Osomatsu Wiki

Jyushimatsu Matsuno (松野まつの 十四じゅうしまつ Matsuno Jūshimatsu) is a character in the series Osomatsu-kun. He is one of the sextuplets.

His name derives from 十姉妹 (jyushimatsu), the Japanese name for the Bengalese finch. However, besides being spelled with the kanji for "pine" (松), the characters for "fourteen" (十四) are also substituted.

His place in the order of the sextuplets was ambiguous and not of importance in early media, other than leaving him assumed to be the youngest brother at times due to falling last in some orders.

However, he has been established as the second-youngest son in recent works, most notably his counterpart in the 2015-2016 spinoff Osomatsu-san


In Akatsuka's original manga settings, Jyushimatsu is listed as the quiet sextuplet, gentler and a bit more reserved in comparison to the other five. However, later official descriptions by Fujio Pro instead characterize him as the loudest, noisy and talkative brother, and able to sing as well as his namesake.

The CR Osomatsu-kun pachinko game takes from both of these descriptions, attempting to resolve any contradictions by saying that he has a quiet personality but loves to sing.

Personality & Characteristics

Child (-kun)


Jyushimatsu's appearance differs very little, if at all, from that of his brothers.

In the Takeshobo reprints, he was assigned purple as a theme color and even appears wearing it on a cover. However, for the April Fools' joke on the Osomatsu-san website, the -kun era Jyushimatsu was assigned green.


Jyushimatsu is a kinder, friendly, and thoughtful type of boy, tending to avoid roughness if he can and crying easily. But this does not mean he is never complicit in fights and trouble, and he can participate in plenty mischief and unreasonable pranks (such as creating pitfalls, or putting dandruff in shaved ice). He can also be a bit eccentric in such ways. Out of the savings the brothers hold, he is often in possession of 14 yen though this can also vary upon a setting.

As he is fairly obedient, he can be easily coaxed into a situation by his brothers. Unfortunately, this obedience also makes him very gullible and weak to others' harm. At times, he'll wind up late for a plan as he'll instead take part in actions that seem natural to him. In the story "Our Rooms are Cool", he confesses to Iyami that he's insecure of not standing out among the sextuplets (as his name "is never called first"), with his presence being the weakest and him becoming weary of the world.

In Iyami's first formal appearance, he can't get Jyushimatsu's name right and instead refers to him by Jyunimatsu ("twelve matsu").

Teenager (-san movie)


After age 16 to age 18, Jyushimatsu is shown to have constantly spaced apart, narrowed eyes and a bitter expression, though this flips to his usual happy face when he's alone and unnoticed. This furthers his visual differences that were already shown when he joined high school, when he had a single cowlick instead of a pair like the rest.

He wears his high school uniform shirt hanging out, and has his zipper undone on his pants which he also lets hang loose.


In the movie, it is shown that this incarnation of Jyushimatsu attempted to differentiate more from the group at age 16, taking on a tough and crude persona that masked a more happy and whimsical self that would eventually fully break free after his graduation. This evolution is sealed in place by the interactions between the 20-something Jyushimatsu and that past self.

When attempting to act as a delinquent, this Jyushimatsu would pretend to smoke invisible cigarettes and act out in other outlandish ways, down to dropping his pants and letting his bare buttocks be exposed.

Adult (-san)

He is usually seen with his mouth wide open, smiling, with his tongue visible. He also has one cowlick. He is usually seen wearing a yellow hoodie with stretched sleeves, blue swim shorts and white socks. At home, he wears yellow slippers.

Like the rest of his brothers, he occasionally can be seen wearing a light blue blazer, gray slacks, and black dress shoes when they all attempt to dress formally.

In the Jyushimatsu Matsuri episode, it is suggested that Jyushimatsu's current look came about at age 16 (though he was also shown to be constantly smiling as a newborn, standing out from his brothers in being awake while they slept). This is elaborated on in the movie, though in a different and extended way for how he achieved his current look and attitude.


Jyushimatsu is the strange one and the most child-like of the Matsuno brothers. He is generally happy, energetic and over-excited almost all the time, and is rarely seen in a serious state. According to Ichimatsu, Jyushimatsu also has trouble blending in with other people due to his extreme child-like personality and his bizarre attitude. This is to the point where the others speculated that he may have the most hidden darkness among them, and even Ichimatsu confessed to believing so until he realized "he's just Jyushimatsu" and cannot necessarily be classified (being even in his own "genre").

Despite this, he can display the most kindest among the sextuplets through his outgoing personality, and was willing to help Ichimatsu find ESP Kitty. However, if it is cold or something else sets him off, Jyushimatsu's anger and other unreasonable behavior can be most dangerous. In other times, he will simply do whatever he wants with no logic to it except whatever may be natural in his own mind.

In Christmas Osomatsu-san, it is established that Jyushimatsu makes it a point to stay up and wait for Santa every Christmas, and has done so since he was a child. But this is for a much less innocent purpose than what his brothers may think; his purpose of waiting was so that in the end, he could finally get the chance to tie up Santa and capture him.

As part of his unusual nature, Jyushimatsu can display the most reality-warping and "anime physics" examples out of the sextuplets, down to spontaneously multiplying himself into many copies or generating muscle growth.

Osomatsu-kun (manga)

"Osomatsu-kun Grows Up"

25 years after the events of -kun, another idea of an adult setting is detailed in this Big Comic advertisement for Sapporo Black beer.

Jyushimatsu, now 35, has been employed as a doctor and can be differentiated by his Chaplin-style mustache. However, Osomatsu believes that he isn't that good of a doctor, since he was unable to save their father from choking on a fish bone. Jyushimatsu retorts that it was Todomatsu's fault for selling him the fish with the bone, but Todomatsu directs the blame to Choromatsu.

Although Osomatsu is specified to be single out of the group of brothers, Jyushimatsu's marital status is left ambiguous (along with that of Choromatsu and Todomatsu).

Foreign Names

Note: Full names in other Southeast Asian dubs are listed in the Eastern standard order.

Jyushimatsu appears with these names in dubbing and translations of the franchise outside of Japan.

Language Name Origin
Cantonese (Hong Kong) Songye Liusong (松野六松) "Matsuno Rokumatsu"; "Sixth Pine" as he fell sixth in the original role-call.
Korean Yuk Bindung (육빈둥) Given name Bindung means "hollow"; surname means "Six".

The renaming in Korea only applies to the -kun dub aired there; his name is retained in the -san dub aired in 2016.


Voice Acting

Jyushimatsu, along with Osomatsu, was one of the few sextuplets to have a solitary voice in the 1966 anime. He was consistently portrayed by Mie Azuma throughout the episodes.

However, for cameos outside the series such as in Toei's Ataro anime, he and his brothers were treated as more of a unit and voiced by a single actress (Masako Nozawa).

In the 1988 anime, he was voiced by Naoko Matsui, as a secondary role to her major one of Totoko. On some occasions, Matsui was either busy voicing Totoko or unavailable for another reason, leading the Jyushimatsu role to be handed off to another actress temporarily for a line or for all his dialogue in a script. In such circumstances, it was usually Rica Matsumoto who handled Jyushimatsu, though Mari Mashiba and Megumi Hayashibara could also be heard infrequently.

These episodes display such instances:

  • "The Genius Iyami's Morphing Drug!" (Hayashibara is heard twice within the karashi sequence, making her seem to be the unaccounted-for Jyushimatsu)
  • "Sheeh! I'm a Ballerina" (Hayashibara, for his only line. This is due to Matsui wrapping her session work with Totoko's lines and leaving for the day, necessitating that line to be covered by anyone else that could)
  • "Chibita Became a Mama" (Mashiba, in a line where Jyushimatsu thinks Osomatsu stole their milk. This is due to Matsui being Totoko in the same part)
  • "The Shinigami Salesman of Hell" (Matsumoto for a brief line, due to Matsui being needed for Totoko in the same scene)
  • "The Contents of the Head Have Been Replaced" (Matsumoto in his final line, due to Matsui being Totoko in the next scene)
  • "Great Detective! Hatabō" (Matsumoto, again for necessity of Matsui being in the same scene)
  • "Iyami's Body is Full of Germs" (Matsumoto, due to Matsui only being needed for Totoko's scenes)
  • "A Dinosaur Egg Omelette!" (Matsumoto, due to Matsui voicing Ichimatsu beforehand. However, this may also be due to both verses in the script being accidentally marked "Choromatsu", and the Spanish dub had Choromatsu speak twice due to this, even if the lines were mimed by two different boys.)
  • "Iyami's Bogus Beach House" (Hayashibara, Matsumoto, Mashiba)
  • "A Fake Doctor Makes an Easy Profit" (Matsumoto)

Though Yui Shoji covered all the brothers in the 2012 SanThree pachinko game, Matsui would briefly reprise as both Jyushimatsu and Totoko for the 2017 -kun pachislot game.

In Osomatsu-san, Jyushimatsu is voiced by Daisuke Ono in all of his ages and incarnations.

Jyushimatsu/Osomatsu-san Episode Appearances


  • Like the other sextuplets and members of the Matsuno family, his surname was initially not set in place and had appeared early on as Yamano. By 1964, it would be set as Matsuno, along with his birthday of May 24th.
  • Books like the Anime Encyclopedia and other secondary English sources often had trouble spelling Jyushimatsu's name due to the authors not being certain if the kanji for four was meant to be read as "Shi" or "Yon". This may lead to him being seen as "Jyuyonmatsu" or "Juuyonmatsu". The kanji for ten being alternatively read as "To" could also sometimes result in a "Toshimatsu".
  • As the romaji reading for 十四 can be both "Jyushi" or "Juushi" to represent the long vowel, an early appearance of Jyushimatsu's Jyushiko role had her name spelled "Juushiko" instead before it was corrected in later skits.
