# Best static mobile proxies for Japan in 2026: one carrier address, held a full day, paid per GB

Static mobile, done the smart way. **QuanticData holds one Japanese carrier address for you for up to 24 hours**, on NTT Docomo Business, NTT Docomo and au (KDDI) by name, and bills the traffic rather than the port: $5 for 1 GB, no modem rental, no monthly fee. Below, the dedicated ports priced on 9 November 2026, the break-even in gigabytes a day, and where a port wins.

## The verdict for Japan

"Static mobile proxy" means two products, and we sell the one that wins the arithmetic for most buyers. A **dedicated port** is one modem and one Japanese SIM rented to you, priced per port whatever you push through it, on whichever operator the shop has in stock that week. A **sticky session** is one address from a carrier pool reserved for your session ID, priced per gigabyte, operator chosen by name. **QuanticData sells the second**: NTT Docomo Business, NTT Docomo and au (KDDI), held for up to 24 hours per session ID, $5 for 1 GB down to $2.30/GB, no port fee, no device rental. Need a dedicated Japanese port anyway?

Port or session is arithmetic, not taste: a port pays off only when one account pushes more gigabytes a day through one IP than the port costs in gigabytes at our rate. The table does the sum with the port prices we read.

The sum, in four lines

- **Hold**: up to 24 h per session ID
- **Cheapest port we read**: $3.00 a day (HydraProxy)
- **Break-even at $2.30/GB**: 1.3 GB a day through one IP
- **Operator**: chosen by name, kept with the session

## Static mobile for Japan: sticky sessions against dedicated ports

Prices read from the three sellers' public pages on 9 November 2026; whether a Japanese port is in stock on a given day is a question for their stock pages. Break-even is the port price divided by $2.30, the QuanticData rate at 500 GB; at the $5 entry rate the thresholds are 2.2 times lower.

| Criterion | QuanticData sticky session | HydraProxy | ProxyEmpire | VoidMob |
| --- | --- | --- | --- | --- |
| What you buy | one carrier address held up to 24 h per session ID, on NTT Docomo Business, NTT Docomo and au (KDDI) | a dedicated mobile port | a dedicated mobile port | a dedicated mobile port, or shared mobile per GB |
| Published price | $5 for 1 GB; $2.30/GB at 500 GB | $3.00 a day per port | $125 or $250 a month per port; $20 day pass | dedicated from $49 a month; a US port $129 a month; shared $3.99/GB |
| Cost per day over a month | what you use: 0.5 GB a day is $1.15 at the 500 GB rate | $3.00 | $4.17 or $8.33 | $1.63 (from $49) to $4.30 (US port) |
| Break-even in GB a day at $2.30/GB | none: you pay for traffic only | 1.3 GB | 1.8 or 3.6 GB | 0.7 to 1.9 GB |
| Japanese carrier named | yes: NTT Docomo Business, NTT Docomo and au (KDDI) | whichever port is in stock | whichever port is in stock | whichever port is in stock |
| Minimum purchase | $5, one-off | one day | one day pass | one month on dedicated |

Among the large networks, Oxylabs states 24-hour mobile sessions on its pricing page (30 October 2026) at $7.5/GB on a $30 a month plan; IPRoyal and Bright Data state no session length there. A 24-hour hold at $5 for the first gigabyte is the row to beat for a Japanese account that works a full day on one address, and it is ours.

## What you hold for Japan, and what you pay

Everything lives in the username. `-sid-` names the session, `-ttl-` sets how long the address is held, up to 1,440 minutes. One session ID per account, kept for the life of the account, and the address stays as long as the device behind it stays connected; if it drops, the next request on the same ID gets a fresh address on the same carrier, exactly what a dedicated port does when its modem reconnects. The mobile pool exceeds 500k IPs worldwide.

The [Japan mobile proxies page](https://quanticdata.io/mobile-proxies/japan/) lists every city with its operators; the [antidetect comparison](https://quanticdata.io/best/mobile-proxies-for-antidetect-browsers/) explains one sticky session per browser profile.

## When a port beats a session, and when it does not

Buy a port when one identity must keep one Japanese address for weeks without a 24-hour boundary, when the traffic through it is heavy and continuous, or when you need to trigger the rotation yourself from an API at a moment of your choosing. Buy sticky sessions when accounts are many, traffic per account is light, the day is the natural unit of work, and you want the operator chosen by name across 9 regions rather than whichever SIM the shop has left.

If the sum says port, say so to us: a dedicated Japanese mobile port is quoted as a custom plan, operator and term of your choice, through the same account and the same payment methods.

## Holding a Japanese mobile address in one line

Host and port are shown in the dashboard after purchase; `USER` and `PASS` stand for the credentials.

```bash
# one NTT Docomo Business address, held for 24 hours under the session ID "shop01"
curl -x "$PROXY_HOST" -U "USER-country-jp-isp-ntt_docomo_business-type-mobile-sid-shop01-ttl-1440m:PASS" https://ipinfo.io/json

# the same, over SOCKS5, for a browser profile
curl --socks5-hostname "USER-country-jp-isp-ntt_docomo_business-type-mobile-sid-shop01-ttl-1440m:PASS@$PROXY_HOST" https://ipinfo.io/json
```

Run the first line twice and the same address comes back. Change the session ID and NTT Docomo Business hands you a new one.

[Something else? Ask us](https://quanticdata.io/best/static-mobile-proxies/japan/#ask)

### Does QuanticData sell static mobile proxies for Japan?

Yes, as sticky mobile sessions: one address on NTT Docomo Business, NTT Docomo and au (KDDI), held for up to 24 hours per session ID, per GB from $5 for 1 GB with no port fee. A dedicated Japanese port on a single device is not a catalog product; it is quoted on request as a custom plan.

### What is the difference between a static mobile proxy and a sticky session?

A dedicated port is one modem and one SIM reserved for you, priced per port whatever you push through it. A sticky session is one address from a carrier pool reserved for your session ID for a set time, priced per GB. The site sees the same thing either way, a Japanese carrier address that does not change during the session; what differs is how long it is held and how you pay.

### How long can a Japanese mobile address be held?

Up to 1,440 minutes (24 hours) per session ID on QuanticData, as long as the device behind it stays connected. Keep the ID for the next day and you get a fresh address on the same carrier; most accounts tolerate a daily change on the same network, which is what a phone does when it reconnects.

### Is a dedicated port cheaper than paying per GB?

Only above a threshold. On 9 November 2026 HydraProxy priced a port at $3.00 a day, ProxyEmpire at $125 or $250 a month and VoidMob dedicated from $49 a month; at QuanticData's $2.30/GB rate those ports break even at 1.3, 1.8 to 3.6, and 0.7 GB a day through the one IP. Below that, sticky sessions cost less; above it, ask us for a custom plan.

### Can I pick NTT Docomo Business, NTT Docomo or au (KDDI) for the held address?

Yes: -isp-ntt_docomo_business, -isp-ntt_docomo, -isp-au_one_net in the username, kept constant with the session ID. A port shop gives you whichever SIM it has in stock.
