MGM Osaka Casino Resort to Transform Yumeshima Island 2030

After the six-month World Expo 2025 Osaka-Kansai wrapped up on October 13, city and prefectural authorities in Osaka have shifted their focus to transforming Yumeshima Island. The former Expo venue is set to become a global tourism hotspot, with plans centered around Japan’s first integrated casino resort MGM Osaka.

Phased Redevelopment Plan

The post-Expo strategy involves a three-stage redevelopment of the artificial island located in Konohana Ward. The first stage prioritizes the construction of MGM Osaka, a collaboration between MGM Resorts International and Orix Corporation, which is already underway on the northern edge of the site.

Later stages will turn the remaining Expo grounds into a multifunctional district with leisure, commercial and entertainment facilities. Proposals include a 50-hectare zone featuring a race track, water park, hotels and a flexible-use arena to complement the resort once it debuts in 2030.

One of the Expo’s signature features, a 200-meter stretch of the Grand Ring wooden overpass will be preserved and reconstructed as the centerpiece of a new 3.3-hectare public park. The project is estimated to cost JPY9 billion (about USD 59.5 million), potentially financed from Expo surplus funds.

Osaka officials intend to open development bids to private firms by spring 2026. While detailed timelines for phases two and three are still under review, the overarching goal is to create synergy between the integrated resort and surrounding attractions to strengthen the city’s global tourism profile.

MGM Osaka: A Landmark Casino Resort

Occupying 49 hectares next to the Expo grounds, MGM Osaka broke ground in April 2025. Backed by an initial investment of JPY1.27 trillion (around USD 8.9 billion), the total cost could reach JPY1.5 trillion (USD 10.2 billion) with inflation and construction adjustments.

The resort is slated to open in autumn 2030, welcoming approximately 20 million visitors annually. Alongside gaming areas, it will include hotels, convention halls, and entertainment spaces, all operating under Japan’s casino regulations.

Long-Term Economic Vision

Analyst Hideyuki Araki of Resona Research Institute notes that this redevelopment is part of a broader, long-term growth strategy for Osaka. Combining the Expo legacy with the casino resort is expected to fuel the Kansai region’s tourism and economic development for decades.

Authorities are also implementing strong counter-measures to address gambling addiction, including a specialized support organization offering prevention, consultation and treatment services.

Building Osaka’s Tourism Future

As the Expo era closes, Osaka is positioning itself as a top Asian destination. The transformation of Yumeshima Island into a comprehensive leisure and entertainment hub anchored by MGM Osaka and complemented by parks, commercial spaces and attractions reflects a vision that extends well beyond gaming.

By blending preserved Expo heritage with cutting-edge development, Osaka aims to build a sustainable, innovation-driven tourism model capable of boosting the region’s economy for years to come.
