Japan's pachinko parlors, at their 1994 peak, generated more revenue every year than the country's entire automobile export industry — and roughly 80 percent of them are owned by ethnic Koreans, whose grandparents were brought to Japan as workers during the colonial occupation of Korea

Walk down essentially any commercial street in essentially any Japanese city on essentially any weekday evening in 2026 and you will pass at least one building emitting a distinctive electronic clatter — the specific sound of thousands of small steel balls cascading simultaneously through the vertical pin fields of arcade-style gambling machines that Japanese law classifies as “amusement devices” rather than “gambling equipment” on the specific legal technicality that the machines dispense special-prize tokens rather than cash, which the players then walk approximately 20 metres to an unmarked side-street exchange window operated by an entirely separate corporate entity that pays them cash for the tokens. This is pachinko. At its December 1994 peak, before the subsequent 30-year decline in Japanese consumer spending on the specific category, the Japanese pachinko industry generated approximately ¥30 trillion in annual revenue — approximately $300 billion at contemporary exchange rates, approximately 6 percent of Japanese GDP, and substantially larger than the entire Japanese automobile export sector (approximately ¥10-12 trillion in the same year) that essentially every Western observer at the time considered the substantive engine of the Japanese post-war economic miracle. In 2023, the pachinko industry was still generating approximately ¥15.7 trillion in annual revenue — larger than the Japanese film, music, and professional sports industries combined, and approximately ten times the annual gaming revenue of Las Vegas. And approximately 80 percent of the parlors are owned by ethnic Koreans whose grandparents did not come to Japan by choice.

The specific historical mechanism by which the substantially largest entertainment industry in modern Japanese economic history came to be dominated by an ethnic minority whose grandparents had been brought to the country under colonial conditions is one that essentially none of the Japanese consumer marketing literature about pachinko has substantially engaged with. As detailed in Stanford University’s Freeman Spogli Institute analysis of the historical position of Koreans in Japanese society, the substantive origins of the modern Japanese Korean population lie in Japan’s 35-year colonial occupation of the Korean Peninsula between August 1910 and August 1945. The Japanese colonial administration systematically dismantled Korean linguistic, religious, and cultural institutions; required Korean citizens to adopt Japanese surnames beginning in 1939; and progressively conscripted approximately 700,000 Korean workers into wartime labour mobilisation across Japanese domestic factories, mines, and construction sites between 1939 and 1945 under the 1938 National Mobilisation Law. By August 1945, approximately 2 million ethnic Koreans were residing in Japan. Following the Japanese military surrender and the subsequent liberation of Korea, approximately 1.4 million ethnic Koreans returned to the Korean peninsula. Approximately 600,000 remained in Japan — the specific population that would subsequently be known by the Japanese term zainichi (在日, “residing in Japan”), and whose descendants currently number approximately 430,000 to 450,000 permanent residents plus additional naturalised Japanese citizens.

The specific reason the Zainichi Korean community entered the pachinko industry in the specific concentration that has characterised the industry across the subsequent 78 years is that they had been formally excluded, by both statutory law and informal social practice, from essentially every other employment sector in the postwar Japanese economy. Per the J-Koreans historical archive’s specific analysis of the Zainichi Korean role in the Japanese pachinko industry, the December 1945 revocation of Zainichi voting rights was followed by the 1947 Alien Registration Law (which formally reclassified Zainichi residents as foreign aliens despite their longstanding residence in Japan), the 1950 Nationality Law (which stripped Japanese nationality from Zainichi children with Japanese mothers), and a broader pattern of systematic exclusion from public sector employment, major corporate hiring, professional licensing, university admissions, housing markets, and marriage networks that persisted essentially unchanged across the first 40 years of the postwar Japanese economy. The specific consequence of these exclusions was that Zainichi Koreans could not, in essentially any practical sense, participate in the standard salaryman career trajectories that produced the substantial majority of Japanese middle-class household income across the same period. What they could do was start small businesses in the specific commercial sectors that Japanese mainstream capital had not yet organised into corporate ownership — which, in 1947, primarily meant the informal restaurant sector (giving rise to the substantial Japanese yakiniku Korean-barbecue restaurant industry) and the newly-emerging pachinko parlor sector.

What the industry actually is

The mechanical and legal structure of the pachinko industry that the Zainichi community subsequently built across the 1947-1994 period is, by every account of contemporary Japanese entertainment industry analysis, substantially unusual. As described in Hinomaru’s cultural and economic overview of the Tokyo pachinko industry, the specific legal fiction that has allowed the industry to operate at gambling-industry scale under formal Japanese anti-gambling statutes is the “three-store system” (三店方式, santen hōshiki): the pachinko parlor itself dispenses winning players not with cash but with small “special prizes” (特殊景品, tokusu keihin) — typically gold-plated tokens or small ornamental objects with no evident consumer utility outside the specific pachinko-adjacent commercial ecosystem; the player then walks approximately 20 to 50 metres to a small unmarked exchange window on a nearby side street, operated by an entirely separate corporate entity (with no formal legal or ownership relationship to the pachinko parlor), which purchases the special prizes for cash at a fixed rate; the exchange operator then sells the accumulated special prizes back to a wholesaler; and the wholesaler sells them back to the pachinko parlor, completing the loop. The specific legal characterisation of pachinko under Japanese law is therefore not “gambling” (which is prohibited by the 1907 Criminal Code Article 185) but rather “amusement” (which is regulated under the 1948 Businesses Affecting Public Morals Regulation Law). The distinction is substantive in Japanese criminal law and substantively meaningless in essentially every other jurisdictional framework.

The North Korean question

The substantive complication that has attached to Zainichi Korean ownership of the pachinko industry across the entire post-war period is that a specific fraction of the Zainichi community — organised primarily through the North Korean-aligned Chongryon (General Association of Korean Residents in Japan, 在日本朝鮮人総聯合會, founded 1955) — has, across the subsequent 70 years, allegedly used the accumulated cash flow from Chongryon-affiliated pachinko operations to remit substantial capital to the North Korean government in Pyongyang. As detailed by Statista’s aggregation of the Japanese pachinko industry market data across the 2013-2024 period, the specific magnitude of the alleged Chongryon-to-Pyongyang remittances has been variously estimated by Japanese law enforcement and financial intelligence agencies at between several hundred million and several billion US dollars annually across the 1970s and 1980s peak of Chongryon influence, before subsequently declining across the 1990s and 2000s as Japanese anti-money-laundering regulations tightened, the North Korean economy collapsed, and the Chongryon organisation itself lost the substantial majority of its Zainichi political influence. The Mindan (Korean Residents Union in Japan, 在日本大韓民國民團, the South Korean-aligned counterpart to Chongryon, founded 1946 and currently the substantially larger of the two Zainichi political organisations) has, across the same period, involved a different fraction of the Zainichi community in the pachinko industry without the associated Pyongyang remittance controversy. The specific Zainichi Korean population that continues to own the substantial majority of the modern Japanese pachinko industry is, in essential respects, a community whose grandparents were brought to Japan by force under colonial occupation, whose parents were legally excluded from mainstream Japanese employment across the postwar reconstruction period, and whose specific commercial success across the subsequent seven decades has become substantially inseparable from both the largest single legal-gambling industry in the modern developed world and the ongoing security politics of the specific Korean geopolitical division that Japanese colonial policy substantially contributed to producing.
