Haru Amano is a Japanese male voice actor primarily known for his work in adult games and drama CDs. Information regarding his broader career in mainstream anime is limited, with his professional activities being most prominently documented in adult-oriented media.

One of his few publicly noted roles in anime is in the series Fire in His Fingertips 2 -My Boyfriend is a Fireman-. In this production, he voices the character Rei Hidaka, who is the ex-boyfriend of the heroine, Ryo Fujihashi. This role was for the "premium version" of the anime, which is a more explicit version of the series streamed online, as opposed to the standard "on-air version" broadcast on television. His performance in this capacity places him among the cast members associated with adult-oriented anime adaptations from the ComicFesta label.

Beyond this anime role, the majority of Amano's credited work is in the realm of drama CDs and video games. His drama CD credits span several years and include a variety of characters in different stories. Notable examples from his discography include the role of Kyosuke Kusaka in Dangerous Reunion ~My Friend's Older Brother~ in 2017, Ifurasu = Rizuku = Yazīdo in The Tattoo Artist and the Runaway Girl -Sumi Koi Love- in 2018, Eita Hasumi in Honey Marriage: The Secret Fake Marriage with a Black-Hearted Actor in 2021, and Misaki Kamigū in The Onmyoji's Obsessive Love Curse in 2022. He is also credited with roles in video games such as Kyoma Natsume in I Want to Be in Love With You -PLUSMATE- in 2021 and Gabriel in What's Wrong With Hell in 2023.

It is publicly known that Haru Amano is a pseudonym used by the voice actor Atsushi Tamaru for performances in adult content.
