What is Hohoemi no Bakudan, the Yu Yu Hakusho theme song?
Most long anime rotate opening songs by the season. Yu Yu Hakusho used one for all 112 episodes: Hohoemi no Bakudan, written and sung by Matsuko Mawatari, a singer songwriter whose bright, slightly husky delivery became the sound of the series' Saturday evenings from 1992 to 1994. The title translates roughly as Smile Bomb, and the official English version of the song, recorded for the Funimation dub, keeps that name and follows the original arrangement closely.
Mawatari was woven through the whole production's music: she also performed the first ending theme, Homework ga Owaranai, and returned across the run, while the later endings rotated to Hiro Takahashi's contributions, including Anbaransu na Kiss o Shite, whose moody video and placement across the Chapter Black era made it a fan favorite rivaling the opening. The television score itself was composed by Yusuke Honma, but the public memory of the show's music is Mawatari's voice, which is why she headlines this entry.
The song's afterlife is unusually strong for a 1992 anime theme. It has been covered repeatedly, performed at anniversary events by Mawatari herself, and it anchors the franchise's music releases: original soundtrack albums, character song collections and the Eizou Hakusho video series all orbit it. In Japan it reads as a generational song beyond the fandom, the kind of theme that karaoke catalogs never drop.
As physical objects, the original releases are modest and charming: the 1992 CD single of Hohoemi no Bakudan in its slim single case, the soundtrack albums on the era's labels, and later anniversary reissues and vinyl era compilations. None is individually rare; together they form the complete music shelf of a series whose soundtrack never fragmented across a dozen openings.
For the dubbed generation, the English Smile Bomb carries the same nostalgia charge, and Funimation's care in producing a singable English version, rather than replacing the song, is part of why the dub's reputation stayed high. One song, two languages, 112 episodes: no other major series of the era bet so completely on a single opening, and the bet is now inseparable from the show.
