PLANET

What PLANET does

PLANET is a Tokyo-based private Japanese IT services company founded in March 1989 that provides custom system development, with a primary specialization in financial systems for life insurance and casualty insurance companies. The company delivers full lifecycle services spanning upstream requirements analysis through downstream implementation, covering both legacy mainframe environments and modern web-based systems, supplemented by computer hardware sales and registered specialized dispatch (tokutei haken) of IT personnel. Its customer base centers on Japan-based insurance and financial institutions, with Meiji Yasuda Life Insurance and its IT subsidiary Meiji Yasuda System Technology identified as primary relationships, alongside a broader set of system integrator partners including IBM Japan, HS Information Systems, and Computer Science.

The company operates from a single Tokyo office (Shibuya/Shoto area) with a registered address in Ota-ku and maintains a small workforce of 24 employees as of April 2025, with registered capital of ¥10 million. Its go-to-market is direct enterprise B2B sales into financial institutions, supplemented by partnerships with major system integrators for project staffing. Pricing is quote-based and negotiated individually per engagement, with no public pricing or SaaS-style recurring component disclosed; the revenue model is built on professional services fees, hardware resale margins, and dispatch billing.

PLANET's technology stack spans mainframe through web systems; no proprietary platforms, AI/ML capabilities, APIs, mobile applications, patents, or external investment activity are disclosed. The company's recruitment and corporate communications are conducted via its WordPress-based website, Mynavi new-graduate hiring platform, and an Instagram employer-branding account launched in November 2025. Operations are domestic-only, with no stated international footprint, and a privacy policy aligned with Japan's personal information protection regulations (last revised June 2023) is maintained under a designated Personal Information Protection Manager.
