Founded in 1699 (Genroku 12), a bonito flake specialty shop in Nihonbashi. Its tagline is "This country's flavor, starts here." The site places large Hiragino Mincho headings on an unbleached base color #f8f8f5, with body text set in Hiragino Kaku Gothic at line-height: 2.0. Vermilion red #e7190a appears only in the logo, current state, and hover underlines.
