Kaminari Guitars is a Yokohama, Japan–based builder specializing in hand-made reproductions of vintage electric guitars and basses, along with effects pedals, pickups, leather straps, and its well-regarded line of oxygen-free copper instrument cables. The company operates out of a flagship store in Naka-ku, Yokohama under Onkyo Shokai, and its instruments are built in Japan and the USA, with guitar manufacturing historically tied to the Dyna factory (the builder behind many Fender Japan models).

The catalog spans original designs such as the Liquid series and the K-LQ and K-YB model lines, along with artist signature and collaboration instruments. Kaminari's cable line — including the K-GC series guitar cables and matching bass, ukulele, and acoustic variants — pairs Japanese-made OFC conductors with Neutrik plugs and has become a staple among Japanese session and touring players.

The brand has notable ties to the Japanese rock and pop scene, with associations to Motohiro Hata, Masafumi Gotoh of Asian Kung-Fu Generation, Yu Suto of TENDOUJI/TenTwenty, and Daiki Tsuneta of King Gnu, the latter of whose bandmates are also known users of Kaminari cables.

Kaminari has 7 products cataloged on Equipboard, including Solid Body Electric Guitars, Miscellaneous Guitar Parts, and Instrument Cables. Their gear is featured by 2 artists, with the strongest followings in Rock. Notable users include Naoya Ogura and SUNAO.
