yuhaku

Founder Tomohiro Nakagaki studied architecture and also pursued painting under the name “Yuhaku.” After working in shoe design, he began making leather goods on his own.

In 2006 he opened the atelier “ameno spazio” in Yokohama, making custom leather items while researching dyeing techniques. Those experiments led to a signature method inspired by painting.

In 2009 he launched the original brand yuhaku and reorganized as Yuhaku Inc. The brand frames color as its core and states it continues to evolve its hand-dye craft and train makers.

The dyeing process focuses on the interaction between base leather and pigments, with repeated trials to reach the intended tone. By layering colors and polishing the surface, yuhaku aims for gradients with clarity and depth.

Product categories range from wallets and business bags to card cases, belts, shoes, and care items. Materials include cow leather, cordovan, crocodile, and more, with each series offering a different feel.

yuhaku operates direct stores such as the Yokohama flagship, the Ginza Gallery, and the Osaka Shinsaibashi store, and it also works with department stores and other retail partners. Repair consultation and maintenance guidance are available for long-term use.

Gradients built by layering dyes by hand

yuhaku describes a process where one finished color may be created by layering 4 to 8 dyes, sometimes switching between many shades within the same color family. The surface is then polished to tune clarity and depth.

A design approach that lets color lead

The brand speaks of “subtraction” in design so the gradient can stand out. By working with each hide carefully, it aims to preserve natural marks while bringing out richer tones.

A dyeing method designed to avoid wastewater

Dye is taken onto cloth and applied directly to leather, a method described as producing no waste liquid and no dirty water. The brand also states it uses dyes with very high safety among commonly available options.

Series and materials for different moods

Collections include Veratula, Du Monde, Diamant, Cobweb, and more. From water-dyed cordovan by Radel Ogawa paired with hand-dyed gradients to exotic leathers, the look changes with each material and series concept.
