Osaka City Mayor Ichiro Matsui has just teased the potential casino partners the city has lined up for a potential integrated resort (IR) bid. GGRAsia reports seven operators participated in a recent request-for-concept (RFC) process initiated by the city. Of those seven, Matsui said that five were “top” overseas firms in a May 30 media briefing.

The seven operators Matsui referenced weren’t named, but the number lines up nicely with seven operators who showed interest at the recent Japan IR Expo held in Osaka. Those companies were: Galaxy Entertainment Group Ltd, Genting Singapore Ltd, Las Vegas Sands Corp, Melco Resorts and Entertainment Ltd, MGM Resorts International, Wynn Resorts Ltd and an “Osaka local alliance.”

Matsui didn’t really have anything else to share about the RFC or the resorts interested in setting up in Osaka, but his recent election as Osaka Mayor (swapping positions with former mayor and party-mate Hirofumi Yoshimura, who is now Governor of Osaka Prefecture) continues his Osaka Restoration Party’s platform of aggressively pushing to set up an IR before 2025.

Analysts don’t believe they’ll be able to hit that target, citing a slow and conservative approach of the Japanese government in issuing the licenses. Even if licenses are given out late this year, it would be a crunch to get a $10 billion resort built by 2025, when analysts expect it would take as much as five years to construct such a resort.
