Amrita Custom Guitars is a boutique Japanese luthier brand launched in January 2011 and based in Tokyo's Bunkyo Ward. The name "Amrita" is taken from the Sanskrit word for "nectar" or "elixir of immortality," reflecting the shop's view that well-built guitars outlast their players. The brand operates under a "Player's Vintage" concept — instruments that reference the construction and voicing of guitars built from the mid-1950s through the early 1960s, updated with modifications intended for modern professional use.

The lineup centers on handmade electric 1960s-style models as a regular production range and custom-built acoustic guitars, alongside a preamp D.I. in their audio equipment offerings. A signature material choice is pre-1969 Brazilian rosewood (Jacaranda / Hakananda) that has been naturally dried for decades, used for acoustic backs and sides and for electric fretboards. Amrita's Tokyo showroom, Amrita Studio, operates by appointment and is set up for extended hands-on evaluation of the instruments.
