Buy Japanese proxies. Ready in minutes.

Japan quietly moved its home broadband onto a design most other countries never adopted. New connections run IPv6 natively and carry their IPv4 over the top of it, and the IPv4 transport is handled by a separate operator rather than the retail ISP. The practical result is that a Japanese residential IPv4 is commonly a shared address: several households sit behind one public IP, and on the most common setups each home gets only a small fixed budget of source ports. Bandwidth is not the limit; the number of simultaneous outbound connections is.

For proxy work that changes what a Japanese residential address even means. The reputation attached to a shared IP is collective, so it reflects everyone behind it, not one household. This is not a flaw to hide, it is the reason a dedicated Japanese address earns its place: an ISP or residential line held for you behaves like one home instead of a slice of a shared gateway. the live picture on our free list is where you see the free pool's real makeup rather than a headline number.

First, a clarification this market genuinely needs: in Japan the word "proxy" usually means a shopping intermediary, a service that buys an item on your behalf from a Japanese site and reships it abroad. That is not this. This page is about Japanese IP addresses, network routes that make your own tools appear to browse from inside Japan.

Most of that work is commerce data. Japan runs one of the world's largest second-hand and C2C economies, led by Mercari and Yahoo Auctions, so a lot of Japanese-IP work is tracking listings, prices and availability across those platforms and the big B2C shops. Search tracking sits beside it: google.co.jp now redirects to google.com, so the domain no longer picks the country and a Japan-resolving IP is what returns a genuinely local result. The same holds for Yahoo Japan, which has run on Google's search backend for years. Streaming and app QA round it out, verifying that a Japan-only catalogue or release behaves for a Japanese viewer. The automated version of all of this can run through a Japanese exit on our scraper APIs.

For Japan we offer dedicated residential, static ISP and datacenter addresses, and the cards below only appear because the live catalog confirms each one for Japan right now. We do not currently sell a dedicated Japanese mobile product, so you will not see a mobile card here, and we would rather show you three real options than a fourth that we cannot actually deliver. Residential and ISP are the ones that answer the shared-address problem above, because they give you a Japanese line that behaves like a single household.

On the rules: Japan's personal-data law is the APPI, and the Unauthorized Computer Access Act draws the hard line at getting into systems or accounts you were not cleared for. Collecting genuinely public information is a different thing from either. Our terms ask you to stay on the right side of that line and of each site's own rules, and to treat anything involving personal data or a login as the serious question it is.
