Zainichi Koreans: A complex history of migration, division, and cultural evolution in Japan

Countries & Cities · Published 29 September 2026 Swipe more like this →

In short: Zainichi Koreans are ethnic Koreans who settled in Japan during the era of Japanese rule. Distinct from later migrants, this community has navigated decades of political division, statelessness, and shifting national identities, while recently finding a new, more integrated place in Japanese society through the global popularity of Korean culture.

The term Zainichi refers to long-term Korean residents who trace their roots to the period of Japanese colonial rule. Following the 1910 annexation of Korea, all Koreans became Japanese citizens by law. However, after Japan's defeat in World War II and the 1952 San Francisco Peace Treaty, these residents lost their Japanese nationality. This left them in a precarious legal position, eventually leading to a split within the community based on the division of the Korean Peninsula.

This political fracture manifested in two major organizations: the pro-South Korean Mindan and the pro-North Korean Chongryon. For years, Chongryon held significant influence, even operating its own school system. However, as economic and political conditions diverged between the two Koreas, Mindan became the dominant faction, with approximately 65% of Zainichi now affiliated with it. Meanwhile, many families have moved away from ethnic education, opting instead to enroll their children in mainstream Japanese schools.

The community has also been shaped by waves of repatriation and migration. Between 1959 and 1984, over 93,000 people migrated from Japan to North Korea under a repatriation program, a movement that has since been documented in films like Dear Pyongyang. Conversely, the 1980s saw a new wave of migration from South Korea, distinct from the Zainichi population. Today, the perception of Koreans in Japan is shifting, largely driven by the Hallyu cultural wave, which has fostered greater mainstream appreciation for Korean music, film, and cuisine.

Despite historical tensions and discrimination, the relationship between the two nations remains deeply intertwined. Japan's current labor shortages have created new opportunities for Korean nationals in sectors like technology and healthcare. While the Zainichi population has declined over time due to assimilation and death, the community remains a vital, albeit complex, part of Japan's social fabric, reflecting a long history of movement between the two neighboring nations.
