Is Online Gambling Legal in Japan?
Japan has some of the strictest gambling laws in Asia. Under the Japanese Penal Code, most forms of gambling are prohibited, except for state-run betting like pachinko, horse racing, and lottery. However:
✅ Playing on licensed offshore online casinos is not illegal for individuals.
✅ The law focuses on prohibiting operators inside Japan, not players using international sites.
✅ Japanese players regularly access foreign casinos licensed in Curacao, Malta, or the Isle of Man.
🔒 Pro tip: Stick to secure and licensed platforms that accept JPY and offer Japanese-friendly support.
