Chōsen-seki: The Legal Status of Ethnic Koreans in Japan
Chōsen-seki (朝鮮籍), literally meaning "Korean (Joseon) domicile," is a unique legal status assigned by the Japanese government to ethnic Koreans residing in Japan. This status applies to individuals who do not hold Japanese nationality and have not registered as nationals of South Korea. While it may appear to be a nationality, it is essentially a registration category that leaves many individuals in a complex legal limbo.
The situation is further complicated by the geopolitical divide of the Korean Peninsula. Under the respective laws of North and South Korea, most people with Chōsen-seki status technically hold both nationalities. However, because they lack South Korean documentation and Japan does not recognize North Korea as a sovereign state, these individuals are often treated as stateless in practical terms.

Key Facts
- Definition: A legal status for ethnic Koreans in Japan who are neither Japanese nor registered South Korean nationals.
- Population: As of 2025, approximately 22,200 people hold Chōsen-seki status, compared to over 407,000 registered South Korean nationals.
- Legal Origin: Stemmed from the revocation of Japanese citizenship following World War II.
- Current Status: Often treated as stateless by the Japanese government due to the non-recognition of North Korea.
Historical Background
The origins of Chōsen-seki date back to the end of World War II and the subsequent surrender of Japan. During the Japanese occupation of the Korean Peninsula, ethnic Koreans held Japanese citizenship. However, this citizenship was revoked in stages as Japan relinquished sovereignty over Korea.
The Path to Statelessness
The process occurred through two primary legal mechanisms:
- The Edict of Foreigner Registration (1947): Under the Allied Occupation of Japan, this edict stipulated that Koreans were to be considered foreigners, though they technically remained Japanese citizens for a short period.
- The San Francisco Treaty (1952): This treaty formally finalized the loss of Japanese nationality for these residents.
Because the 1947 edict registered residents based on their geographical origin ("of Chōsen") rather than a specific nationality, "Chōsen-seki" became a substitute for nationality. Following the foundation of South Korea in 1948, residents could choose to register as South Korean nationals. Those who did not—whether due to an affinity for North Korea or a desire to remain politically neutral—retained the Chōsen-seki status.
Legal Treatment Across Borders
Legal Standing in Japan
Japan typically defers private civil law matters, such as family law and wills, to the home country of the foreigner. For those registered as South Korean, South Korean law applies. For Chōsen-seki individuals, Japanese courts have historically applied South Korean law, though in certain instances, they have applied North Korean law or Japanese law (the latter occurring when the individual is treated as stateless). Some individuals report facing discrimination because the status is frequently associated with North Korea.
Relations with South Korea
To obtain a South Korean passport, Chōsen-seki individuals must first register as South Korean nationals. Historically, they used special travel documents issued in Japan to visit South Korea. These practices were restricted in 2009 under the Lee Myung-bak government but were relaxed in 2017 by the Moon Jae-in government as a humanitarian gesture to normalize visits to their homeland.
The legal interpretation of this status has been contested in South Korean courts. In 2010, the Seoul High Court described a Chōsen-seki holder as a "stateless overseas compatriot." However, a 2013 Supreme Court appeal avoided the term "stateless," suggesting instead that the individual was simply not a South Korean national.
Relations with North Korea
Unlike Japan and South Korea, North Korea recognizes these individuals, issuing nationality certificates and North Korean passports for the purposes of repatriation and visitation.

Frequently Asked Questions
What is the difference between Chōsen-seki and South Korean nationality?
South Korean nationality is a recognized citizenship with a passport and diplomatic protection. Chōsen-seki is a Japanese administrative category for those who have not registered as South Korean nationals and do not hold Japanese citizenship.
Are people with Chōsen-seki status considered stateless?
Technically, they may hold nationality under North or South Korean law, but because Japan does not recognize North Korea and they lack South Korean documents, they are often treated as stateless in a practical and legal sense within Japan.
Why did some Koreans choose Chōsen-seki over South Korean nationality?
Some individuals chose to retain Chōsen-seki due to political affinities with North Korea or a personal preference not to align themselves with either the North or South Korean governments.
Can Chōsen-seki holders visit South Korea?
Yes, although the ease of travel has fluctuated. While restrictions were tightened in 2009, the Moon Jae-in government relaxed these rules in 2017 to allow more humanitarian visits to their ancestral homeland.
How did the San Francisco Treaty affect this status?
The 1952 San Francisco Treaty formally revoked the Japanese nationality of ethnic Koreans living in Japan, cementing their status as foreigners and leading to the formalization of the Chōsen-seki registration.
