What Forest of people does

人の森株式会社 (Hitonomori Corporation, branded in English as 'Forest of people') is a privately held, family-controlled Japanese diversified conglomerate headquartered in Ebina City, Kanagawa Prefecture, with operations tracing back to 1940 as a quarrying business. The company operates across at least seven distinct revenue streams: (1) Fitness and spa club operations under the COCOKARA (ココロカラ) brand with four facilities in Kanagawa Prefecture plus the Harenochi Hare (晴れのち晴れ) padel/futsal/tennis sports complex in Chiba; (2) Construction materials production — JIS-certified aggregates, crushed stone, and ready-mix concrete — anchored by the 50+ year-old Kegon Factory (華厳工場) quarry in Atsugi; (3) Civil engineering and construction services under ISO9001:2015 certification, executing road, bridge, river, and building projects primarily for government clients including 国土交通省, 神奈川県, and 海老名市; (4) Water treatment systems including industrial-scale groundwater membrane filtration and the consumer RO Server (みずから) product; (5) Real estate management covering monthly parking, coin parking, land/building rental, and the Atsugi Iiyama Campsite; (6) Geological survey and non-destructive testing services using ground-penetrating radar; and (7) LED-based fully artificial-light plant factory strawberry production, operated as the first such facility in the Kanto region since September 2018.

The company employs 160+ staff (including part-time workers) and reports annual sales exceeding 9億円 (approximately $6M USD) as of May 2025, with stated 自己資本 (equity capital) of approximately 103億円. Ownership is concentrated in the Kato family, with 加藤政徳 serving as Representative Director and President since 2004. Two wholly-owned subsidiaries — 藤野交通株式会社 (Fujino Kootsu, taxi transportation) and 株式会社つなぐ力 (Tsunagu Chikara, gravel and sand extraction, formerly Sagami Bussan) — extend the operational footprint. Distribution is direct: field sales for B2B construction and water-treatment projects, owned retail for B2C fitness, and a mixed channel approach with corporate website, Instagram (corporate and recruitment-dedicated), Facebook, YouTube (Kegon Factory product education), PR Times distribution, and Mynavi for new-graduate recruitment. The company's strategic positioning centers on a values-based culture codified through 14 DNA principles and Design Thinking integration formalized via the 2023 Design Strategy Division.
