MGM Osaka Unveils Casino & Resort Architecture Plans

New architectural plans have provided the clearest picture yet of MGM Osaka, Japan’s upcoming first integrated resort. The JPY1.51 trillion (US$9.63 billion) development will feature a 23,293-square-meter casino floor, housing roughly 470 tables and 6,400 slot machines, according to city government documents recently shared with the media.

Major Collaboration in Osaka
The project represents a landmark partnership between Osaka city and prefectural authorities, U.S.-based MGM Resorts International, Japan’s Orix Corp, and other local investors. Slated to open in late 2030, MGM Osaka aims to transform the region’s tourism scene with a fully integrated resort combining entertainment, hospitality and business facilities.

Design Inspired by Las Vegas
The main tower, rising 126 meters across 27 floors with an additional basement level, is reportedly inspired by MGM’s Bellagio in Las Vegas. It will host two hotels totaling 1,840 rooms and anchor the resort’s casino and entertainment offerings, combining modern luxury with elements of Japanese culture.

Complementary Facilities
A second hotel building will offer 660 rooms over 13 floors plus a basement, featuring spaces for cultural experiences like traditional tea ceremonies. The resort will also include a MICE (meetings, incentives, conferences, exhibitions) center covering four above-ground floors and a basement, with two large halls and multiple meeting rooms. The entire complex spans 16.7 hectares and includes a multi-storey parking structure for guests.

A Milestone in Japan’s Gaming Industry
These architectural disclosures confirm that MGM Osaka is moving beyond planning into full-scale development. With its detailed hotel capacities, casino floor size and MICE facilities now clear, the resort is shaping up to be a flagship integrated destination ahead of its 2030 opening.
