Katsuhisa Hattori is a Japanese composer known for blending classical music with anime soundtracks. He's best recognized in the West for his work on Argento Soma and Hiroyuki Morioka's Seikai series, though he's composed for plenty of anime films, TV shows, and OVAs beyond those standouts. Born in Tokyo, Hattori has built a career straddling both traditional composition and the demands of anime production.
