Interesting Made in Japan late 70's model acoustic guitar. Eikosha is a rarer brand from the lawsuit era in Japan.

This Eikosha R315E has an interesting sound quality and a slimmer neck which is very comfortable to play.

Seems to be all original. some scratches and nicks including a slight crack in the bridge that seems to have been repaired at some point and is holding up great. No effect to sound or playability. (pictured)

Will come well-shipped in a non-original gig bag.

Feel free to reach out with any questions, additional pictures or if you'd like a recording of the guitar.

Overview

The Eikosha R-315 E is a Japanese-made acoustic from a lesser-known name associated with Nagoya’s musical-instrument industry. Eikosha-branded guitars appeared during the 1970s, making the brand part of the broader vintage Japanese guitar story, though the R-315 E’s exact production dates remain undocumented.

Build Materials and Quality

The R-315 E follows a traditional dreadnought design, with a natural finish, contrasting dark pickguard and light-colored body binding. Dot fingerboard markers and a decorative soundhole rosette complete its classic styling; specific wood species and solid-versus-laminated construction have not been verified.

Sound, Tone and Playability

The R-315 E’s six-string dreadnought format places it in the familiar tradition of acoustics used for strumming, flatpicking and vocal accompaniment. That body style generally favors fullness and projection, although there isn’t enough documented information to establish a distinctive tonal profile or neck specification for this particular model.
