Introducing depsoa: Tsuchiya Kaban's New High-Performance Backpack Brand

Tsuchiya Kaban Unveils New Brand 'depsoa'

Established in 1965, Tsuchiya Kaban, a noted manufacturer of leather items headquartered in Adachi, Tokyo, has announced the introduction of its latest backpack brand, depsoa. The brand will roll out its first offerings for the 2027 academic year, adding to Tsuchiya Kaban's existing lines: 'Tsuchiya Kaban's Randoseru' and 'grirose'. The debut of a new shopping experience comes with the upcoming multi-brand store, THE RANDOSERU TSUCHIYA KABAN, set to open on January 31, 2026, at Cocoon City in Saitama, where all three brands' backpacks will be displayed and available for purchase.

The Concept of 'depsoa'

The depsoa brand focuses on resilience and functionality, encapsulated in its core concept: "Beyond Function ─ Progress as You Feel". This ethos encourages children to trust their instincts and dedicate themselves to their passions. The backpacks combine a durable yet lightweight construction with features that promote freedom of movement. The aim is to enhance children's energy and encourage active participation in their daily lives.

For parents and children interested in the depsoa line, catalog requests for 2027 enrollment can be made starting from October 1, with sales officially beginning on February 10, 2026.

Key Features of 'depsoa'

The depsoa backpacks are designed with several high-performance features:

- Durability and Lightweight Design: Utilizing a firm core structure, the backpacks ensure high durability while remaining light enough for everyday use. The Actlight model, featuring polyester, is particularly impressive at approximately 980g, marking Tsuchiya Kaban's lightest backpack ever.
- Ample Capacity: With a width of 12.5 cm, these backpacks can comfortably hold a child's school supplies, including tablets, without compromising weight. The artificial leather model weighs about 1,230g.
- Safety & Security Features: Each backpack incorporates waterproof materials and 360° reflective elements for enhanced visibility and safety. Additionally, a dual snap lock on the sides makes it user-friendly for young children.
