From Nagoya to Philadelphia.

A Legacy of Excellence

Murase Kabanko is a Japanese leather workshop founded in 1957, synonymous with Randoseru excellence for four generations. Based in Nagoya, Japan, their master artisans are revered for creating "heirloom quality" pieces that are as much a work of art as they are a functional tool. Each bag is the result of a rigorous 150-step assembly process, combining traditional heritage with contemporary style.

The Philadelphia Connection

Zen Quality Backpacks was founded by Andrew Brenner after a New York Times article on the Japanese Randoseru sparked a lasting curiosity. That piece led him to Murase Kabanko — a four-generation atelier whose commitment to durability and quiet craft matched exactly what he wanted to bring to the United States.

Today, we are the exclusive US partner for these iconic silhouettes. Whether it's a child's first-grade journey or a professional's boardroom career, we believe the tools you carry should tell a story of quality that lasts a lifetime.
