The MGM Osaka Integrated Resort is a landmark US$10 billion hospitality and entertainment complex being developed in Osaka, Japan. Located on the artificial island of Yumeshima, this massive project—unfolding alongside other major developments such as IHG breaking ground on a massive triple-branded hotel complex near Universal Studios Japan—is a joint venture between MGM Resorts International and ORIX Corporation. Set to become Japan’s first legal casino, the development will feature three luxury hotels comprising 2,500 rooms, a 3,500-seat theater, and extensive convention space.
The project’s budget has surged from an initial $8.9 billion to over $10 billion, driven by soaring global construction material costs and Japan’s acute labor shortages. Additionally, complex groundworks on the reclaimed island—specifically essential soil stabilization to prevent liquefaction—have significantly added to the expense. While construction officially began in April 2025, heavy structural work is temporarily restricted to minimize disruption to the adjacent World Expo 2025, further pressuring the timeline toward its Autumn 2030 opening.
