In a high-profile crackdown on illegal online gambling, the Tokyo Metropolitan Police Department has referred popular comedians Asahi (斎藤旭, 36) and Hiroshi Sano (佐野寛, 29) of the comedy duo Butter Young to prosecutors for allegedly gambling on unauthorized overseas casino platforms.
According to police officials, the two entertainers accessed illegal online casinos via their smartphones while in Japan—an act that violates the country’s strict anti-gambling laws. Although the platforms themselves operate outside Japan, using them domestically is considered “simple gambling”(単純賭博), a punishable offense under the Japanese Penal Code.
The investigation began earlier this year after Titan, the talent agency representing the comedians, voluntarily reported the incident to authorities. An internal review revealed that several of its talents had been engaging in online casino gambling, prompting the company to notify Tokyo police.
Both Asahi and Sano reportedly admitted to the allegations during questioning. They were formally referred for prosecution—a process known in Japan as shorui sōken—with the police recommending charges.
The news has sparked widespread reaction in the entertainment world. Butter Young, known for their appearances on variety shows and comedy specials, had been gaining popularity with a growing fan base across the country.
Titan issued a public apology on July 8, stating:
“We deeply regret the incident and sincerely apologize to fans and all parties involved. We take this matter seriously and will be reinforcing compliance training within our company.”
The case has renewed public attention on Japan’s stringent stance on gambling. While certain forms—such as horse racing, boat racing, and government lotteries—are legal, participation in overseas online casinos remains prohibited, even if the platforms are based outside Japan.
Authorities have intensified efforts in recent years to monitor and deter online gambling activity, especially as access to offshore sites becomes easier through mobile apps and VPNs. The Tokyo Metropolitan Police have been particularly proactive in pursuing cases involving public figures, influencers, and online promoters.
Legal experts note that while enforcement against private individuals is relatively rare, public figures are often held to higher standards and used as examples in broader crackdowns.
Prosecutors will now decide whether to formally charge Asahi and Sano. If indicted, they could face fines or short-term imprisonment, though first-time offenders are often given suspended sentences.
Their future in the entertainment industry remains uncertain, as sponsors, broadcasters, and production companies move quickly to distance themselves from scandals involving gambling or legal violations.
