PeeringDB records 11 internet exchanges in Tokyo, with 1,186 peering records across them. BBIX Tokyo is the best connected at 356 participants, ahead of JPIX TOKYO at 270 and JPNAP Tokyo at 245. Another 891 network presences sit in 47 colocation facilities. A Tokyo IP address records where an operator registered the block rather than where a device sits.
Internet exchanges in Tokyo
An exchange is a shared switch where networks hand traffic to each other directly. Participant counts come from PeeringDB, where each network maintains its own record.

What a Tokyo IP address tells you
Tokyo holds 11 exchanges and 1,186 peering records in PeeringDB. BBIX Tokyo lists 356 participants, JPIX TOKYO 270, JPNAP Tokyo 245 and Equinix Tokyo 126, while the smaller exchanges run from BGP.Exchange - Tokyo at 63 participants down to JEIX at 6. Colocation carries similar weight, with 891 network presences across 47 facilities. AT TOKYO (CC1/CC2) and Equinix TY8 record 140 networks each, Equinix TY2 records 115, and the NTT DATA Otemachi and Telehouse Otemachi buildings record 46 and 44.
The carrier registry for Japan lists no mobile operator ASNs, so none of the country's mobile networks is matched to a Tokyo exchange in this data. BBIX Tokyo, JPIX TOKYO, JPNAP Tokyo and Equinix Tokyo do each carry a handful of carrier ASN records, but the exchange listing alone does not name the operators behind them. An address that geolocates to Tokyo therefore reports an operator's registry entry, not the position of a handset or a server.
Geolocation databases read the location an operator publishes for an address block, and a Japanese operator with a Tokyo registry record can announce that block from anywhere it runs a gateway. Mobile traffic in particular leaves through a small number of gateways, so a subscriber far from the city still shows a city address. Anyone checking an address should read the origin ASN and the netname on the specific prefix, then compare that against the exchange and facility records above.
Questions
Which internet exchanges are in Tokyo?
PeeringDB lists 11. BBIX Tokyo has 356 participants, JPIX TOKYO 270, JPNAP Tokyo 245 and Equinix Tokyo 126. Below those sit BGP.Exchange - Tokyo at 63, TYIX at 37, ENTERNET IX at 28, DIX-IE and Protocol 7 IX - Lycheen Japan at 23 each, Protocol 7 IX - Tokyo at 9 and JEIX at 6.
Do Japanese mobile carriers peer in Tokyo?
The carrier registry used here holds no mobile operator ASNs for Japan, so the question cannot be answered from this data. Four of the Tokyo exchanges do record carrier ASNs among their participants, but this data does not name the operators behind those ASNs.
Does an IP that geolocates to Tokyo mean the device is there?
No. The address block carries the location its operator published in a registry record, and routing can announce that block from another site entirely. With 891 network presences in 47 Tokyo facilities, the city address narrows the operator far more than it narrows the device.
