Sun of Japan was founded in 2019 by Jakob, an optometrist based just north of Copenhagen, after years working in an industry dominated by mass-produced eyewear left him convinced Japanese craftsmanship deserved wider attention. It's a curated retailer rather than its own label, stocking Japanese-made names like DITA, Eyevan, Factory900, Masunaga, Matsuda and True Vintage Revival. The site frames the appeal as similar to Swiss watchmaking: a craft tradition built on regional pride and close attention to detail.
