AOINEON designs, engineers, fabricates, and installs neon signs and signage that become urban landmarks — handling every stage of the process in-house.

In recent years, their work reviving neon tubing — a medium rapidly disappearing from the signage industry — as art has drawn growing attention.

Since 2020, they have organized the Great Neon Exhibition series. The 2024 edition at Tokyo Tower drew over 20,000 visitors and became a widely shared topic on social media.
