Osomatsu Wiki

Karamatsu Matsuno (松野まつのカラからまつ Matsuno Karamatsu) is a character in the series Osomatsu-kun. He is one of the sextuplets.

Although his place in the order of the sextuplets was ambiguous and not of importance in early media, he is established as the second-eldest in more recent works, most notably his counterpart in the 2015-2018 spin-off Osomatsu-san.

His name derives from that of the larch tree, known in Japanese as 唐松 (karamatsu).


Though not able to be visually distinguished from his brothers as a child, Karamatsu is set by Akatsuka as the "carefree, happy-go-lucky" type of the six in the character notes and this carries through to later descriptors, although puns on "kara"/emptiness are also added as well.

Personality & Characteristics

Child (-kun)


As with his brothers, Karamatsu has short, dark hair with two cowlicks sticking up in the back.

He is most often seen wearing the three-buttoned uniform shirt, pants, and running shoes, wearing a shorter-sleeved short and shirts in the summer. In the Comic BomBom and Takeshobo reprints of -kun, he is often associated with the color red, even appearing with his shirt in that color on a cover. This was also reflected in the April Fools' joke for the Osomatsu-san website.


Karamatsu is a cheerful and carefree young boy said to have the most energy. Yet, he is also described as being energetic because of his bravado/"empty spirit" (karagenki). He is a bit of a crybaby and often winding up with the worst luck of the brothers, or getting another brother into trouble along with him due to his impulsive ways.

He can be eager to fight like any of the others, but can wind up a scapegoat and vulnerable in situations, and his impulsive nature leads him to get injured in brawls [1], if he doesn't simply run away crying in fear (such as the boxing match against Knock-Out Tsuyoi) [2]. When shown to wrestle against Osomatsu in one story, he is too easily defeated and thrown to the ground [3]. However, he was once able to evade Chibita's wrath by falling over to "play dead"[4].

Karamatsu also has somewhat of a large appetite, easily being able to eat all the family's rice for the day but with a resulting stomachache[5]. Compared to the others, he can also be considered a bit tidy and orderly, as he dutifully fans off his overheating X-1 robot when it is shown suffering from having to do all his homework [6] (however, the 1966 anime changes this to have Karamatsu simply eating and ignoring the robot as it studies).

He is also noted to not be too intelligent (playing on the term karappo, "empty"), to where it's questioned if his head and body are in fact entirely vacant, and his wallet is also often empty or containing little cash of value, with him coming third place (20 yen) to Osomatsu and Jyushimatsu in one story [7] (Osomatsu having absolutely nothing). However, in another instance he is shown to have some more money saved up, making him the brother with the second-most savings (310 yen to Ichimatsu's 400) [8]

This boy has no clue how to play cards[9], but can easily sew a giant stocking in a Santa-capture scheme[10], and seems to be a more artistically-inclined brother who tries to show off painting to Totoko (though this is sabotaged by Osomatsu)[11]. Another story has him tasked with taking care of a goldfish, which he seems to care deeply for to the point of angrily force-feeding Iyami a bowl of karashi in revenge for having eaten the fish[12].

Early on, Iyami mistakes his name as both being Kuzumatsu and Kasumatsu [13]. When licked by a scientist, it is stated that his skin tastes "spicy" (karai)[14].

Teenager (-san movie)


After age 16 to up to age 18, Karamatsu developed chronic acne on his face and carried a more worried and subdued expression constantly. He was shown to dress in the usual gray blazer and green plaid pants that were the uniform of Akatsuka High.


In the movie, it is shown he was a more timid young man from age 16 to 18 as he attempted to find his individual place in the group, but was troubled by his siblings' changes and wanted to mediate their whole situation (only to meet with failure).

His path to becoming a dramatic sort is sealed further in place by his future self handing over the sunglasses, lying to him that he'll have a girlfriend.

Adult (-san)

His distinctive characteristics are that he has thicker eyebrows, he wears blue as his casual wear and often has the sleeves of his hoodie and shirts rolled up to his elbows, with the exception of his blazer top for formality.

One of his signature outfits is a leather jacket with a skull on the back, a black leather belt with a skull buckle, a grey tank top underneath, blue jeans and brown boots, with the outfit topped with sunglasses. His most prominent accessory is his blue sunglasses, which his brothers break frequently. He has several of his clothes and other objects bedazzled in the first season, such as entirely sequinned pants and glittery yellow boots, and also enjoys having his face printed on clothing items.


The adult Karamatsu is shown to be confident and full of energy and "charisma", yet is often oblivious and clueless to what is actually going on around him. He tends to take everything presented to him very, very seriously, and often speaks in a drawn-out, poetic fashion.

He desperately tries to be cool using his old-school razzle dazzles and black leather jackets, in an attempt to capture the hearts of any of those he assumes to be his admirers. These attempts, more often than not, backfire horribly. Karamatsu often speaks in confident one-liners that are meant to make him sound cool and awesome, but little to none of these lines are actually entertained by others and are usually simply ignored, much to his dismay. He always seems to bounce back in the end, however, showing his determination and dedication to the ever-confident Casanova front he puts on. His brothers usually call him "painful".

Apparently, his brothers could care less about him, as evidenced when they did not bother rescuing him when he was kidnapped by Chibita in Episode 5A. This, alongside his other laughable antics, marks him as the most prominent comic relief character--he is even described by his voice actor, Yuichi Nakamura, as appearing "just for laughs."

Karamatsu earns more "respect" in the second season, even with some episodes focusing on him (while in contrast, Todomatsu takes up his former position of being ignored and pushed around). In Episode 35, Karamatsu is revealed to actually be timid and will do as told if he's put under even the tiniest of pressure. He claims it to be because he's "the nicest person in the world", only for Choromatsu to deadpan that he really is just easily intimidated. Karamatsu has mixed feelings over how his brothers treat him, bawling in the presence of Choromatsu about how mean they are to the point that he wants to kill them at times.

As evidence of his shyness, his deep voice becomes higher when nervous; this could mean that either his voice genuinely gets higher when under pressure or the higher voice is his "real voice".

He is derogatorily referred to as "Kusomatsu" ("shit matsu", "Shittymatsu") by brothers on different occasions, particularly Ichimatsu.



As children (-kun)

Among his interactions with the other brothers in the manga, Karamatsu could be said to be closest with Todomatsu, with the two being seen together the most and both sharing the tendency to impulsively get involved in a fight only to suffer for it (as in the Smog Boss story). Todomatsu is shown to get upset from being lead into trouble by his older brother, or complaining about having to go into a place he hates like a bathhouse.

In "Osomatsu-kun after 40 Years", Karamatsu continuously bothers another brother through the story who may be Todomatsu or Jyushimatsu; this brother becomes upset at him, but there is nothing that can be done even 40 years later.

In total, this duo is openly used about 10 times through the manga where both can be identified.

Totoko Yowai

As children (-kun)

When attempting to impress Totoko during the autumn season, he opts to paint with her, only for Osomatsu to get in the way.




Osomatsu-kun (manga)

"Osomatsu-kun Grows Up"

The beer advertisement story entertains a possible future for Karamatsu, 25 years after the series.

At age 35, Karamatsu has married into a greengrocer family but complains of how his wife nags him and is the more dominant one. He seems to regret getting married due to this. He is shown to have stubble, and wear a cap over his head.

Foreign Names

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

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

Language Name Origin
Cantonese (Hong Kong) Cung Je Saam Cung (松野三松) Translates back to "Matsuno Sanmatsu"; "Third Pine". He is considered the third son in the 1988 series dub due to being third in their mother's original role-call.
Korean Yuk Cheondung (육천둥) Given name Cheondung means "thunder"; 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

Karamatsu was usually voiced by Keiko Yamamoto in the 1966 show, save for occasions where Fuyumi Shiraishi had to understudy as him.

In the sextuplets' cameo in the 1969 Ataro anime by Toei, however, Yamamoto did not reprise as the boys were treated as more of a unit and Yamamoto already was handling the lead role of Ataro. Instead, Masako Nozawa voiced him along with the other five.

In the 1988 show, he was usually voiced by Mari Mashiba. However, there were occasions where Mashiba would be unavailable for a line of dialogue or even the character's entire scripted lines, leading to understudying of her sextuplet. In such instances, Megumi Hayashibara, Rica Matsumoto, or Naoko Matsui could be heard.

These episodes contain examples of the above situation:

  • "The Genius Iyami's Morphing Drug!" (Karamatsu was voiced by a different actress, Naoko Matsui, for a scream in the karashi sequence. This is due to the fact the scriptwriter did not specify which brothers got attacked except for Choromatsu, but then would specify a few of them in the scene after. Thus, the boy who gets the karashi in the eyes may not sound like a "Karamatsu" in the first scene, but sounds like him shortly after)
  • "Chibita the Wandering Gunman" (Matsumoto covered the Karamatsu lines due to Mashiba being busy with Hatabo)
  • "Great Detective! Hatabō" (Hayashibara understudied for two lines, in scenes where Mashiba was busy voicing Hatabo. Matsumoto can also be heard in a line due to this circumstance)
  • "Dad, Quit Smoking" (Hayashibara mistakenly voiced one line due to the fact it was originally scripted for Todomatsu, but had been crossed off and relabeled "Karamatsu" by the final recording draft and the miscommunication wasn't caught by her in time)
  • "The Fairytale of the Acromphalus Island" (Matsui for one line, due to Mashiba being unavailable. Another off-screen line was not voiced in the episode due to this, but appears voiced in foreign dubs)
  • "Beware the Raid" (Hayashibara for two lines, due to Mashiba being unavailable or busy as Hatabo, though his usual voice is present later)
  • "Beware! The Detective Chibita" (Matsui)
  • "The Journey of Shame!" (Matsumoto for one line, due to Mashiba voicing Hatabo in the same scene)
  • "It's Mito Komon Hatabō" (Matsumoto, due to Mashiba being required to voice Hatabo in a major role in the episode)

Although Mashiba has reprised her role for later game appearances (except for the 2012 CR Osomatsu-kun, where Yui Shoji voiced all boys), Yuuichi Nakamura provides the voice of all iterations of Karamatsu in -san, no matter his age.

  • 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.
  • According to the third DVD boxset of Ataro, Keiko Yamamoto had used the alias "Emiko Suzuki" for a time for her roles as Karamatsu and Choromatsu in -kun due to her already playing the lead role in the anime Fight! Osper and issues with her agency[15]
