Makoto Furukawa is a Japanese voice actor and singer who voices Saitama, the bald, deadpan hero at the center of One Punch Man, delivering the character's signature bored line reads.
Furukawa voices Saitama, a hero who has trained himself into such overwhelming strength that every fight ends in a single punch, leaving him chronically bored and searching for an opponent who can actually challenge him. The role calls for a flat, understated delivery that plays against the show's over-the-top action, a tonal balancing act that became one of the defining voices of 2010s anime comedy. Furukawa has stayed in the role across every season and film since the series began, making Saitama's low-key cadence instantly recognizable to fans.
Furukawa also voices Miyuki Shirogane in the romantic comedy Kaguya-sama: Love Is War, Taiju Oki in Dr. Stone, and Tabito Karasu in Blue Lock, and he played two takes on Sherlock Holmes, first in Moriarty the Patriot and later in The Tale of the Outcasts. He left his former agency, Space Craft Entertainment, to go freelance in 2018, signed with the label Toy's Factory that same year, and launched a solo singing career under Lantis with the single "miserable masquerade."
