Yokohama Casino Ban Pledge Puts Japan IR Policy Back In Focus
Yokohama’s casino policy is back in the political spotlight ahead of the city’s upcoming mayoral election, with independent candidate Kazuma Nakatani pledging to keep casino development out of Japan’s second-largest city.
Nakatani, a former member of Japan’s House of Representatives, announced his candidacy on September 12 and has said he would seek to establish a local ordinance prohibiting casino development if elected. The proposal would require discussions with the Yokohama City Assembly before being pursued during his term.
The pledge would give Yokohama’s existing opposition to an integrated resort (IR) a potentially more formal legal and political footing.
Yokohama casino policy returns to the mayoral race
Nakatani’s position is significant because Yokohama has already abandoned its previous bid to host one of Japan’s casino-integrated resorts.
According to reporting by AGBrief, Nakatani wants the proposed ordinance to prevent casino-development procedures from progressing without residents being made aware of them. Local broadcaster TVK has also reported that the candidate intends to maintain Yokohama’s policy of not pursuing casino development.
The issue has a long political history in the city.
Yokohama had previously pursued an IR centred on the Yamashita Pier waterfront area. The project attracted international casino operators, including Genting Singapore and Melco Resorts & Entertainment, before the city abandoned its bid following the 2021 mayoral election. Contemporary reporting described the election as a decisive test for the city's casino plans.
The city subsequently halted its operator-selection process, while Genting Singapore and Melco withdrew from their respective Yokohama plans.
Nakatani's proposal therefore represents less a revival of the abandoned IR project than an attempt to make its reversal more difficult for a future administration.
Nakatani seeks to formalise casino-free policy
The distinction is important for Japan’s gaming industry.
Yokohama’s current position against casino development has been shaped largely by political decisions. A municipal ordinance specifically designed to prohibit casino development could establish an additional institutional barrier to any future attempt to reopen the issue.
Nakatani has said he would consult the city assembly on such an ordinance and seek its passage during his term. His campaign is also positioning itself around broader governance issues, including measures aimed at eliminating harassment.
The Constitutional Democratic Party’s Kanagawa chapter decided on September 14 to support Nakatani’s independent candidacy, adding political weight to his campaign.
However, the election outcome remains unresolved, and Nakatani is only one candidate in a developing mayoral contest. His casino pledge should therefore be viewed as a campaign commitment rather than an indication that a new casino prohibition has already been enacted.
October election could clarify Yokohama’s direction
The mayoral election follows the resignation of Takeharu Yamanaka, who stepped down after controversy surrounding his treatment of city employees and acknowledged that his conduct had damaged public trust.
Official campaigning is scheduled to begin on October 4, with voting set for October 18.
For the casino sector, the election provides another indication of how local political sentiment could influence Japan’s IR landscape.
Yokohama was once regarded as one of the major potential locations for Japan’s first wave of casino resorts. Its withdrawal demonstrated the extent to which local political support could determine whether a major IR proposal proceeds.
The city's experience also contrasts with Osaka, which has continued advancing its integrated resort plans. The difference illustrates how Japan’s casino market remains dependent not only on national policy but also on local political decisions.
What the Yokohama pledge means for Japan’s casino market
Nakatani’s proposal does not directly alter Japan’s national IR framework. Instead, its immediate significance lies at the municipal level.
If enacted, a local casino prohibition could make any future attempt to re-enter the IR process considerably more politically complicated. For operators and investors, it would reinforce the importance of monitoring municipal elections and local government policy alongside national casino regulation.
The issue is particularly relevant because Yokohama had previously attracted major international operators. The city’s decision to withdraw from the IR race in 2021 effectively removed one of Japan’s most prominent potential casino destinations from consideration.
The October election could now determine whether that position remains primarily a policy choice or becomes embedded in local legislation.
For the moment, Nakatani is the clearest candidate on the issue, pledging to keep Yokohama casino-free if elected. The next stage will be whether voters endorse that position and whether a future city assembly would support the proposed ordinance.
