## Questions

### Who owns Diamond Realty Management and how does the ownership structure affect governance?

Diamond Realty Management is a consolidated subsidiary of Mitsubishi Corporation, which established the platform in 2007 with co-sponsor Mizuho Bank. Mitsubishi Corporation provides strategic oversight and long-term capital commitment, which allows the real estate team to operate with a patient, institutional investment horizon. This corporate backing means the firm does not face the same redemption pressures or fundraising cycles as independent managers, but it also operates within the governance framework of a publicly listed Japanese trading company.

### What is Diamond Realty Management's geographic footprint?

The firm executes across three primary regions: Japan, the United States, and Southeast Asia. In Japan, the portfolio concentrates on major metropolitan markets — Tokyo, Osaka, and Nagoya. US investments have focused on multifamily and industrial properties in gateway and secondary cities. Southeast Asian exposure has historically included Vietnam and other emerging markets where Mitsubishi Corporation maintains a significant operating presence.
