Nunomo is a small music gear manufacturer founded by Japanese designer Ryosuke Kojima, producing pocket-sized synthesizers and boutique effect pedals. The company is best known for the QUN Pocket Synthesizer and its successor, the QUN mk2 — handheld units built on the ESP32 Lyrat platform that combine virtual-analog, 4-operator FM, and granular sound generation with a 64-step sequencer and a three-track looper. The QUN's firmware is developed openly on GitHub, and the hardware is designed to be hackable, with samples, patches, and updates loaded via microSD card.

Beyond synthesizers, Nunomo's catalog includes effect pedals such as the GRAIN tremolo, the Artificial Reflection reverb, the Limbo overdrive, and the S-AMP cabinet simulator, alongside the Pocket Deck, a small customizable computer aimed at writers and tinkerers. The lineup leans toward affordable, compact, feature-dense devices rather than traditional studio gear.

Nunomo's products are sold direct through its online shop and through retailers including Perfect Circuit in the US, Beatsville in Japan, and Nightlife Electronics in Canada. The company has cultivated a following in the small-format synth and DIY electronic music communities, where the QUN line is often discussed alongside other pocket grooveboxes for its unusually deep feature set at its price point.

Nunomo has 2 products cataloged on Equipboard, including Tremolo Effects Pedals and Synthesizers. Their gear is featured by 2 artists, with the strongest followings in Rock, Blues, and Folk, World, & Country. Notable users include Steve Onotera and samuraiguitarist.
