Explanation
Among the given options, Japan has its own Satellite Navigation System. Japan's system is called the Quasi-Zenith Satellite System (QZSS), also known as Michibiki. While QZSS is primarily an augmentation system for GPS, designed to improve the accuracy and availability of satellite positioning for users in Japan and the Asia-Oceania region, it is considered Japan's own national satellite navigation capability. Other countries listed (Australia, Canada, Israel) primarily rely on global systems like the United States' GPS, Russia's GLONASS, or the European Union's Galileo, and do not possess their own independent satellite navigation constellations.
