Shinnihon Corporation

What Shinnihon Corporation does

Shinnihon Corporation (新日本建設株式会社) is a Japanese real estate developer and general construction company founded in 1964, headquartered in Chiba Prefecture with a Tokyo branch office. The company develops and sells newly constructed residential condominiums under the "Excellent City" (エクセレントシティ) brand across the Greater Tokyo metropolitan area — including Tokyo, Kanagawa, Chiba, and Saitama prefectures — and operates sub-brands Excellent Square, Excellent Grace, Excellent THE RESIDENCE, and Excellent THE TOWER. As of March 2025, the company has cumulatively delivered more than 313 buildings and 15,000 units, and in 2024 it ranked #6 among developers/owners and #2 among construction companies in the Greater Tokyo metropolitan area rankings by Marketing Corporation.

The company's core technology centers on Japanese reinforced-concrete (RC) construction executed through an in-house one-stop system that retains land acquisition, planning, design, construction, sales, design changes, and after-sales service within a single entity. Notable proprietary features include ZEH-M Oriented energy certification achieving 20%+ primary energy reduction through enhanced insulation and high-efficiency equipment, the "Excellent Water Plus" whole-house purification system, the Outframe construction method that eliminates interior columns, double-staggered reinforced steel bar exterior walls, and an extended 5–15 year structural warranty (versus industry-standard 2–10 years). The wholly-owned subsidiary Shinnihon Community Co., Ltd. handles ongoing condominium management.

Revenue is generated primarily through one-off condominium unit sales (typical project pricing ¥3,600万–¥7,998万 / roughly $240K–$530K USD per unit) and supplemented by contract construction work for major Japanese developers including Nomura Real Estate and Mitsui Fudosan Residential. The go-to-market is direct-to-consumer through company-operated model rooms and guest salons across four prefectures, supported by listings on SUUMO, LIFULL HOME'S, Yahoo! Real Estate, and at home, alongside traditional print, billboard, station, and in-train advertising and an owned Tomonokai referral community. Secondary recurring revenue is captured through monthly management fees (¥10,300–¥23,000/unit) and reserve fund contributions managed by the subsidiary. The company holds ISO 9001, ISO 14001, Durability Grade 3, CASBEE Kanagawa, CASBEE Saitama, and F★★★★ formaldehyde certifications.
