SUWADA (Suwada Manufacturing) Style Design System (DESIGN.md, Japanese UI)

A cutlery manufacturer in Sanjo City, Niigata Prefecture (founded 1926). Known for nipper-style nail clippers, and operates an "open factory" that shows the factory itself to visitors. The site uses a pure black page background #000000, lays dark factory photographs full-screen over it, and places white Mincho and serif type on top. It creates a screen like tools arranged in a darkroom.
