How to play Colors
The regulatory framework strictly keeps the casino component in check. Casino floor space is capped at 3% of the total floor area of the IR, while Japanese residents are restricted to three visits per week and 10 visits within any 28-day period. Each visit also carries a mandatory ¥6,000 entry fee, reinforcing the government’s intent to curb excessive gambling even as it opens the door to casinos.
Japan’s path to IR legalisation was not straight forward. The IR Promotion Act, which set Japan on the road to casino-integrated resorts, was passed in December 2016 after a contentious debate. Nearly two years later came the IR Implementation Act, which laid out the regulatory frameworks for casinos, from entry restrictions to measures addressing gambling addiction and other social concerns. Yet even as the government pitched IRs as a catalyst for tourism, regional development and economic growth, opposition remained aggressive.
Among the opposing forces was Kenji Eda, a prominent House of Representatives lawmaker from Yokohama and a senior figure in the opposition Constitutional Democratic Party of Japan. Eda has been a vocal critic of the government’s IR push, raising concerns over gambling addiction, the economic impact on local businesses and whether the casino-led model would deliver the promised benefits.

A hearing before the Supreme Court would be the culmination of what has been the biggest sports betting-related development since PASPA. Perhaps no other issue has united gaming stakeholders from various companies, tribes, states and regulators.
Beginning with the US presidential elections in November 2024, when prediction markets catapulted into mainstream culture, their rise has been undeniable. Kalshi and Polymarket have seen their valuations balloon to $40 billion and $21 billion, respectively, and the majority of the top US bookmakers have scrambled to expand into the prediction space in various forms, either by building their own exchanges, acquiring existing ones or engaging in market-making.
Commercial sports betting generated just under $17 billion in nationwide revenue in 2025, which is why Davenport asserts that the “stakes of this case are exceptionally high”. Kalshi and Polymarket alone posted more than $45 billion in trading volume, which is similar but not identical to betting revenue, in August. That was a 15% decline from July, although that drop is attributed to the conclusion of the Fifa World Cup tournament that month per Yahoo! Finance.
