Abstract
Global Navigation Satellite Systems (GNSS), including the Global Positioning System (GPS) of the USA, are widely used today, but legal liabilities for damage to users which could arise from relying on GNSS signals are unclear and being discussed outside Japan. The Japanese government is currently developing its own global navigation system, the Quasi Zenith Satellite System (QZSS), so analysis under Japanese law is of value. In this article the authors examine, through case studies, liabilities resulting from errors in the signals emitted from the QZSS, and from the termination of QZSS signals, from the Japanese law perspective.
