Citing two sources, the article Korea under Japanese rule gives the following figures showing that very few Koreans who volunteered for enlistment into the Japanese army 1938 – 1943 were actually accepted.

enter image description here

Although some would have failed the medical, the acceptance seems far too low for this to be the only reason. Another possible reason is that the Japanese might have been worried about loyalty of these recruits, though even before World War II there were examples of Koreans who had been promoted to officers in the Imperial Japanese Army: Hong Sa-ik - later executed by the Allies for War Crimes - is one example, while Yi Un reached the rank of Colonel in 1935 and Lieutenant General in 1940. Five others also reached the rank of General by the end of the war.

Further confusing the picture is the forum post Koreans in the Imperial Japanese service which (citing specific dates and sources) seems to contradict the information in the Wikipedia article on enlistment, stating that enlistment targets prior to 1944 were not even close to being met. Referring to 1938,

Initially, the Army Special Enlistment System targeted "those who are better-off than average and ideologically solid"...However, it turned out that these wealthier Koreans were for the most part unwilling to enlist.

The article also mentions

blackmailing new graduates, putting pressure on families by detaining the father, or tricking them into enlisting by falsely informing them that doing so was just a formality.

Further, the article quotes An Outline of the History of the Army System by Masao Yamazaki that some (It’s not clear who the ‘some’ are) also insisted:

It is not appropriate to carry out this war only at the expense of Yamato people (ethnic Japanese) because if the war kills only Yamato people yet leaves Koreans, they will, together with their formidable power to reproduce themselves, pose a serious threat in the future

Despite the apparent contradictions in these two articles, they do both show that the number of Koreans serving in the Japanese army was low, which brings us back to the main question: why was this the case? Were perhaps those Koreans applying mostly from poor families and thus not the ones the Japanese wanted?

Note: I say 'apparent contradictions' as I'm not sure if I've correctly understood some the points in the second article cited - I'm no expert in this field.

    I may have understood your "confusion" ( to me, not confusion at all ) As I commented to you at the deleted post, I may later reconstruct the new post. But I have to finish another answer first. I am sorry. And good luck.

    I do not think being poor or a simpleton was enough reason to reject a recruit. The grandfather of a friend of mine was from a Japanese rural village. When the village boys were recruited for WWII, he was selected for training as a Sargent because he was among the few that could read. It means that the bulk of privates recruited from that Japanese village could not read (I understand that reading Japanese at a proficient level requires more years of education due to the number of Kanji to memorize, so may be the privates could read simple texts but not complex ones)

    It comes from history of both countries... Koreans for Japanese were rough equivalent of Jews for Nazi Germans... There was a reason why Japanese Royal Family only relatively lately publicly admitted to Korean heritage of the lineage (in origin or something included into the bloodline along the way)...

The reason is simple: those were the allocated quotas[3].

The apparent contradiction observed in the question stems form the fact that Japan was not as politically united as is often assumed. The recruitment of "volunteers" was carried out by the colonial administration of Korea, where there was significant support for the idea.

Aside from some Koreans who thought they could leverage service into more political rights, Japanese officials in the General-Governerate, as well as officers of the Korean Army, had been enthusiastic advocates of enlisting Koreans. They conceived military service as both a demonstration of, or alternately a vehicle for, promoting Korean integration, which was incidentally also their jobs.

(What seems to be not mentioned yet is that the volunteers were sent to training centres for "re-education" into loyal imperial subjects).[2]

It's also worth noting that, even though racism was pervasive and deeply ingrained even among advocates, many Japanese thinkers and colonial officials were ideologically committed to racial equality.[1] Recruitment of Korean volunteers was thus in no small part a propaganda campaign to persuade ethnic Japanese into accept Koreans as equals.

The actual decision to accept volunteers into the Imperial Army, however, rested with the military in Tokyo, where the Special Volunteers program was conceived of merely as a trial[1]. Thus, regardless of how many "volunteers" the colonial administration was churning out to impress metropolitan Japan, the War Ministry never planned on accepting more than a handful in the first place - the quota set for the first year was 400.[3]

In any event, most recruits probably wouldn't have qualified. Besides physical requirements, the Imperial Army insisted on proficiency in the Japanese language as a measure of "recruit quality", since the Koreans were to serve in integrated units.[4] For obvious reasons, this disqualified most volunteers: the General-Govenerate of Korea estimated in 1937 that only 5.85% of young Koreans were able to converse in Japanese.

Furthermore, the recruits were also screened for ideological fitness. Many applicants were thus rejected for personal or familial sympathies towards Korean nationalism, or communism.


[1] Fujitani, T. Race for Empire: Koreans as Japanese and Japanese as Americans during WW2. UoC Press, 2011:
"[E]ven after July 1937 War Ministry officials still overwhelmingly believed that the recruitment of Koreans was premature. However, considerable effort on the parts of the Korean Army's high officers and the Government-General alleviated their fears . . . the military authorities inaugurated the new system on a trial basis, [so] the number of Korean volunteers initially accepted was very small."

    This is quite a good answer.

The book Divine Work, Japanese Colonial Cinema and Its Legacy at page 87 cites the same statics as the OP and then states:

Brandon Palmer comments that unwilling applicants were rejected in favour of those who had demonstrated clear patriotism and a real willingness to join (Palmer 2013: 70–1). There is also the factor that the army offered financial incentives and, therefore, those from the poorer end of the economic spectrum would be more likely to apply. However, as a result of their socio-economic background, they potentially suffered from ill helath, thus leading to a higher rate of rejection. Rather obviously, the later soldiers who came from conscription tended to be far less 'satisfactory' than the volunteer brothers. Often lacking Japanese language skills and in poorer physical health than the previous Korean volunteer recruits (Utsumi 2005: 85), many performed badly. Many tried to desert and those caught would usually be executed as a warning...

Palmer (at page 77 of the linked edition) has further statistics and explains that, for example in 1941, only about 50,000 of the ~145,000 applicants were true volunteers.

    +1. This seems to explain things at least in part, though I'm not sure if it covers an average 98% rejection rate for 1941-43. Was the ability to speak Japanese a strict requirement? That (plus the other reasons given) might explain why so many applicants were rejected. Jul 23, 2018 at 3:13

    @LarsBosteen it wouldn't surprise me if the Japanese didn't want Koreans (who they considered greatly inferior, not unlike the Germans and their opinion of the Slavs) into their armed forces, would rather see them as forced labour on farms where they belonged. So keeping them out of the armed forces kept them on the farms, producing food for the Japanese when they most needed it.

    @LarsBosteen Palmer says at page 70 ""Japanese language comprehension was critical...Colonial authorities believed that if a Korean did not understand Japanese, he was not qualified for military service".
