Japan 4G/5G mobile proxy on NTT Docomo, au, SoftBank and Rakuten Mobile

What is a Japan 4G/5G mobile proxy?

A Japan 4G/5G mobile proxy is a modem with a Japanese SIM card that relays your traffic. Websites see an IP address from NTT Docomo, au, SoftBank or Rakuten Mobile, like a phone user in Japan.

AsiaProxies is an Asia-Pacific proxy provider: residential and 4G/5G mobile IPs in Japan, Korea, India, Indonesia, Vietnam, the Philippines, Thailand, Singapore and Australia, paid in crypto with no KYC. Japan uses our higher-cost group rate, shared with Korea, Australia, New Zealand, Singapore, Hong Kong and Taiwan.

The modem connects over 4G LTE, or 5G where the carrier and the modem support it.

Why do Japanese sites accept mobile carrier IPs?

Japanese sites accept mobile carrier IPs because many real smartphone users share them. Carriers use carrier-grade NAT (CGNAT), which puts many subscribers behind one public IPv4 address.

A site that blocks a CGNAT address also blocks its own Docomo or SoftBank customers. That is why sites judge mobile traffic by behaviour rather than by address.

Use this for an honest local view, not for pressure on a site. Keep request rates low and follow our acceptable use policy.

Is a dedicated port or rotating mobile data better for Japan?

A dedicated port is better when you need one Japanese modem for long sessions with unlimited traffic. You decide when the IP changes. It fits app tests on Docomo or au, and checks of mobile ad placements.

Rotating mobile data is better when you need many Japanese mobile IPs at moderate volume. It costs from $0.90/GB, and the traffic never expires.

For bulk catalogue checks, Japan residential proxies cost less per GB and add city targeting.

How much does a dedicated Japan 5G mobile proxy cost per month?

How do I get a new IP on a Japanese port?

Call the rotation URL of the port. The modem reconnects to the same Japanese carrier and receives a new IP within seconds. Check the new IP before you continue. Browser and tool settings are in the setup guide.

# PORT = the port number of your Japanese modem (see dashboard)
PROXY="http://USERNAME:[email protected]:PORT"

curl -s -x "$PROXY" https://ipinfo.io/ip; echo

# Replace {port} and API_KEY, then request a new IP
curl -s "https://asiaproxies.com/api/v1/mobile/{port}/rotate?key=API_KEY"
sleep 10

curl -s -x "$PROXY" https://ipinfo.io/ip; echo
