Heart Connection

What Heart Connection does

Heart Connection Co., Ltd. (ハートコネクション株式会社) is a privately held Japanese systems integrator founded in Sendai on February 10, 1993, with a secondary branch in Fukuoka. The company designs, builds, and sells custom computer systems for enterprise and public-sector clients across seven vertical solution areas: electric power (billing, distribution, equipment ledgers, supply-demand planning), local government (water/sewage billing, fixed asset tax, comprehensive tax administration), telecommunications (revenue management), construction and manufacturing (estimation, cost management, factory automation), distribution and retail (inventory and product management), financial services (sales support, P&L analysis, securities and trading systems), and other verticals including hospital reservation systems.

The underlying technology is built on legacy enterprise foundations: Oracle database design and construction, Java, VB.NET, and C++ programming, deployed in UNIX environments, with web-based business systems development capability. The company holds a specific temporary worker dispatch business license obtained in 2003. Its go-to-market is direct enterprise field sales through a sales department (営業部), and publicly disclosed customer relationships are dominated by Japan-based IT services firms such as NTT Data Tohoku, Fujitsu Banking Solutions, Techno Mind, and Asahi System, suggesting a subcontractor-driven revenue model rather than direct end-client sales.

Heart Connection operates with ¥10 million in registered capital, a September fiscal year-end, banking relationships with 77 Bank, Sendai Bank, and Mizuho Bank, and is led by Representative Director Hayasaka Fujiyuki, who also serves as Personal Information Protection Manager. The company maintains no public funding history, no acquisitions, no patents, no awards, and no disclosed AI or cloud-native technology investments, positioning it as a stable, narrowly regional systems integrator rather than a growth-stage software vendor.
