What Japan Post Maintenance Co. does

Japan Post Maintenance Co., Ltd. (日本郵便メンテナンス株式会社) is a wholly-owned subsidiary of Japan Post Co., Ltd. that provides vehicle maintenance, conveyance equipment maintenance, vehicle fleet management, and postal supply/advertising media products to support Japan's postal and logistics infrastructure. Founded in its current form through a 2016 three-way merger of three Japan Post Group subsidiaries (predecessors dating to 1967, 1972, and 1991), the company operates from its Tokyo headquarters in Koto-ku with 336 regular employees as of April 1, 2025, and runs 15 vehicle maintenance branches (11 designated factories, 4 certified factories) and 4 conveyance equipment maintenance centers co-located inside Japan Post facilities across all major Japanese regions.

Its service portfolio spans four lines: (1) vehicle maintenance including periodic inspections (shaken), repairs, and pallet/container repair for postal transport; (2) vehicle management services coordinating over 100,000 postal delivery motorcycles through a nationwide network of approximately 5,000 partner maintenance shops; (3) conveyance equipment maintenance for sorting and conveyor systems at post offices and private logistics centers; and (4) postal supplies and product sales, including private postal drop boxes, LED rotating warning lights, ultra-high brightness digital signage, signs/displays (including photocatalytic 'Light Paradise' air-purification products), and LED artificial-light plant growth systems. The company conducts its own product R&D and offers post-sale repair services for the products it sells.

The business model is sales-led and B2B-oriented, with primary revenue from Japan Post Group companies (Japan Post Co., Ltd. and Japan Post Transport Co., Ltd.) for service contracts, supplemented by product sales to external customers via a dedicated Product Development Sales Division in Tokyo, trade show participation (16th and 17th 販促EXPO in 2024 and 2025), and downloadable product catalogs. Pricing is not publicly disclosed and is contract-based. Geographic reach is exclusively domestic (Japan), and revenue figures are not publicly reported.
