Tsuchiya Kaban Co., Ltd. (Headquarters: Adachi-ku, Tokyo; hereinafter referred to as 'the Company'), a leather product brand originating from a randoseru workshop, will launch its new 'Straven' series on Thursday, May 7, 2026. The series is based on the concept of 'sophisticated relaxation.'
Adorned with octagonal metal fittings symbolizing harmony and expansion as a design accent, this series expresses a beauty that naturally blends into daily life through its minimalist appearance, high-quality materials, and restrained forms, with long, flowing shoulder straps creating a relaxed feel.
The lineup includes a total of four styles: two types of shoulder bags, a 2-way one-handle bag, and a cross-body bag. All will be available at 14 'TSUCHIYA KABAN' stores nationwide and on the company's official online store.
Octagonal shape as a design accent
The octagonal form, symbolizing harmony and expansion, is used as a design accent.
Its precise shape is elevated into a modern form.
The buckle of the shoulder strap features an octagonal shape. As a subtle yet impressive detail, it adds a quiet accent to the overall appearance. The adjustment holes are also elongated ovals, creating a modern and refined look.
The original drop handle fittings, which can be used to attach charms, are inspired by the 'daruma-kan' (a type of D-ring) found on randoseru. The solid, rugged texture of the metal adds a sophisticated accent to the bag's presence.
'Semi-matte Smooth Leather' with soft firmness
The main material used is 'semi-matte smooth leather' from an LWG-certified tannery. This cowhide is attractive for its smooth appearance, soft yet firm high-quality texture, and moist feel. Its subdued semi-matte finish blends into a wide range of styles, highlighting the profound charm of the leather.
Chic colors with depth and richness
Black
A sophisticated black with a semi-matte finish that evokes an urban feel. The interior, stitching, and edges are unified in black, creating an overall chic black tone. Calm silver hardware and a foil-stamped logo on the interior complete a modern and clean aesthetic.
Dark Brown
A deep brown with a subtle reddish tint, enhancing the leather's rich texture and offering a chic yet relaxed hue. The exterior is coordinated in similar tones, and paired with calm silver hardware, creating a refined impression.
