About Izumi Support Corporation
Izumi Support Corporation Sasebo Office Division, a Japanese subsidiary of Sumitomo Heavy Industries, Ltd., operates as a prime contractor providing facilities system maintenance and repair services at U.S. military installations throughout Japan, competing under full and open competition with no set-aside designation. The vendor is 100% prime-focused across 78 awards with no subcontract footprint, holding a current $22.8 million single-award indefinite delivery contract with Navy Installations Command running through July 31, 2030, plus a portfolio of completed and active predecessor IDCs spanning from 2012 to present.
Izumi's customer concentration is extreme and immobile: the Department of the Navy Installations Command anchors 61 of 78 awards (99% coverage by award count) and $71.1 million of the combined $76.9 million potential value across the portfolio. The remaining five customer agencies—Navy Naval Facilities Engineering Command (8 awards, $1.9 million), Department of Defense Education Activity (4 awards, $1.7 million), Navy Bureau of Medicine and Surgery (1 award, $1.5 million), and Defense Commissary Agency (3 awards, $711 thousand)—are all secondary Navy or DoD operations in the Japan region and account for the residual $5.7 million. This concentration reflects Izumi's geographic specialization: work is performed exclusively in Japan, supporting Commander Fleet Activities Sasebo and subordinate U.S. military installations.
Capability framing is narrow and concrete: preventative and corrective maintenance of mechanical systems, electrical infrastructure, HVAC equipment, and real property assets at military installations. Representative delivery orders from the current IDC (awarded July 17, 2025) include a $23.9 thousand elevator-repair order (March 13, 2026) for Buildings 16 and 100, a $1.87 million recurring facilities-system-maintenance order (August 1, 2025) through July 2026, and a $14.4 thousand automatic-door-replacement order (September 15, 2025) at Building 1455. Under the predecessor IDC, Izumi delivered $1.7 million to the Department of Defense Education Activity for facilities maintenance at military-connected educational facilities in Japan (June 2022–July 2023). Across all work, PSC coding is dominated by Housekeeping–Facilities Operations Support (48 awards) and Maintenance/Repair/Rebuild of Equipment–Miscellaneous (20 awards), with NAICS 561210 (Facilities Support Services) accounting for 76 of 78 awards.
The parent IDC portfolio historically includes N4008420D6302 (20 task orders, $7.3 million), N4008415D6001 (17 task orders, $4 million), and N4008412D6301 (12 task orders, $4 million)—all now inactive or expired. Activity is flat to declining: the vendor has averaged four to five awards per year over the last five years, with only one award in 2026 to date. Only three awards complete in the next twenty-four months with combined potential value of $1.9 million, representing minimal recompete exposure in the near term. Obligated dollars stand at $21.7 million (28% of combined potential value), indicating substantial unexercised optionality within the current contract vehicle.
