Jersey Girl Homemade Guitars is a boutique guitar workshop based in Hokkaido, Japan, established in 1991 by luthiers Kaz Goto and Akiko Oda. The shop operates as a small three-person team — Kaz, Akiko, and Eiko — building roughly 12 to 15 instruments per year by hand, each treated as a one-off composition rather than a production run. Alongside guitars and basses, the team builds custom effect pedals and accessories.

The brand's catalog revolves around named, recurring body shapes that share a family identity but vary widely in spec from build to build. The Coota typically features a heavily contoured back and a vibrato system, while the Tapa is a hardtail counterpart; other recurring models include the Sonoranna, Coneysides, Gauche, and a Custom Jazz offset. Inlay work, top carving, and finish detailing are central to the aesthetic, and every instrument is sold as a unique piece rather than a repeatable model.

Jersey Girl is sold internationally through a small network of authorized boutique dealers in North America and elsewhere, and the workshop has exhibited at events such as the Holy Grail Guitar Show. The brand's reputation sits firmly in the high-end handmade boutique category, with collectors and offset-guitar enthusiasts as its core audience.

Jersey Girl has 2 products cataloged on Equipboard, including Overdrive Effects Pedals and Solid Body Electric Guitars. Their gear is featured by 2 artists, with the strongest followings in Rock and Pop. Notable users include Shigenobu Suzuki and 朝日 廉 (Asahi Ren).
