founder, Kunio Tsuchiya, was selected as a "Contemporary Master Craftsman" by the Minister of Health, Labor and Welfare in 2022 and as a "JAPAN LEATHER GOODS MEISTER (bag category)" by the Japan Leather Industry Association. 

RANDOSERU Lite Raspberry

For over 60 years since its founding, Tsuchiya Kaban has continued to make and refine 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, Tsuchiya Kaban has developed processes such as reinforcing machine stitching with hand stitching on top. The brand is 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.

Founder Kunio Tsuchiya started his bag company in 1965 in Tokyo, Japan, focusing on a singular style, the “Randoseru”.  This style of bag was adapted from a Dutch military bag in the late 1800s and became an early sign of Western Influence in Japan. 

The brand has used their learnings from the Randoseru to create a full collection of leather goods, all handmade in Tokyo by the most skilled leather craftspeople. Today the collection has more than 150 unique styles,  sold in Tsuchiya Kaban flagship stores in Japan, Taiwan and Hong Kong and also available on their websites.
