# Contracts, Agreements, and Intellectual Property in Japan — Overview

This section covers civil contracts in Japanese business and intellectual property protection together: non-compete practice in IT consulting, the importance of written NDAs and work rules when hiring, the historically loose interpretation of contracts in Japan, real disputes over construction and rental contracts, hidden tax risks in consultant contracts, statutory limits on a hired director's authority, the status of third-party litigation funding, the absence of classic patent trolling alongside aggressive brand defense by large companies, patenting of game mechanics, a court precedent on an ISP's liability for piracy, an assessment of copyright in game development, protection of dual-use technology at universities under FEFTA, and insurance for developers. See: Non-Compete, NDA, and Contract Interpretation Practice in Japan; Tax, Governance, and Litigation-Funding Risk in Contracts; Patents, Copyright, and Legal Protection of IP in Japan. Housing and office rental agreements are covered in a separate section.
