OxT is a Japanese music duo formed in 2015 by Masayoshi Ooishi and Tom-H@ck, known for anime songs that sit between J-rock, J-pop, and anison. Since their debut in 2016, they have built a clear identity around energetic guitar-driven arrangements, memorable hooks, and songs that fit anime openings especially well.
The duo first reached wider recognition through their contribution to the opening theme for Nobunaga Concerto, and that connection to anime has remained central to their profile ever since. OxT is often searched by fans looking for anime songs, anime openings, and the artists behind some of the most recognizable theme tracks in the scene.
Musically, OxT are known for balancing polished production with catchy melodies and a performance style that emphasizes impact and energy. Their sound sits comfortably between J-rock and anime song traditions, which has helped the duo stand out among artists working in anime-related music.
In addition to their studio work, OxT have maintained a solid presence in the Japanese music scene by collaborating with various artists and participating in anime-related events. In 2025, they also collaborated with MYTH & ROID to produce an Overlord anime 10th anniversary song, and a live music video for the project was streamed later that year. Their catalog continues to reflect that mix of accessibility, musical punch, and anime tie-ins, making OxT a familiar name for fans searching for the artists behind anime themes.
