Descriptiontext

Yamato Corporation (株式会社ヤマト, TYO:1967) is a publicly listed Japanese one-stop 'construction product' company founded in 1945 and headquartered in Maebashi, Gunma Prefecture, employing 1,001–5,000 people. The company delivers integrated energy, water, and air infrastructure solutions across the full lifecycle — basic planning, design, construction, maintenance, asset management, partial operations, and financing — for medical/welfare facilities, government/public buildings, food retail and cold-chain, hospitality/bath/leisure, water/sewage infrastructure, education, factories, and automotive dealerships.

The technical platform rests on three proprietary pillars: (1) large-temperature-difference thermal storage air conditioning and the patented Operation Management System (Patent 2744758), which achieves ΔT of 9–11°C and ~80–86% reduction in water conveyance power; (2) the CO2 Ultra Eco Ice System (Patent 6582102), a natural-refrigerant brine-cooled ice thermal storage system targeting supermarkets and food factories, eligible for the Ministry of the Environment natural-refrigerant subsidy and exempt from Japan's Fluorocarbons Emission Control Act; and (3) TASKPLUS, an IoT-based wide-area remote monitoring network using FOMA/LTE/internet that provides cloud-based centralized monitoring, alarm email notification, trend graphs, customizable XML reports, and equipment-ledger management for installed equipment. Complementary proprietary technologies include the High-Freshness Refrigeration System (2020 JSRAE Technology Award), CO2 Brine Chiller Units, UV disinfection ('I Water Pure' — OEM via Iwasaki Electric), hollow-fiber membrane filtration ('Pureria' — OEM via Kuraray), the Yamato Super Chlorination System (Legionella countermeasure), small hydroelectric power support, and solar PV systems, all monitored by TASKPLUS and supported through the in-house Yamato Analysis Center and Asakura Processing Center (150+ units/year of proprietary fabrication).

The revenue model combines one-time construction and engineering project revenue with a meaningful recurring-revenue tail: ESCO Energy Service contracts under Guaranteed Savings and Shared Savings schemes, multi-year Energy Service subscriptions where Yamato finances equipment upgrades (no initial investment required from the customer) and bills a monthly service fee + energy cost, long-term PFI concessions via wholly-owned special-purpose companies (BTO/BOT/BOO), subscription-based TASKPLUS monitoring and Electronic Chart facility-information services, OEM equipment sales, and subsidy-application consulting. Distribution is primarily direct enterprise sales, supported by a 24/7 contact center (0800-800-7380), an Asakura-based Support Center/Showroom with 3DCG visualization and 20+ co-exhibiting manufacturers, and a partnership network (Green-kai / Kyoei-kai). The company holds ISO 9001 and ISO 14001 certifications and self-validates ZEB know-how through its BELS 5-star / Nearly ZEB Product Center office (BEI 0.12, 88% primary-energy reduction).

Yamato

Facility Construction & Environmental Engineering Servicesyamato-se.co.jp

Yamato Corporation (TYO:1967, founded 1945, Maebashi, Gunma) is a publicly listed Japanese one-stop facility construction and environmental engineering firm delivering HVAC, refrigeration, water treatment, ZEB consulting, and ESCO/PFI/Energy Service contracts across medical, government, food, hospitality, and industrial customers, anchored by proprietary thermal-storage and CO2-refrigerant technology and the TASKPLUS IoT monitoring platform.

What Yamato does

Yamato Corporation (株式会社ヤマト, TYO:1967) is a publicly listed Japanese one-stop 'construction product' company founded in 1945 and headquartered in Maebashi, Gunma Prefecture, employing 1,001–5,000 people. The company delivers integrated energy, water, and air infrastructure solutions across the full lifecycle — basic planning, design, construction, maintenance, asset management, partial operations, and financing — for medical/welfare facilities, government/public buildings, food retail and cold-chain, hospitality/bath/leisure, water/sewage infrastructure, education, factories, and automotive dealerships.

The technical platform rests on three proprietary pillars: (1) large-temperature-difference thermal storage air conditioning and the patented Operation Management System (Patent 2744758), which achieves ΔT of 9–11°C and ~80–86% reduction in water conveyance power; (2) the CO2 Ultra Eco Ice System (Patent 6582102), a natural-refrigerant brine-cooled ice thermal storage system targeting supermarkets and food factories, eligible for the Ministry of the Environment natural-refrigerant subsidy and exempt from Japan's Fluorocarbons Emission Control Act; and (3) TASKPLUS, an IoT-based wide-area remote monitoring network using FOMA/LTE/internet that provides cloud-based centralized monitoring, alarm email notification, trend graphs, customizable XML reports, and equipment-ledger management for installed equipment. Complementary proprietary technologies include the High-Freshness Refrigeration System (2020 JSRAE Technology Award), CO2 Brine Chiller Units, UV disinfection ('I Water Pure' — OEM via Iwasaki Electric), hollow-fiber membrane filtration ('Pureria' — OEM via Kuraray), the Yamato Super Chlorination System (Legionella countermeasure), small hydroelectric power support, and solar PV systems, all monitored by TASKPLUS and supported through the in-house Yamato Analysis Center and Asakura Processing Center (150+ units/year of proprietary fabrication).

The revenue model combines one-time construction and engineering project revenue with a meaningful recurring-revenue tail: ESCO Energy Service contracts under Guaranteed Savings and Shared Savings schemes, multi-year Energy Service subscriptions where Yamato finances equipment upgrades (no initial investment required from the customer) and bills a monthly service fee + energy cost, long-term PFI concessions via wholly-owned special-purpose companies (BTO/BOT/BOO), subscription-based TASKPLUS monitoring and Electronic Chart facility-information services, OEM equipment sales, and subsidy-application consulting. Distribution is primarily direct enterprise sales, supported by a 24/7 contact center (0800-800-7380), an Asakura-based Support Center/Showroom with 3DCG visualization and 20+ co-exhibiting manufacturers, and a partnership network (Green-kai / Kyoei-kai). The company holds ISO 9001 and ISO 14001 certifications and self-validates ZEB know-how through its BELS 5-star / Nearly ZEB Product Center office (BEI 0.12, 88% primary-energy reduction).

Yamato product offering

Product offering

Core offering

Yamato is a Japanese facility construction and environmental engineering company that delivers integrated air-conditioning, refrigeration, water-treatment, and renewable-energy infrastructure as a one-stop service covering planning, design, construction, maintenance, asset management, and financing. Core revenue comes from construction contracts, ESCO/Energy Service managed agreements, PFI concessions, and proprietary equipment (thermal-storage HVAC, CO2-refrigerant ice storage, brine refrigeration, UV/membrane water treatment), supported by the TASKPLUS IoT cloud-monitoring platform and in-house stainless-piping fabrication at the Asakura Processing Center.

Product overview

株式会社ヤマト (Yamato Corporation) is a Japanese one-stop "construction product" (建設プロダクト) company headquartered in Maebashi, Gunma Prefecture, that delivers integrated energy, water, and air infrastructure solutions from planning and design through construction, maintenance, and asset management. Rather than a single unified product, Yamato offers a portfolio of co-engineered modules grouped under four engineering pillars — Air-Conditioning / Sanitary Engineering (空調衛生エンジニアリング), Food-Distribution Engineering (食品流通エンジニアリング, led by the Ultra Eco-Ice and High-Freshness Refrigeration Systems), Environmental Engineering (環境エンジニアリング, covering filtration, UV, membrane, chemical-injection, and small-hydro power), and Solutions (ZEB implementation, ESCO, PFI, Energy Service, and subsidy support) — all tied together by the proprietary TASKPLUS cloud-based remote-monitoring and Electronic Chart facility-information platforms. The Yamato Construction Business stitches the modules together on a per-project basis (medical, welfare, education, office, public, lodging, factory, supermarket, food logistics, and water-treatment facilities) and the Yamato Contact Center and Asakura-based Support Center/Showroom provide 24/7/365 service and a "virtual + real" customer-experience facility for stakeholder alignment.
