Heirloom-Worthy Bags—Companions for a Life Carried Well –Timeless Leather Designs, Crafted in Japan

Heirloom-Worthy Bags

Designed for Decades of Carrying

At Tsuchiya Kaban, we believe the bags we carry help shape the rhythm of our days. The pieces that remain with us over time become quiet companions that anchor us in a fast-paced world.

Today, we're sharing 3 Tsuchiya Kaban signature collections intentionally designed for decades of carrying: Tone Nume, a long-time bestseller with everyday versatility; Diario, elevated minimalism with luxurious whole-panel leather construction; and TSUCHIYA Legacy, the pinnacle of our heritage leather craftsmanship.

Intentionally crafted to age naturally, absorbing the traces of the life they accompany, these collections grow more beautiful and meaningful over time—an evolution that guides our commitment to timeless design and enduring quality over fleeting trends. From material sourcing and rigorous testing to construction, finishing, and final inspection, every step of our process reflects this commitment.

We hope these timeless, enduring pieces bring everyday ease and style for years to come, and perhaps even across generations.

A long-time favorite now almost synonymous with Tsuchiya Kaban among fans, this collection is crafted from our original signature Tone Nume leather, developed 20 years ago. The highlight of this vegetable-tanned collection is the incredibly soft touch and gorgeous natural grain texture.

Meticulously infused with plenty of oil, each piece is exceptionally soft and supple, molding comfortably to your shape and movements from the moment you start using it. Developing depth and character over time, it's an ideal companion for daily life.
