Fuso Holdings

What Fuso Holdings does

FUSO Group Holdings Co., Ltd. is a privately held Japanese holding company headquartered in Tokyo (registered head office relocated to Takamatsu, Kagawa Prefecture in April 2026 under a dual-headquarters structure). Founded in 1946 as Shikoku Sangyosha and operating across approximately 10 domestic subsidiaries plus overseas entities in the United States, Vietnam, and Fiji, the group organizes its business around three domains: water infrastructure, housing and equipment, and renewable energy.

The water infrastructure domain is the core franchise. FUSO Inc. and FUSO Maintenance Tech design, construct, and operate municipal water purification plants, sewage treatment facilities, and pipe distribution networks; Aqua Pipe Tech distributes approximately 1,000 types of water pipe materials through a Sapporo logistics center; and the in-house Steel Pipe Factory in Takamatsu manufactures ductile iron pipes. Notable proprietary technology includes a Zinc Prussian Blue (ZnPB) ammonia nitrogen adsorption material co-developed with AIST that achieves 500+ adsorption/desorption cycles, BIM/CIM 3D modeling recognized by MLIT, and an audio-analysis leak-detection partnership with wavelogy. The group also holds Japan's first BT+Concession water utility participation (Toyohashi) and operates a long-term Kagawa wide-area O&M contract worth JPY 4.88B over five years.

Commercial channels span enterprise field sales to municipal governments via competitive public tender, business-to-business sales of renewable energy aggregation services (RE100 Denki), and direct-to-consumer housing sales through brands including sakura Yume House (achieving #1 in Kagawa Prefecture housing starts for FY2024), emitas, Jibun House, Forkul, and Concept House X. Revenue is generated from one-time design-build contracts, managed-services O&M engagements, electricity sales and aggregation fees (5% commission), and unit-priced home sales starting from JPY 7.68 million. The group is expanding an aggregated 100MW/400MWh battery storage pipeline by FY2027 and a US water infrastructure presence via FUSO America Corporation.
