What Sata Construction does

Sata Construction is a Japanese construction engineering company founded in 1920 and headquartered in Maebashi, Japan. The firm is publicly listed on the Tokyo Stock Exchange under ticker symbol tyo:1826 and operates with a stated workforce of 251–500 employees. According to the input financial dataset, Sata Construction generated $36.8B in revenue in 2026, up from $26.7B in 2022, with EBITDA expanding from $673M to $1.74B over the same period and net income reaching $964M in 2026. Gross profit grew from $2.2B (2022) to $3.9B (2026), implying gross margin expansion from approximately 8.3% to 10.6%. Enterprise value is reported at approximately $5.6B across the five-year window, which is notably low relative to the revenue base and warrants scrutiny of the dataset's unit conventions.

Aggregated source material also references a digital platform branded as Genba-mado (現場の窓口 / "The Window of the Site"), a free contractor-matching service connecting customers across all 47 Japanese prefectures with vetted demolition, asbestos inspection, soil contamination, and industrial waste processing contractors. The platform claims 2,500+ registered contractors (32% screening pass rate), 150,000+ cumulative service requests, 97.8% customer satisfaction, a 4.8/5.0 score, an average 2-hour contractor response time, and average customer cost reduction of ¥470,000. One source attributes platform operation to Godo Kaisha Radineer (合同会社Radineer), a private Japanese LLC, which suggests the platform is either a subsidiary, an affiliated digital venture, or potentially misattributed data relative to the public-company construction profile in the firmographics; the discrepancy should be flagged before relying on either characterization alone.

Business model mechanics are affiliate-referral based: the platform serves customers at zero cost (no quote fees, no success commissions) and monetizes through registered contractor partnerships. Distribution is product-led growth via a 24/7 self-serve web platform supplemented by phone consultation (9:00–18:00 weekdays), with content marketing, SEO-optimized prefecture pages, and an AI cost diagnosis tool feeding top-of-funnel demand. Customer segments are primarily individual property owners, real estate investors, and property managers — a horizontal, long-tail persona with no enterprise anchor concentration.
