Kōrai (光雷), meaning “Light & Thunder”, is a conceptual energy drink brand inspired by Japanese minimalism and futuristic aesthetics. The brand aims to capture the essence of energy, clarity, and strength through a clean yet bold design system.

Energy drinks are often loud and aggressive in their branding. With Kōrai, the goal was to challenge this norm by creating a refined, minimal, and premium identity that still feels powerful. The name symbolizes the fusion of light (clarity, speed, focus) and thunder (raw power, energy).
