Kobashi Studio merges Japan's finest materials with generations of craftsmanship, creating handmade heirlooms where every detail tells a story. Founder Junichi Kobashi oversees artisans who shape JIS-standard brass into sand-cast buckles, hand-bent key hooks, and vintage-style chains woven on 50-year-old machines. Leathers include three-month vegetable-tanned hides from century-old tanneries, paired with heavyweight Okayama canvas woven on antique looms. From Tokyo's cam-operated lathes to foot-stamped engravings and laser-precise markings (0.01mm accuracy), each piece blends tradition with innovation. Zippers are hand-assembled by specialists since 1957, while waxed hemp cords and government-grade nylon tapes ensure enduring quality. Whether pressed brass, hand-sliced deerskin, or Meiji-era woven cotton, every material honors Japan's artisanal legacy—crafted by multigenerational workshops to become tomorrow's vintage treasures.
