All the Youkaimatsus so far
JExcept sets that have all of them as the same youkais (Nekomata, Tanuki and the various Kitsune sets from Tabimatsu)
Pinup Poster from the Osomatsu Character Book #6 (July 2016)
A classic. The very first iteration of Youkaimatsu. Kind of hard to find since it was a bonus poster from the character book, so unless you were actively looking for the book, you wouldn’t find this.
Osomatsu - Kitsune (unknown how many tails he has but is often depicted in fan artworks as 6 or 9, 9 meaning strongest/wisest a kitsune has been, Spirit Fox)
Karamatsu - Karasu-Tengu (pun on Kara, Bird Man)
Choromatsu - Dodomeki (usually a woman cursed with long arms littered with many bird eyes because of greed. Most popular one imo)
Ichimatsu + ESP Nyanko - Nekomata (Two-tailed cat, legend says that cats who live longer than a 100 years gain a second tail)
Jyushimatsu - Rokurobi (available in two flavors. Long Neck and Floating Head. He is the former. Theorized to not actually be a youkai but created for entertainment. Also used as a literary device for a wandering soul.)
Todomatsu - Yukki Onna (Also a joke on Todo being scared stiff. Yuki Onna pull tricks on humans that usually end on the person’s death via cold. Has a harsh and soft side)
Youkai Units from The Great Youkai War event from Hesokuri Wars (November 2016)
Most popular Youkaimatsu set, this baby could get milked for miles, but for some reason isn’t. Has a lot of variants (Awakened, Darkness, Snow, Sakura and Hyakki Yagyou) and connected to a lot of other sets: Denki Mystery, Colorless Overalls, Mononoke and a bunch of others. She is the top DOGG set.
Osomatsu - Shuten-Douji (Oni Leader with a penchance for Sake, literally carrying a big ass bottle of it on his back, since he is the leader of the sextuplets and the one seen drinking beer the most)
Karamatsu - Aoandon (Summoned after 100 supernatural stories are told. Originated from the blue (ao) paper lanterns (andon) that were sometimes used to give a chilling atmosphere)
Choromatsu - Daitengu (Great Tengu, Tengus were theorized to be ascended souls, but also has its origins in a Dog Beast that looked like a comet. For some reason Dog Beast turned into Bird Man. The bird man’s beak is often anthropomorphized into long noses. Tells humanity to behave by throwing invisible stones at them)
Ichimatsu - Nine-tailed Kitsune (So wise. So powerful)
Jyushimatsu - Inugami (Dog God that possesses people)
Todomatsu - Bake-Danuki (also known as tanuki, mischievous spirits, mostly known in pop culture for their BIG FAT NUTS)
Dayon is a miko, a shrine maiden. Hatabou is an Onmyoji, an exorcist, Dekapan is a kannushi, a shrine priest. Totoko and Iyami are regular civillians
Youkai Hyakki Yagyou merchandise from Animate Girls Festival (September 2017)
One of the lesser known sets, considering that it’s just designs for a line of merch but their designs are so good? Why don’t people use these designs more often.
Karamatsu - Nine-tailed fox
Choromatsu - Shuten-Douji (A possible reference to Season 1 Episode 2 where he gets the most drunk?)
Ichimatsu - Mizuchi (Legendary Water Serpent/Dragon)
Jyushimatsu - Kamaitachi (Beast that rides on dust devils. Cuts people using it’s scythe-like nails. The wounds are sharp but painless)
Todomatsu - Ungaikyou (A haunted mirror that can be used to trap spirits. The spirits in the ungaikyou can manipulate the reflection shown on it’s reflection.)
Kitsune Servant Set from Tabimatsu (September 2017)
Ok I know I said I wouldn’t cover the Kitsune sets from Tabimatsu since there are like 5 different Kitsune sets, but this one is noteworthy cause they have secondary Youkai traits other than the regular kitsune traits.
Karamatsu - Tengu’s wings
Choromatsu - Orochi around his neck
Ichimatsu - True Kitsune (Or Nekomata’s paw?)
Jyushimatsu - Wanyudo (Flaming Wheel)
Todomatsu - I don’t know, but there’s something around his neck?
Japanese Youkai set from Shimamatsu (January 2018)
Shimamatsu was such a good game, what a shame it ended so soon. The 3D models were so cute. Edit: The two designs are from before and after evolution!
Osomatsu - Enma-san (A wrathful god in charge of judging souls in the afterlife. Resides over hell)
Karamatsu - Yamato no Orochi (Eight headed and Eight-tailed serpent/dragon)
Choromatsu - Kamaitachi (wields an actual scythe)
Ichimatsu - Youkai Catman or a Bakaneko (Catboy, furry)
Jyushimatsu - Yobuko (lives in the mountains, repeats whatevers shouted into the mountain, explains the phenomemon of Echos)
Todomatsu - Yuki Otoko (Snowman, a Yuki Onna basically)
“Inn” Osoma and Choroe from Osomatsu Season 2 Episode 17
A BUNCH OF PEOPLE REMINDED ME AND HOW COULD I FORGET THE BEST YOUKAI EVER. Osoma baby,,,, I’m so sorry..... Srsly, this skit was so good, I hope they make more skits like this where they make entirely new characters out of the framework of the sextuplets.
Osoma - A Zashiki-warashi, child spirits who live in store rooms or extra rooms, they died buried in their homes. Pranksters but meeting one is said to bring good fortunes to families. Osoma gets crossovered a lot with the other Youkai sets in JP fanart. A popular pairing is Dodomeki Chorosuke (from Denki Mystery) and Osoma also Kitsune Osomatsu (from the poster) and Osoma.
Choroe - Not necessarily a youkai, in fact in the episode she’s presented as just a regular human. But is theorized often to be a Yama-uba. An old woman banished to the mountains. She provides shelter to weary travelers (in the myth it’s just a humble shelter but you know. an inn is also considered a shelter) before eating them. In one story she eats the recently birthed baby of a woman who had to give birth in the mountains.
Mononoke from Hesokuri Wars (May 2019)
Technically they are all the same type of being, Mononoke, but they look different from each other. Mononoke can posses individuals and cause suffereing and even death. And technically they aren’t Youkais but Onryos, vengeful spirits. But Onryos can also be used to refer to youkais and truthfully I just wanna include this set cause their designs are so cool looking. This set’s attacks contain glimpses of units of other sets.
Choromatsu - Rooster/Chicken themed
Edo Rock The Great Youkai Harvest Festival from Tabimatsu (October 2019)
This set is interesting cause rather than youkai alone, they are also musicians. This set also has another set like Hesokuri called The Great Youkai NEET which is basically the awakened versions, properly showcasing more of the youkai traits.
Osomatsu - Shuten-Douji (Again, we need to stage an intervention for you damn)
Karamatsu - Karasu-Tengu (Again)
Choromatsu - Mizuchi (actually riding said serpent)
Ichimatsu - Black Kitsune (Hot Topic, Goth version)
Jyushimatsu - Frog. Just. Frog. (could be a reference to the legend of Jiraiya, the ninja who could shapeshift into a frog/ride big frogs. His mouth is cover just like a ninja is too.)
Todomatsu - Kamaitachi (could be a reference to season 1 where Todomatsu wields a scythe)
Iyami - Oni (not sure if he’s any particular oni but he does have the horns and metal club)
Atsushi - Ibaraki-Douji? (White hair and singular horn, most imporant servant of Shuten-Douji)
Promo Merch from Sega Cafe collab (September 2020)
Edit: Thank you @zenryokubatankyu for notifying me! Another set of promo youkais! You can get them by random by ordering a drink or meal at the now-defunct Sega x Osomatsu collab cafe. And the return of F6? Damn I haven’t seen you since Season 2!
Karamatsu - I’m not exactly sure but he seems like a Mizuchi, a water serpent/dragon. He also could be another legendary serpent/dragon though.
Ichimatsu + ESP Nyanko - Karasu-Tengu
Jyushimatsu - I’m not sure, at first i thought it might be a crab youkai judging from the legs, but upon closer inspection he has spider webs on his robes, so they may be spider legs instead. Could be a Jorogumo, a youkai that wields fire breathing spiders with it’s spider legs
Todomatsu - Bakaneko (I think? The veil could be the napkin a bakaneko puts on it’s head)
Ayakashi Sextuplet’s Retro Halloween Cafe merch from Web Kuji (October 2020)
Thank you @gradelstuff for telling me about this! Ayakashi are Youkai that appear above nearby bodies of water. Although the youkais they’re dressed up as (or are?) aren’t really what you would call ayakashi? Although it’s cafe themed, it isn’t actually from a cafe collaboration. These designs are merchandise meant to be won through lottery. So if say you really love Kara and Choro’s designs (I do), then tough luck buddy!
Karamatsu - Now you may think he’s Dodomeki since he’s covered with eyes, but turns out there are two other eye-relateed youkai! Mokumokuren is a youkai phenomenon where eyes appear from torn paper walls and tatami floors, initially i thought this was it given the checkered pattern he was wearing. But he might actually be a Hyakume, a youkai covered head to toe in yellow eyes specifically. Underneath those eyes is a body of flesh roughly in the shape of a man. This Youkai isn’t particularly malicious, only detaching one of it’s many eyes to follow you and survey you for criminal activiy. He might also be a BackBeard, a youkai allegedly from the US, err that would make him a cryptid I guess? A Backbeard is often characterized as a shadow with a Yellow eye with a red iris in the center. Note: Backbeard’s true origins are not known as there doesn’t seem to be any cryprid called a Backbeard, it first entered the Japanese public eye as an antogonist in the show Gegege no Kitaro. Although ever since then this “yokai” has appeared in other media and games in Japan.
Choromatsu - He isn’t exactly dressed as it (only themed as it) but the youkai he represents is the one he’s holding, a Kasa-obake, One of my favorite youkais and it’s literally iconic. Thought to be a Tsukomogami, an object that gains a spirit after it turns 100 years old.
Ichimatsu - Edit: I’m not sure but he might be a Kuchisake-Onna. In the description attached to his teaser, it makes mention of specifically his wide smile, his dos dagger and his beautiful shirt. A kuchisake onna is a yokai that wanders in the street covering her face with a mask (skull mask for ichi) and a sharp object (his dos dagger). TW GORE DESCRIPTION: She asks you if you think she’s attractive and depending on your answer she muders you with her scissors, plunging it into you OR she takes off her mask showing her wide smile, her mouth slit at the corners to her ears and asks “how about now?” and depending on your reaction she cuts you in half with her sharp object OR she slits the corners of your mouth to look like hers. END DESCRIPTION. Ichi has the mask, sharp object, wide smile and “attractiveness”. Obviously it would be inappropriate to portray ichi in the same fashion as the kuchisake onna so he was probably given the internal organ tattoos to represent the gory yokai. (internal organs usually = gore in japan). This is speculah and he might be another youkai but this is all i can think of rn.
Jyushimatsu - sailor themed Jiangshi. Jiangshi are basically Zombies originally from Chinese culture. They hop around, and crave for life force. this little jyushimatsu has taken to tomato juice instead. (Bonus: the zombie that osomatsu is in the zombie set in hesokuri wars is also a Jiangshi)
Todomatsu - Kitsune (sly fox)
“The Night Path” Youkai from Osomatsu-san Season 3 Episode 6 (November 2020)
The latest and what sparked me to make this post tbh. This set reuses the Rokurobi design from the very first Youkaimatsu iteration! Full circle yo! I like to think of this set as an addition to the original youkaimatsu, since they’re both from the primary sources.
Jyushimatsu - Rokurobi (Again)
Totoko - Amabie (mermaid with three legs? prophesized about either good harvest or an epidemic, trivia: “Amabie” trended when Covid 19 hit the world)
Hatabou - Azukiarai (a youkai that originated from the sound of something like beans being washed near a river, anyone who comes near will fall into the river)
Dayon - Nopperabou (Faceless spirits that take the form of humans. They are harmless usually, they just scare humans)
Dekapan - Kappa (Mischievous River spirits)
That should be all of them!
Osomatsu has been a Kitsune, Shuten-Douji (twice), Karasu-Tengu, Enma-san and an Oni
Karamatsu has been a Karasu-Tengu (twice), Aoandon, Kitsune, Yamato no Orochi and a Mizuchi (?)
Choromatsu has been a Dodomeki, Daitengu, Shuten-Douji, Kamaitachi, Mizuki and a Kappa (No repeats!)
Ichimatsu has been a Nekomata, Kitsune (twice), Mizuchi, Bakaneko and a Karasu-Tengu
Jyushimatsu has been a Rokurobi (twice-ish), Inugami, Kamaitachi, Yobuko, a Frog from Jiraiya and a Jorogumo (?)
Todomatsu has been a Yuki Onna (twice), Bake-danuki, Ungaikyou, Kamaitachi and a Bakaneko
You can definitely see a trend (lmao), I’m looking forward to more Youkaimatsus from Osomatsu-san!
Osomatsu-san cameo from Yokai Watch!!!
