Curate, connect, and discover
Ik a lot of people might feel a knee-jerk reaction to this and go "why are you making this? it's been a long time since the character was banned and went into oblivion," and that's true. However, I find that a lot of characteristics of how South Korea was written has been carried on by some Hetalia fans, which are still problematic and rooted in pro-Japanese imperialist sentiment.
Here, I'll try my best to go over some major points, starting with Korea's canon design.
Character Design
Looking at this for the first time, I felt like I was on some kind of trip. It looked like Himaruya was indecisive of whether he wanted Yongsoo to wear a durumagi or a jeogori, so he said "let's make the undershirt as long as a durumagi!"
For reference, left is a jeogori and pants outfit and right is a durumagi and pants outfit. These are the 2 main hanbok types for men.
I can't think of a single character whose character design was this flawed and so inaccurately done. It's like he didn't even care or put any thought into Korean traditional wear. It makes me laugh when I see how Japan is given such accurate clothing in contrast.
His clothing is a caricature of what Korean wear is. Thankfully, I don't see a lot of art of him wearing it anymore, but when it does appear it really does feel disrespectful.
His Personality
I don't really have a problem with his energetic personality, but if you know anything about his depiction in the manga, you know what I'll be talking about:
His "hobby" where he takes credit for inventions, and his weird "quirk" involving sexually harassing Japan.
What...was the reason for this exactly? A lot of personality quirks and gags of characters are rooted in some existing stereotype many people attribute to the country, like
America -> eats a lot of food, bright colored cake -> US's reputation as a country with a lot of fast food and artificially colored desserts
England -> food is inedible -> England's reputation of unappetizing foods
Korea -> claims credit for other countries' creations(Mostly Japan's), sexually harasses Japan -> ?????
This is why I don't accept some Westerners trying to brush South Korea aside "because everyone gets dunked on in Hetalia!" yes, but to what degree?
A Japanese man writing his Korean character to be stealing from the Japanese one says a lot, that Korea doesn't have a culture of its own, or most of it isn't their own. Or daresay, Korea takes Japanese culture and claims it to be their own. All three of these conclusions are problematic, and audacious coming from a person hailing from the empire that attempted to stamp our culture out and penalized those trying to preserve our culture.
The "grabbing Japan's chest" bit originates from an ongoing political dispute of an island known as Dokdo, or as Japan calls it, Takeshima. Personally, I'd agree that Dokdo belongs to Korea, referring to maps produced by Japan from the 1800s:
Yellow is marked as Korean land, with even the writing labeling it as "Joseon Land." But regardless of which side is correct, there is something about taking an ongoing territorial dispute(it was a much bigger issue while Himaruya was writing Hetalia) and applying it with the context of "haha he grabs Japan's chest."
It paints Korea as unreasonable and a sexual assaulter so that Korean grievances against Japan can be dismissed. Additionally, both countries have a rampant sexual assault issue(my phone's shutter sound cannot be turned off–a feature of phones only made in/for Korea and Japan), which is why it's also insensitive to give this trait to Korea and make light of this sensitive topic, while also...not extending this to Japan.
Let's not mention making Korea the harasser given the history and Japan's position too. Korea's red light districts and sex/entertainment industry was started by and formalized by the Japanese occupation so they could exploit Korean women.
"Korea had been a Japanese colony since 1910, and the proximity of colonial Korea to Japan, its established colonial bureaucracy and transportation network, and the presumed “cleanliness” of its young female population meant that likely the largest percentage of comfort women came from Korea. Another reason for the large numbers of Korean girls and young women in the comfort women system was the well-developed state of the Japanese colonial sex industry in Korea and its networks of human trafficking. This industry, which had been growing with Japanese encouragement since the late nineteenth century, blossomed under the Japanese colonization of Korea (1910–45) and provided networks for obtaining and trafficking sexual slaves." - Music and Dance in the Japanese Military “Comfort Women” System: A Case Study in the Performing Arts, War, and Sexual Violence by Joshua D Pilzer
Now, the "claiming everything is Korean" bit. The whole gag is Korea is delusional haha look he's claiming something Japan made as his!! While Japan is just looking at him like "ok...sure..go off whatever ig." Again, making Korea to be an unreasonable childish character while Japan is mature and just trying to get along, let bygones be bygones! Look at the sassy child I have to deal with guys!!!
Speaking of "sassy child..."
Korea's age
I haven't checked the wiki in a hot minute, but there were 2 details of his age I remember.
he's 15
he was "born" 1945(liberation of Korea from Japan) or 1948(Creation of South Korean govt)
This would be contrary to even the manga, as it references a painting by a Japanese artist in the 1700s of what he assumed were Joseon messengers stealing chickens during their mission to Japan. Korea was alive then as depicted in the picture referencing the real one, so it's safe to say his existence should predate even 1945.
(Interesting to note that Himaruya says that Koreans interpret it as Japanese bullying the Korean envoys, when Korean sources actually suggest it could be children playing around.)
Even if Korea was set to be born 1945 or 1948, it doesn't do us justice. Why do we not have a history before colonization? How is it that Korea could be even younger than America, when the Joseon Dynasty was established a century before Christopher Columbus reached America in 1492? How is it that Japan gets to be older and Korea doesn't?
It's glaringly obvious, but Korea's "childish, immature personality" stems from Japanese imperialist rhetoric of Koreans during the Colonial Era, of people needing to be civilized.
"In April 1919, Baron Goto Shinpei (Home Minister, 1916–1918) addressed a luncheon attended by US Treasurer John Burke. Goto contended that Japan did not act duplicitously in 1905, but instead, “with the full cognizance of the United States government.” "He added, “under the efficient government of Japan, the Korean people rapidly advanced in civilization and enjoyed the blessings resulting from the development of productive industry, as well as the spread of education." - The March First Movement in America: The Campaign to Win American Support by Brandon Palmer
The most important thing to remember in all of this was that during the time of Korea's controversy, Anti-Japanese sentiment was still quite high because of the unhealed wounds as a result of 35 years of Japanese Occupation. When you think about your colonizer making a personification of your country and depicting him as
-someone that copies from the colonizer and harasses them, a contrast to the "mature" colonizer
-someone with barely a history before the colonizer
-someone who's clothes are so wildly inaccurate
then wouldn't you too be enraged? This is what caused the National Assembly to ban the official airing of the anime, and official releases of the manga. You'll notice even these days Koreans are hostile towards Hetalia, even as the incident happened years ago, whereas the Countryhumans had a large Korean following and creators, because one of them was openly treating their country like a personification from a political cartoon found in a 1920s Japanese newspaper, and the other was fan created.
I hope this perspective was helpful in explaining why certain qualities of canon are disrespectful. Please remember before defending "canon" Hetalia, Hetalia is made by a Japanese author who was found to have been on Japanese right wing forums. Don't try to convince a Korean that his depiction/canon of Korea is respectful.
