The company specializes in construction and facilities modification services supporting U.S. military installations throughout the Okinawa region. As a key contractor for the Department of Defense, Ohna Denken Co., Ltd. provides design-bid-build construction services, infrastructure improvements, and specialized facility upgrades that enhance operational readiness at Marine Corps and Navy bases in Japan.
Since 2024, Ohna Denken Co., Ltd. has received five delivery order awards totaling approximately $5.22 million in ceiling value under the Camp Butler and Commander Fleet Activities Okinawa (CFAO) Marine Corps Base Design-Bid-Build Multiple Award Construction Contract (MACC) framework.

All delivery orders were awarded without socioeconomic set-asides, reflecting the contractor's competitive standing in open contracting competitions.

This contract vehicle (N40084-24-D-0071) authorizes the company to perform small magnitude design-bid-build construction requirements for Marine Corps Base Camp Butler and Commander Fleet Activities Okinawa upon receipt of task orders.
