Koreans in Japan in the context of "Fukuda Village Incident"

The Kantō Massacre (關東大虐殺; Korean: 간토 대학살) was a mass murder in the Kantō region of Japan committed in the aftermath of the 1923 Great Kantō earthquake. With the explicit and implicit approval of parts of the Japanese government, the Japanese military, police, and vigilantes murdered an estimated 6,000 people: mainly ethnic Koreans, but also Chinese and misidentified Japanese, and Japanese communists, socialists, and anarchists.

The massacre began on the day of the earthquake, September 1, 1923, and continued for three weeks. A significant number of incidents occurred, including the Fukuda Village Incident.

Koreans are an East Asian ethnic group native to the Korean Peninsula. The majority of Koreans live in the two Korean sovereign states of North and South Korea, which are collectively referred to as Korea. As of 2021, an estimated 7.3 million ethnic Koreans resided outside of Korea. Koreans are also an officially recognised ethnic minority in other several Continental and East Asian countries, including China, Japan, Kazakhstan, Russia, and Uzbekistan. Outside of Continental and East Asia, sizeable Korean communities have formed in Germany, the United Kingdom, France, the United States, Canada, Australia, and New Zealand.

The General Association of Korean Residents in Japan, abbreviated as Chongryon (Korean: 총련; Hanja: 總聯; RR: Chongnyeon; MR: Ch'ongnyŏn) or Chōsen Sōren (Japanese: 朝鮮総連), is one of two main organisations for Zainichi Koreans (Korean citizens or residents of Japan), the other being Mindan. It has close ties to North Korea and functions as North Korea's de facto embassy in Japan, as there are no diplomatic relations between the two countries. The organisation is headquartered in Chiyoda, Tokyo, and there are prefectural and regional head offices and branches throughout Japan.

Mindan, officially the Korean Residents Union in Japan, contrastingly consists of Zainichi Koreans who have adopted South Korean nationality. As of 2018, among 610,000 Korean residents in Japan who have not adopted Japanese nationality, 25 percent are affiliated with the Chongryon, and 65 percent are affiliated with Mindan. As of 2016, PSIA reported that Chongryon had 70,000 members.

Korean Canadians (French: Coréo-Canadiens) are Canadian citizens of full or partial Korean ancestry. As of 2016, Korean Canadians are the 8th largest group of Asian Canadians.

Korean immigration to Canada began with seminary students in the 1940s and accelerated during the 1990s. According to the 2021 Canadian Census, there were 218,140 Korean Canadians in Canada. According to South Korea's Ministry of Foreign Affairs and Trade, there were 241,750 ethnic Koreans or people of Korean descent living in Canada as of 2019, making them the fourth-largest Korean diaspora population (behind Koreans in China, Koreans in the United States, and Koreans in Japan, and ahead of Koreans in Russia, Koreans in Uzbekistan and Koreans in Australia).
