[TSUCHIYA KABAN] New 'Dark Brown' Color Added to Waterproof Leather Backpack Series for Comfortable Business Life

Tsuchiya Kaban Manufacturing Co., Ltd. announced the release of a new standard color, 'Dark Brown,' for its 'Vainno' series, designed for urban life, under the 'TSUCHIYA KABAN' leather brand, on June 4, 2026. Designed with a refined form and convenient details, this product seamlessly transitions from business to private settings while maintaining a minimalist aesthetic. Furthermore, by using waterproof leather, it provides practicality that is not affected by weather. The harmony between the leather's deepening character and structural beauty creates a sophisticated style. It will be available at TSUCHIYA KABAN direct stores nationwide and the online store.

The 'Vainno' series allows users to enjoy the elegance of leather regardless of the weather by utilizing waterproof leather. Applying the brand's roots in randoseru (school bag) technology, the back panel uses soft cowhide with excellent moisture absorption and release properties, along with cushioning material, to ensure comfort even during long periods of wear.

The new 'Dark Brown' color features a deep hue reminiscent of high-quality dark chocolate. It carries elegance within a calm tone, blending naturally into business styles. It offers a higher grade of business style, combining classic charm with quiet strength and modern nuances. The hardware is finished in black silver, and the interior is unified in black.

The main material is 'Waterproof Fine Leather,' which maintains a high-quality texture while providing waterproof capabilities. By applying waterproof processing to the inside of the leather, it is resistant to water droplets and humidity. This allows for worry-free use during sudden rain or daily exposure to water, achieving a balance between daily practicality and functional beauty.
