MGM Osaka to feature 6,000 gaming machines, 27-storey arc-shaped tower
Summary
Newly released architectural documents give a clearer picture of MGM Osaka, Japan’s first fully authorised casino-centred integrated resort, being developed on Yumeshima Island by a consortium led by MGM Resorts International and ORIX. The project — estimated at about $10 billion — is slated to open around autumn 2030.
The resort’s main feature will be a 27-storey, 126-metre arc-shaped tower housing two hotels (around 1,840 rooms combined), the principal casino and a theatre. Plans show the casino occupying roughly 23,293 square metres with about 470 gaming tables and approximately 6,400 electronic gaming machines.
Beyond the tower, the development includes a large convention and exhibition complex (four storeys, c.27 metres high, covering roughly 16.7 hectares) to boost MICE and business tourism. A third hotel (13 above-ground floors, 56 metres, c.660 rooms) will provide studio spaces for cultural activities, bringing the resort total to about 2,500 rooms across three hotels. The full site spans close to 50 hectares near the former Osaka-Kansai Expo grounds. Groundworks began in late 2023 and construction formally broke ground in April 2024.
Key Points
- Project cost is estimated at about $10 billion and is led by an MGM–ORIX consortium (each holding roughly 40%).
- The signature structure is a 27-storey, 126-metre arc-shaped tower with two hotels (c.1,840 rooms), main casino and theatre.
- The casino floor is planned at ~23,293 sq m with ~470 gaming tables and ~6,400 electronic gaming machines; accessible to locals and international visitors under Japan’s regulatory framework.
- A major four-storey convention and exhibition complex (c.16.7 hectares) will support Osaka’s MICE ambitions, contributing to ~730,000 sq ft of MICE/tourism space overall.
- A third hotel (c.660 rooms, 13 floors) will include studio spaces for cultural activities, blending traditional Japanese experiences with hospitality.
- The entire development covers nearly 50 hectares; construction commenced following preparatory work in 2023 and a 2024 groundbreaking.
- Japan’s Integrated Resorts Act allows up to three such resorts nationally; a new application window opens 6 May–5 Nov 2027, so further bids (e.g. Hokkaido, Nagasaki) are likely.
Context and relevance
MGM Osaka is a landmark for Japan’s nascent integrated-resort sector: it is the first fully authorised casino resort under the country’s new IR legislation and signals substantial private investment into tourism, MICE and urban redevelopment in Osaka. The scale — large gaming floors, multiple hotels and a major exhibition centre — highlights how operators are positioning IRs as mixed-use economic engines rather than pure gambling venues.
For the gaming industry, this project sets a template for future Japanese IR bids and will shape supplier, operator and regulatory conversations ahead of the 2027 application window. For regional planners and tourism stakeholders, MGM Osaka underlines the push to convert former expo land into long-term economic infrastructure aimed at international business and cultural visitors.
Why should I read this?
If you follow gaming, tourism or Japanese economic policy, this is the big-ticket development everyone’s talking about. Think: $10bn, a Bellagio-style arc tower, thousands of machines and a serious push to turn Osaka into a MICE hotspot. Short version — it’s where the industry’s headed in Japan, and it matters.
