Sōshi-kaimei

Sōshi-kaimei is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sōshi-kaimei rather than just read about it. In short: Sōshi-kaimei (Japanese: 創氏改名; Korean: 일본식 성명 강요, 창씨개명) was a policy of pressuring Koreans under Japanese rule to adopt Japanese names and identify as such. The primary reason for the policy was to forcibly assimilate Koreans, as was done with the Ainu and the Ryukyuans.

Key takeaways

  • Sōshi-kaimei belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sōshi-kaimei to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sōshi-kaimei from memory before moving on to harder problems.

Reference excerpt

Sōshi-kaimei (Japanese: 創氏改名; Korean: 일본식 성명 강요, 창씨개명) was a policy of pressuring Koreans under Japanese rule to adopt Japanese names and identify as such. The primary reason for the policy was to forcibly assimilate Koreans, as was done with the Ainu and the Ryukyuans. The sōshi-kaimei has been deemed by historians as one of the many aspects of cultural genocide that the Japanese attempted to impose on their non-Japanese territories. It consisted of two parts. The first was the 1939 Ordinance No. 19, which required sōshi, literally "creation of a family name" (氏, shi); see bon-gwan. The second was the 1940 Ordinance No. 20, which permitted kaimei (change of one's given name). These ordinances, issued by Governor-General Jirō Minami, effectively reversed an earlier government order which forbade Koreans to take up Japanese names.

Order No. 124 In 1909, the Korean Empire established a civil registration law, starting the creation of a modern family registry system. With regard to the recording of details about women such as the father's surname, age, and connection to the registry holder, due to attention that needed to be given to avoiding conflict with Korean customs, the drafting of the law was not completed until April 1910, just before the annexation of Korea. By that time, a portion of Koreans had already registered Japanese-style names and the like, which generated confusion. As a result, on the basis of memoranda such as Order No. 124, "Document regarding name changes by Koreans" issued by the Governor-General of Korea on November 11, 1911, the use by Koreans of "names which might be mistaken for those of native Japanese" was no longer permitted, and strict controls were placed on the registration of Japanese-style names for newborn children. Additionally, Koreans who had registered Japanese-style names there were required to revert to their original names.

Ordinances No. 19 and 20 In 1939 and 1940, a new name-change policy came into effect by means of Ordinances No. 19 and 20. Originally, as in Taiwan, the new name-change policy was intended simply to allow change of surname (sei/seong) and given name, but because Korea had a long-established custom (recently abandoned) whereby people of the same bon-gwan (surname and clan) were not allowed to marry each other, in order that this custom could continue, it was decided that the policy would be implemented by leaving the clan name and sei the same in the family register while permitting a new family name (shi/ssi) to be registered. On the other hand, in Taiwan, which was also under Japanese rule in the same period, but did not have an analogous custom, the policy was not described as the "creation of a shi", but was simply "change of sei and na (family and given names)" (改姓名). With regard to the creation of a family name (shi), there were both "shi created by (individual) selection" (設定創氏) and "shi created by law" (法定創氏). In the half-year between February 11 and August 10, 1940, those who provided notification could create a shi of their own choosing, while those who did not provide any notification would have their shi defined by the clan name (sei) of the head of the household. After the "creation of a family name", a Korean had three names which are a family name shi, a clan name sei, and a personal name mei (first name), all of which are recorded in a person's family register along with the origin place of the clan, bon-gwan. Since all members of a family share the same family name shi, the wife's shi, and hence the first character in her legal name, would be the same as her husband's, which differed from the traditional Korean clan name sei, whereby a wife kept her original sei even after marriage (see table). Besides that, selection of a shi with a Japanese-style reading could also be approved; to go along with such a shi, it was also permissible to change one's given name to a Japanese-style name; as the change of given name was voluntary, a fee would be charged for it. Additionally, at the same time, the mukoyōshi system, i.e. an adoption of a daughter's husband (婿養子制度), which up until then had been forbidden under Korean law, was also introduced. This case was also included in the sōshi-kaimei policy. Declaration of individually selected shi and changes of given name initially (in February 1940) were conducted on the basis of voluntary notification. However, at the April prefectural governors' meeting, because of instructions such as "Special consideration should be taken so that the shi registration of all households can be completed by the coming July 20" the administration began to seriously promote the policy, and as a result, starting from April, the number of households registering individually selected shi began to rise sharply. As of April, only 3.9% of all households had provided notification for the creation of a shi, but by August 10, that figure had risen to 80.3%. Also, statements opposing the policy of sōshi-kaimei were censored according to the internal security laws. There are several viewpoints regarding this sudden increase. Most argue that official compulsion and harassment existed against individuals who would not create a new Japanese-style shi, but disagree whether this was the result of individual unauthorized practices by low-level officials , the policy of some regional government organizations, or an overall intention of the colonial government. Others argue that Koreans seeking to avoid discrimination by the Japanese voluntarily created Japanese-style family names. Regardless, of Koreans living in Korea, the proportion of those who changed their given name reached only 9.6%. Among Koreans living in mainland of Japan, the proportion of those who created a new shi by individual selection reached 14.2%.

Disadvantages if refused/opted out Refusal to comply with, rejecting, or opting out of sōshi-kaimei typically came with negative consequences. Such consequences included the following:

Worked examples

Example 1 — a first encounter with Sōshi-kaimei

Start with the simplest possible case. Write down what Sōshi-kaimei claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sōshi-kaimei before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sōshi-kaimei ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sōshi-kaimei

In research
Sōshi-kaimei appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sōshi-kaimei in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sōshi-kaimei is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1939 in Korea, 1939 in law, Anti-Korean sentiment in Japan, so understanding it makes those chapters shorter.
In everyday life
Look for Sōshi-kaimei outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
