Yokohama's Anti-Casino Mayor Has Resigned, and Japan Wants More IR Bids

Takeharu Yamanaka won in 2021 on a platform of killing the city's integrated resort bid, and did. He has now stepped down over a workplace harassment finding, weeks before a special election, in a country whose prime minister supports a second round of casino licensing and whose tourism agency will take applications from May 2027.

• Yokohama mayor Takeharu Yamanaka has resigned after an investigation found he repeatedly engaged in workplace harassment, stepping down once the city council unanimously backed a motion calling for it
• He first won office in 2021 on an anti-integrated-resort platform, which effectively ended Yokohama's bid for a casino licence, and was re-elected in August 2025
• A special election will be held on 18 October 2026, with attorney Atsumi Harasawa among the favourites and expected to have Liberal Democratic Party backing
• Prime Minister Sanae Takaichi supports a second round of IR licensing, and Japan's Tourism Agency has said it will accept further applications from May 2027
• Yokohama was once regarded as the most promising of the cities competing for one of three national licences, with Genting Singapore and Melco among those pursuing it before Yamanaka took office

The Mayor Who Ended the Bid Has Gone, for Unrelated Reasons

Takeharu Yamanaka has resigned as mayor of Yokohama following a third-party investigation that concluded he had repeatedly engaged in workplace harassment. He stepped down this week after the city council unanimously approved a motion calling for his resignation at a plenary session, according to the Mainichi Shimbun.

The investigation began after a whistleblower, later identified as a senior city human resources official, reported that Yamanaka had subjected him to coercive behaviour. The law firm conducting the review published its findings in July, finding that the mayor routinely bullied and intimidated subordinates, at times referring to them as "morons" and "human scum". Yamanaka accepted the findings and told reporters he "deeply regrets and apologizes" for his "poor choice of words".

A former Yokohama City University professor, Yamanaka first won office in 2021 on an explicitly anti-integrated-resort platform, and his election effectively ended the city's pursuit of a casino licence. He was re-elected in August 2025, and his second term has not lasted long.

Yokohama will elect a new mayor in a special election on 18 October. Attorney Atsumi Harasawa is among the favourites and is expected to be backed by the Liberal Democratic Party, which is led by Prime Minister Sanae Takaichi. Harasawa has not publicly stated a position on casino development.

The national backdrop has moved considerably since 2021. The LDP established Japan's integrated resort framework in 2018 under then-prime minister Shinzo Abe, and Takaichi has expressed support for a second round of IR licensing as a way to boost international tourism. The Tourism Agency has told local governments it is ready to accept further applications from May 2027.

Yokohama was once regarded as the most promising of the cities competing for one of three licences available nationally. Las Vegas Sands eventually abandoned its Japanese plans, but Genting Singapore and Melco Resorts and Entertainment were among those pursuing Yokohama aggressively before Yamanaka took office. Osaka remains the other focus, with MGM Resorts International executives suggesting the casino being built there could rival the Las Vegas Sands-operated Marina Bay Sands in Singapore.

A Harassment Finding Is Not a Referendum on Casinos

It is worth stating plainly, because the temptation will be to read this as the anti-IR position losing. It did not. Yamanaka resigned over conduct towards staff, after an investigation that had nothing to do with gambling policy, and his 2025 re-election suggests the platform he won on retained support. What has changed is the occupancy of the office, not the argument. Anyone briefing that Yokohama has reversed course is getting ahead of an election that has not happened.

The Timing Is What Makes This Material

Three things now coincide: a vacant mayoralty in the country's second city, a prime minister who wants a second licensing round, and a Tourism Agency window opening in May 2027. A new mayor elected on 18 October would have roughly eighteen months to decide whether Yokohama re-enters before applications open. That is tight for a process that requires an implementation plan, a partner operator and local assembly approval, which means any candidate intending to revive the bid has to say so during the campaign rather than after it. Watch what Harasawa says between now and 18 October, not what happens afterwards.

Operators Have Been Burned Here Before, and Will Move Slowly

Genting Singapore and Melco spent real money pursuing Yokohama and watched a single mayoral election extinguish it. Las Vegas Sands left Japan altogether. The lesson operators took was that Japanese IR risk is local political risk rather than national policy risk, and nothing about this week changes that: the same office that killed the bid could kill it again in four years. Expect interest to be expressed carefully and capital to be committed late, with more weight given to whether a city's assembly and business community are behind a bid than to what any individual mayor says.

Japan's second licensing round now has a plausible third candidate city. It also has a reminder of why the first round produced only one approved bid.
