IP Geolocation & Network Routing in Japan

IP address allocation and routing in Japan are managed by regional internet registries (such as APNIC for Asia-Pacific or RIPE NCC for Europe) and local internet service provider configurations. The accuracy of city-level IP geolocation in Japan is generally very high—exceeding 90% for fixed-line broadband connections and around 70-80% for cellular networks.

The largest telecommunication networks and ISPs in Japan include NTT Communications (OCN), SoftBank Corp, KDDI (au), and Rakuten Mobile. When checking an IP from these network blocks on IPLocatorTools, you can instantly trace its registered Autonomous System Number (ASN), ISP organization details, and physical geographical coordinates plotted on our dark-styled map.
