Asia Engineer (エイジアエンジニア)

Formed in 1998, Asia Engineer (エイジアエンジニア) is a Japanese four-member hip-hop group that includes SHUHEI. The group's music blends rap with pop-friendly melodies. Its sound is defined by clear hooks, group vocals, rhythm-driven flow, and strong melodic writing, while favoring accessible production over a hard-edged underground approach. That balance places Asia Engineer within Japan's pop-rap and urban music scene. The group's melodic, upbeat sound also extended to anime. Asia Engineer performed "Eternal Pose (エターナルポーズ)," the ending theme for One Piece. There, the group brought the same emphasis on catchy choruses and vocal character to an anime work shaped by mainstream pop sensibilities and hip-hop energy.
