Japan datacenter proxies: dedicated IPv4 by city

How many IPv4 addresses does Japan have?

APNIC, the regional internet registry for Japan, had delegated 188,705,088 IPv4 addresses to organisations in Japan by 19 October 2026. That is 5.12% of all IPv4 space delegated worldwide and ranks Japan 3rd of 240 countries and territories. Among the 22 countries on RackProxies it comes 2nd, after United States (1,606,309,024) and before United Kingdom (138,720,064).

Every free pool of IPv4 has run out, so a Japan datacenter IP is a scarce, leased resource: that is why datacenter proxies are billed per IP and per month rather than per GB. Japan also holds 10,224 IPv6 blocks of /32 size and 1,305 ASNs (network numbers). RackProxies sells IPv4 only; IPv6 is not sold yet.

Where are the datacenters in Japan?

Tokyo and Osaka are the two Japanese hubs, usually used together for redundancy. PeeringDB listed 113 colocation facilities and 27 internet exchange points in Japan on 19 October 2026. The exchanges with the most connected networks are BBIX Tokyo (355), JPIX TOKYO (272) and JPNAP Tokyo (251).

In Japan, the buildings where the most networks are present are Equinix TY8 - Tokyo in Tokyo (147 networks), AT TOKYO (CC1/CC2) in Tokyo (142 networks), Equinix TY2 - Tokyo in Tokyo (117 networks) and Equinix OS1 - Osaka in Osaka (71 networks). The operators with the most facilities there in PeeringDB are NTT DOCOMO BUSINESS (16), Equinix (14), Digital Realty (9) and Digital Edge DC (7).

Which IP will a Japan datacenter proxy give me?

You get an IPv4 address announced by a hosting or transit network in Japan, fixed for 30 days and assigned to you alone. A lookup of its network shows a hosting ASN registered with APNIC, not a Japan home broadband provider. Most databases place it in Japan, often in Osaka; to confirm, run the datacenter IP check.

Which law applies when you collect data from Japan sites?

Japan's Act on the Protection of Personal Information (APPI) applies, overseen by the Personal Information Protection Commission. If you collect personal data from Japan websites, these rules apply to you whatever IP you use. RackProxies is for public, non-personal data, tests of your own services and allowlisted access; the acceptable use policy lists what is blocked. Not legal advice.

How much do Japan datacenter proxies cost?

As of October 2026, a Japan datacenter IP costs $1.29 for 30 days, the same price as every other country on RackProxies; 100 IPs cost $59.25 ($0.59/IP). Prices are per IP and per 30-day rental, not per GB.
