When people talk about Japanese guitars, the conversation usually turns to Fender Japan, Ibanez or ESP. But Japan also has a deep bench of bass builders whose instruments are trusted by top session players and touring bassists. Here are five Japanese bass brands worth knowing, with an overview of each one, what sets it apart, and a closer look at a representative model, based on each maker’s official information.

1. ATELIER Z
According to the company, ATELIER Z traces back to 1989, when Kokichi “Johnny” Motohashi founded DAY’S CORPORATION, the company behind the ATELIER Z brand. From the start, it developed instruments together with leading Japanese bassists, beginning with Tomohito Aoki. In 2019 the company took the name ATELIER Z Guitar Works. Official site: atelierz.co.jp.
What Sets ATELIER Z Apart
- Built with working bassists. Its models were developed through feedback from professional players, starting with Tomohito Aoki.
- Active circuits. ATELIER Z became known for active basses, and later added passive models and the “j note” line.
- A Jazz Bass foundation. Much of the lineup builds on the Jazz Bass shape and sound, refined for modern stages and studios.
Representative Model: ATELIER Z M#245

The M#245 is ATELIER Z’s take on the orthodox Jazz Bass. The company describes it as combining vintage-style clarity with a clear, defined attack for slap playing. Under the hood, a Bartolini XTCT preamp with ATELIER Z’s Spectrum Boost works with two in-house JBZ-4 pickups.

2. Sugi

The NB5 is Sugi’s five-string “Night Breeze.” Its concept, in Sugi’s words, is passive control, good resonance and high playability. It is offered in 33”, 34” and 35” scales, and the official page highlights its solid low-string image.
