An ultra-detailed digital illustration of a neon-lit cyberpunk martial arts studio interior. A narrow corridor in a futuristic Japanese city, blending traditional kanji-inspired signage with high-tech elements. The left wall is lined with vending machines and illuminated panels; the floor is glossy, wet tile reflecting pink, magenta, and blue neon lights. On the right is a long counter with stools, a cash register, and a wall plastered with posters and flyers. Overhead, warm pendant lights mix with cool neon, and blue holographic screens glow in the back. The color palette emphasizes vivid pinks, purples, and cobalt blues. The scene is cinematic, game-like, and slightly moody, with sharp details, high dynamic range, and a painterly 3D-rendered look. No people. The mood is sleek, atmospheric, and futuristic, reminiscent of Blade Runner and anime-inspired cyberpunk.
