## 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](https://asiaproxies.com/acceptable-use/).

## Which Japanese carriers can I choose?

You pick the carrier on 7-day and 30-day ports, subject to live stock.

| Carrier | Operator | Dedicated port | Rotating data |
| --- | --- | --- | --- |
| NTT Docomo | NTT | Yes, subject to stock | Yes |
| au | KDDI | Yes, subject to stock | Yes |
| SoftBank | SoftBank Corp. | Yes, subject to stock | Yes |
| Rakuten Mobile | Rakuten Group | Yes, subject to stock | Yes |

## 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](https://asiaproxies.com/residential-proxies/japan/) cost less per GB and add city targeting.

## 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](https://asiaproxies.com/guides/setup/).

*Rotate a Japanese port and confirm the new IP*

```bash
# PORT = the port number of your Japanese modem (see dashboard)
PROXY="http://USERNAME:PASSWORD@gw.asiaproxies.com: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
```

### Why does a Japan port cost more than an India port?

Japan is in our higher-cost group with Korea, Australia, New Zealand, Singapore, Hong Kong and Taiwan. That group has its own, higher port rate. India, Indonesia, Vietnam and other South and South-East Asian countries use the lower $59.25 monthly rate. Rotating mobile data has one price for all countries.

### Can I choose NTT Docomo or SoftBank?

Yes. NTT Docomo, au, SoftBank and Rakuten Mobile are available as a carrier choice on 7-day and 30-day ports, subject to live stock. Day ports do not include carrier choice. Rotating mobile data packs from 5 GB include carrier targeting. Tell support which carrier you need if stock looks low.

### Do I need to show ID?

No. AsiaProxies asks for no ID, no selfie and no documents. You pay in crypto and receive an account number, and email is optional. Use is still governed by our acceptable use policy. Banks, government portals and payment portals are blocked, and abuse leads to termination.

### Is traffic limited on a Japanese port?

No. A dedicated Japanese port has unlimited traffic for the paid period. Only you use the modem, so speed depends on the carrier signal and your own load. Rotating mobile data is billed per GB, and that traffic never expires. You can rotate the IP as often as your task needs.

### What if the port does not deliver a working IP?

Contact support with your account number; support replies within 12 hours. Our policy is a a full refund if you ask within 24 hours of the purchase and used under 100 MB of the pack; dedicated ports that never deliver a working IP are refunded in full. Refunds go as a credit back to your AsiaProxies balance, where it never expires. See the [refunds page](https://asiaproxies.com/refunds/) for the full terms.
