Japan isn’t just one of the world’s largest economies – it’s a main hub for one of the most passionate, tech-savvy gaming audiences. With the population of around 123 million and some of the highest internet penetration and disposable income rates in Asia, Japan represents a major opportunity for online casino operators.
Despite Japan’s traditionally strict regulations, interest in online gambling is growing faster than ever. With the right strategy, the operators have a unique chance to build a loyal audience, drive impressive revenue and secure a long-lasting reputation in Asia’s increasingly dynamic market.
Overview of Japan's Gambling Industry
Japan boasts one of the world’s most robust economies, and people’s enthusiasm for games of chance continues to draw operator’s attention. According to the latest reports of IMARC Group, Japan’s online gambling market was valued at USD 8.1 billion in 2024 is projected to reach around 12.9 billion by 2033, growing at a steady CAGR of 5.3%.
One symbol for Japan’s love for gambling is the iconic Pachinko machine – a hybrid between pinball and slot games. In spite of the legal restrictions, the Pachinko industry still generates over USD 200 billion annually. Players typically win prizes like snacks or cigarettes, which can then be exchanged for cash trough nearby kiosks, allowing industry to operate legally in gray area.
Legal Framework and Licensing
The Japanese government’s approach to gambling has been gradually evolving. A major turning point arrived with 2016 integrated resort (IR) promotional bill, which paved the way for land based casinos aimed at boosting tourism and the economy. After pandemic-related delays Japan’s first integrated casino in Osaka is now officially construction, with the grand opening expected by 2030.
However, as of 2025, operating an online casino inside Japan remains illegal. That said, enforcement relatively relaxed, and millions of Japanese players still continue to access offshore online casinos.
For aspiring operators, this presents a unique opportunity: by stepping up offshore, they can still legally target the Japanese market – provided they offer strong localization, payment flexibility, and excellent player support.
