The hardcore punk band PROLETARIART, formed in Aichi Prefecture, were captured live by the VANVAN channel during a high-energy performance at 心斎橋KINGCOBRA (Shinsaibashi KINGCOBRA) in Osaka on March 14, 2026. The footage documents the band doing what Japan’s underground punk scene does best—fast, abrasive riffs, militant rhythms, and the kind of raw club atmosphere that defines the country’s DIY hardcore circuit. Filmed inside one of Osaka’s legendary punk live houses, the clip feels like a direct transmission from the frontline of Japan’s crust-leaning hardcore ecosystem
