Shonosuke Hijirisawa (聖澤庄之助 Hijirisawa Shonosuke), also known as The Mean Professor and "Hagechibi", is a recurring background and guest character appearing in Osomatsu-kun and Osomatsu-san.

He is usually unnamed in Akatsuka's original works, but received the Hijirisawa name in the -san adaptation where is he is used often as a gag.


This character is often depicted as a self-employed man, whether as a shopkeeper or criminal.

He is somewhat similar in appearance to the Come Come Hotel Owner in his design, but still considered a distinctly separate character in some sources like the Koredeiinoda website; mainly bearing a nose where the Come Come Hotel Owner lacks one, though that could have been in error from how his design was interpreted and inked.

Personality & Characteristics


Shonosuke is an older man with a basketball shaped head, big ears, small nose, a rectangular unibrow, a single buck tooth, and two mustaches pointing downward. He usually wears a brown business suit with a blue tie.


He is usually depicted as a random and cryptic figure, used for whatever purpose he is needed for in a story.


He is a crafty and creative type of man in some of his appearances, such as disguising himself in a dog suit with the intent to rob a house, or working with a myna bird to fly him around to steal.

At other times, he's an average guy of few or no words, working as an assistant to others or seen with his own job. When he hears of Iyami's death (actually a scam), he at first acts mournful, but is actually pleased that his childhood bully has finally died.


Now christened "Shonosuke", he is often a silent figure, mostly appearing as a gag in skits. Unlike the NEET sextuplets, he is employed and a figure of a higher enough status to attend a prestigious matchmaking party.

Otherwise, him not having much of a personality and his unusual nature would be the whole joke behind him. However, he and his 16 brothers are shown to become frustrated at the nonsensical and incomprehensible opening speech at the invitational and attempt to impulsively rush out. They also make the mistake of mocking Iyami, which results in their deaths.

In the second season's first episode, he is the one to introduce Iyami and Chibita to the Matsunos' "half-assed" fame and their more expansive home. He quickly vanishes through the season, and the previous season's "Hijirisawa Family" setting is discarded in favor of ultimately revealing him to be King Enma.



As an unnamed background character, his presence is often minimal with few connections to others, besides being a criminal that menaces them or a businessman of a sort.

One of his more memorable roles comes in Iyami's scheme to make money by faking his death. This man reminisces on how he was bullied by Iyami for his bald and short appearance, being mockingly called "Hagechibi" ("bald dwarf"). He later arrives at the wake, but is disturbed by Iyami emerging from the barrel after being stung by a bee. He is then seen getting revenge on Iyami's "ghost" later by beating him up, after Iyami attempts to ambush him at night.


As a gag on the banned first episode of the series, the prologue of episode 19 reveals Shonosuke Hijirisawa to be the eldest of a set of identical brothers much like Osomatsu. But instead of being sextuplets, the parody goes further, having the Hijirisawa brothers be heptadecuplets (seventeen), with all their given names ending in -nosuke. The heptadecuplets appear twice more in episode 25, and in a gag illustration in the PASH fanbook for the series.

He is often associated with Jyushimatsu as well, due to Jyushimatsu declaring the Shonosuke statue in the first delivery skit to be his "heirloom", which he refers to Shonosuke as again at the end of the Iyami Kart race.




Episode Appearances

Shonosuke/Episode Appearances


  • While mostly absent as a background character design in the 1988 series, he does briefly appear in the ballet recital audience in episode 4. This is likely due to his role as the Mean Professor, as the audience is also composed of characters from other Akatsuka series and other old manga (as Fujiko Fujio's Q-taro is seen).
