INDEN-YA
Koshu Inden lacquer on deerskin from Kofu, Yamanashi — a craft tradition 400 years in the making.
INDEN-YA Co., Ltd. is the producer of Koshu Inden — a traditional Japanese craft technique in which urushi lacquer patterns are applied to tanned deerskin (鹿革), creating a surface combination unique in world leather craft. The company is based in Kofu City, Yamanashi Prefecture, where Inden (印傳) has been produced for over 400 years. The deerskin provides a soft, lightweight, and durable base material; the urushi lacquer patterns — applied through a resist-printing process using stencils — create raised, tactile designs in a range of traditional Japanese motifs (arabesque, paulownia, hemp leaf, dragonfly) that are visually distinctive and do not fade or crack over decades of use. INDEN-YA produces wallets, coin purses, and small leather goods in Koshu Inden for daily use.
PROFILE Company & Brand Story
Inden (印傳) is a craft technique in which urushi lacquer patterns are applied to tanned deerskin using resist-printing methods — a process that has been practiced in Kofu, Yamanashi Prefecture for over 400 years. The combination of materials is unusual: deerskin (鹿革), which is prized for its exceptional softness, light weight, and durability, receives urushi lacquer patterns applied through stencils that create raised, tactile designs on the leather surface.
The Inden process begins with carefully selected and tanned deerskin — a leather with a distinctive fine grain and exceptional suppleness. The tanning process preserves the skin's softness while providing stability for the lacquer application. Urushi lacquer — Japan's traditional lacquer derived from the urushi tree — is then applied through stencil-cut patterns in a thick, precise layer. The lacquer cures to form a raised surface design that is permanently bonded to the leather.
The resulting material has properties unique in leather goods. The deerskin base is extremely soft and comfortable to hold — softer than most calfskin, with a distinctive slightly textured surface. The urushi patterns are visually striking and dimensionally present — they can be felt as well as seen. And unlike surface finishes or printed patterns, urushi on deerskin does not crack, peel, or fade with decades of daily use. The lacquer and leather age together.
INDEN-YA has been the principal producer of Koshu Inden since 1582, maintaining the techniques and stencil patterns that define the craft. The traditional motifs — arabesque (karakusa), paulownia (kiri), hemp leaf (asanoha), dragonfly (tombo), and others — carry centuries of Japanese decorative history. New colorways and occasional contemporary designs extend the range while the core craft remains unchanged.
Koshu Inden wallets and coin purses are among the most distinctive Japanese craft goods available internationally — recognizable in form and impossible to replicate outside the specific material and technique combination. A Inden-Ya wallet carried daily for a decade develops a patina in the deerskin while the urushi patterns remain visually intact: a material combination that rewards long-term ownership.
Koshu Inden — urushi lacquer on deerskin, a 400-year Yamanashi craft
Inden is the application of urushi lacquer patterns to tanned deerskin through stencil-resist printing — a craft practiced in Kofu, Yamanashi for over 400 years.
