Loud kei (ラウド系) is a Japanese "loud rock" movement that fuses the heaviness and aggression of metalcore, post-hardcore, and nu metal with the melody-first sensibilities of J‑rock/J‑pop and, at times, the theatrical aesthetics of visual kei. It is characterized by down‑tuned guitars, double‑kick drumming, breakdowns, and screamed vocals alternating with soaring, catchy choruses. Many acts weave in electronic elements (synth arps, EDM drops, vocoder/Auto‑Tune) and tight pop songwriting structures, resulting in music that feels both intensely heavy and anthemic. Live shows emphasize high energy, crowd participation, and a strong visual identity.

Visual kei is a Japanese rock/metal-centered movement defined as much by its theatrical, gender-fluid visual presentation as by its sound. Bands employ elaborate makeup, dramatic hairstyles, flamboyant or gothic costumes, and stylized stagecraft to create a total art experience that fuses music and spectacle. Musically, visual kei spans hard rock, heavy/speed metal, punk/post-punk, new wave, and gothic influences, often blending melodic hooks with virtuosic guitar work, dynamic arrangements, and emotionally charged vocals. Lyrical themes commonly explore romance, decadence, existential angst, fantasy, and nostalgic longing, while arrangements may incorporate strings, synths, or piano for cinematic effect. Substyles like kote kei (early, heavier), Nagoya kei (darker, post-punk/goth-leaning), and later softer or pop-inflected variants illustrate its breadth and evolution.
