Kanto Ryokuka Co., LTD.

Kanto Ryokuka Co., LTD., a for-profit Japanese company headquartered in Tokyo, holds a single-award indefinite-delivery/indefinite-quantity contract with the U.S. Air Force's Pacific Air Forces for vegetation management, tree trimming, and tree removal services at Yokota Air Base and geographically separated U.S. Air Force units throughout Japan, performing work directly with no identified subcontractors.

Kanto Ryokuka operates exclusively as a prime contractor on full-and-open federal awards with no set-aside designations. The vendor's capability portfolio centers on landscaping services and forestry support, delivered in-country at military installations in Japan. Primary work includes tree trimming, tree removal, vegetation management, and grounds maintenance in compliance with local Japanese environmental standards and commercial practices. Representative delivery orders include a $4.425 million firm-fixed-price order for tree trimming and removal at the Old Paint Ball Area in Tama (January 2022), a $23.075 million order for tree trimming and removal at Tama Fence Phase 5 (December 2021), and a $243,356.33 order for comprehensive tree management across Yokota Air Base and geographically separated units (July 2024).

Customer concentration is extreme and single-threaded. Pacific Air Forces accounts for 64 of 68 total awards (94%) and $44.9 million of the $48.5 million combined potential value. The vendor has minimal exposure to other federal customers — three awards totaling $87 thousand to the Department of the Air Force and one $3.5 million award to Defense Media Activity.

The vendor's vehicle position rests on two PACAF IDIQs. The primary vehicle is Indefinite Delivery Contract FA520923D0008, a $4.8 million single-award IDIQ awarded September 11, 2023, with a performance period extending through September 2033, which anchors 20 task orders valued at $5.8 million combined. The second vehicle is Indefinite Delivery Contract FA520918D0006, which carries 40 task orders totaling $33.7 million in combined potential value. Both vehicles support tree trimming, removal, and vegetation management at Yokota Air Base and subordinate Air Force units across Japan.

Activity has declined year over year — nine awards in 2022, ten in 2023, eight in 2024, six in 2025, and three through March 2026 — signaling a slowing award cadence. No recompete cliff data is provided in the source. The vendor has been registered in the federal System for Award Management since 2004 and has maintained a continuous contracting footprint with Pacific Air Forces across the recent award span.

The vendor's footprint is heavily concentrated in NAICS 541620 (Landscaping Services, 65 awards) and PSC code D301 (Housekeeping–Landscaping/Groundskeeping, 55 awards), with secondary work in forestry support activities and tree-thinning services. Obligated dollars total $5.5 million against a potential ceiling of $48.5 million, reflecting the indefinite-quantity nature of the IDIQs and variable task-order placement. Place of performance is entirely Japan, with administrative and operational control centered on Yokota Air Base and Tama Service Annex in Tokyo.
