Aiichirou Nitori (Kouki Miyata)

Kouki Miyata (宮田幸季), born in Yokohama, Japan, on 9 October 1972, is a Japanese seiyuu whose credit as Aiichirou Nitori links him to the anime franchise Free!. Under that role, his voice work is associated with the series' character songs, cast recordings, and other vocal material released around the franchise. Rather than a separate solo recording career, this credit is best understood as part of Miyata's anime-related vocal work. For fans of Free!, Aiichirou Nitori is the name that connects the character to the performer behind the voice, and that makes the entry useful for finding cast-focused releases and related audio from the series. It also places Miyata within Japan's long-running seiyuu and character-song culture, where voice actors often appear on music and vocal releases tied to anime productions.
