Business Details

Since its founding in 1997, the company has developed an integrated manufacturing-and-sales business, starting from brokerage of new detached housing sales and expanding to encompass land acquisition, construction, and sales all within the group. Through sales centers in Tokyo, Kanagawa, Aichi, Saitama, Fukuoka, Chiba, Osaka, Hyogo, Gunma, and other areas, the company supplies reasonably priced new detached housing in highly convenient urban locations, targeting dual-income households and similar customers as its primary market. The segment consists of five sub-segments: Real Estate Brokerage (Open House), Detached Housing Development & Sale (Open House Development, Hawk One, Meldia), and Construction Contracting (Open House Architect).

Recent Overview

Continued strong demand for detached housing in urban areas resulted in year-on-year growth in both revenue and operating income

In H1 FY2026 (ending March 2026) (October 2025 to March 2026), revenue reached ¥380,930 million (up 5.5% year on year), and operating income reached ¥43,118 million (up 5.3% year on year). Demand for detached housing remains high in the urban areas where the group operates, and sales contracts leading to future deliveries are progressing favorably. The company continues to strengthen its purchasing power, product competitiveness, and sales capabilities through its integrated manufacturing-and-sales system.
