What Construction Data does
建設データ株式会社 (Construction Data Co., Ltd.) is a privately held Japanese information-services company headquartered in Taito Ward, Tokyo, that operates as a group company of 日本工業経済新聞社 (Nihon Kogyo Keizai Shinbunsha), a construction-industry newspaper publisher active in the Kanto-Koshinetsu region. Its core offering is 入札ネット (Nyusatsu Net), a subscription-based public-works bidding information delivery service that aggregates public procurement notices from entities including the Ministry of Land, Infrastructure, Transport and Tourism (国交省) and the Kanto Regional Development Bureau, and exposes them through keyword search, email alerts, publisher (発注者) selection, rival-company analysis, and Excel/CSV data export, with single-device/browser authentication as a security control.
The product portfolio follows a platform-plus-modules architecture: the core 入札ネット service is extended by a premium tier (入札ネット+α), a document and reference library (建設資料館), a building-construction email notification service (建築工事情報@mail), a specialized construction newspaper (建設専門新聞), a content production service (コンテンツ制作), and the 建設データジャーナル web media covering industry news and management topics. The company monetizes primarily through annual subscriptions on the standard and premium tiers, supplemented by targeted banner advertising on the Nyusatsu Net platform and print/digital newspaper revenues.
Go-to-market is sales-led and direct, targeting Japanese construction firms and industry professionals seeking public-works bidding opportunities, competitor intelligence, and industry news. Acquisition channels include a self-serve web-based free trial for first-time 入札ネット users, inside-sales phone support (03-3823-6006), web inquiry forms, an email newsletter, the company blog, and the parent group's established Kanto-Koshinetsu construction-newspaper distribution network. The company's geographic footprint is domestic Japan, with operational concentration in the Kanto region inherited from the parent group's coverage area.
