(headquarters in Adachi-ku, Tokyo) will release a limited quantity khaki color for its signature "Diario" series of leather goods for the 2026 spring/summer season on January 15, 2026.

TSUCHIYA KABAN's Signature Diario Series: Simply Crafted from Premium Single-Piece Leather
Leather Items That Add Flavor with Each Day of Use, Like a Diary
"Diario" means "diary" in Italian. Like a diary, these leather items freely capture your daily moments, with scratches and marks becoming flavorful pages that deepen personal character and attachment. This is a carefully crafted series embodying that sentiment.
Limited Edition "Khaki": An Elegant Beige Tone with Refined Depth and Brightness
The limited edition "Khaki" color is inspired by the 2026 spring/summer season theme of "pure and clear strength that creates everything." It's a subdued beige-toned khaki that conveys the pure richness of leather as a material while incorporating refined depth. The exquisite tone naturally blends with fresh seasonal outfits while maintaining a moderate presence that won't get lost even in monochromatic styles.
The main cowhide material is tanned with 100% vegetable tannins and finished naturally with abundant oil, so it increases in luster with use, and the khaki color gradually transforms into a deep brown tone. You can enjoy rich aging that adds flavor over time.
