"We are going to have a larger office here in Tokyo," Chairman and Chief Executive Officer James Murren told reporters at an investor conference in Tokyo.
MGM has hired 15 new staff to work in Japan to focus on areas including market research and building connections with local companies, Murren said. Between eight and nine of the staff will be based in Tokyo.
International casino operators, including Las Vegas Sands and Melco Crown Entertainment, are also in the running for potentially lucrative operating rights in Japan, which legalised casino gambling in December.
