Hakkaisan (Hakkaisan Brewery / HAKKAISAN) Style Design System (DESIGN.md, Japanese UI)

A sake brewery in Minamiuonuma, Niigata. The site uses an extremely ascetic composition of white background, black text, zero rounded corners, entrusting almost all of its expression to typeface selection and letter spacing. Headings use Tsukushi A Old Mincho, body text and navigation use Shuei Gothic Gold L. Unusually for a Japanese commercial site, it uses almost no decorative elements (shadows, rounded corners, gradients, colored section backgrounds).
