The verdict for Japan
QuanticData is the best mobile proxy for Japan, and here is the catalog to prove it. On 20 September 2026 it listed 3 Japanese operators, NTT Docomo Business, NTT Docomo and au (KDDI), each selectable by name, across 9 regions and 9 cities. $5 for 1 GB, down to $2.30/GB at 500 GB, one-off packs valid 90 days, sessions rotating per request or sticky for up to 24 hours, no port fee, no device rental. The mobile pool exceeds 500k IPs worldwide.
A carrier address is what accounts, apps and antidetect profiles expect from a Japanese user: a NTT Docomo Business exit is shared with thousands of real subscribers. Scraping prices and listings instead? The rotating residential page for Japan does it for $1.00/GB. One address for a whole working day? The static mobile page shows the 24-hour hold.
Mobile proxies for Japan: the table
| Criterion | QuanticData | Oxylabs | IPRoyal | Bright Data |
|---|---|---|---|---|
| Countries | 199 countries and territories | 140+ countries | n/a | n/a |
| Japanese carriers by name | Yes: NTT Docomo Business, NTT Docomo and au (KDDI) | country and ASN targeting on its pricing page | country, region, city and ISP on its pricing page | n/a |
| Entry price | $5 for 1 GB | $7.5/GB on the $30 a month Starter plan | $6.80/GB for 2 GB | Not published: no mobile pricing page |
| Lowest price per GB | $2.30/GB at 500 GB, one-off | $3.5/GB from 714 GB | $5.20/GB at 100 GB | Not published |
| Subscription needed | No: one-off packs, valid 90 days | Yes: monthly plans from $30 | n/a | No: pay as you go is offered |

| Crypto and KYC | Card, PayPal or 300+ cryptocurrencies; no KYC | n/a | n/a | Cards, PayPal, wire; no crypto listed. Compliance check (KYC) before use |
Compare the session length before the price: Oxylabs states 24-hour sessions, IPRoyal and Bright Data state none on the pages we read, and a Japanese account that works an afternoon on one address cannot live on a two-hour hold whatever the rate. Ours holds for 24 hours, on the operator you name.

The Japan search results, read for you
Search "best proxies for Japan" and four of the top five results are about proxy shopping, forwarders that buy from Mercari or Yahoo! Auctions on your behalf, with "Japan Rabbit" and "best Mercari Japan proxy" in the related searches. The networking buyer gets a free-proxy list and little else. Not one result in the top five names the Japanese operators with the cities each one covers. This page does, and so does the Japan mobile page.
Japan is bought for marketplace and auction data (Amazon.co.jp, Rakuten, Mercari, Yahoo! Auctions), Japanese SERPs, app and ad checks, and account work on services that expect a domestic connection. Skip the free lists for anything with a login, and read the per-port offers with a calculator: at our 500 GB rate, a port at $3.00 a day only wins past 1.3 GB a day through that single IP; the per-GB versus per-port section on the mobile comparison has the full arithmetic.
A Japanese carrier address in one line
Host and port are shown in the dashboard after purchase; USER and PASS stand for the credentials. The username does the routing:
# mobile, rotating, any Japanese operator
curl -x "$PROXY_HOST" -U "USER-country-jp-type-mobile:PASS" https://ipinfo.io/json
# mobile, NTT Docomo Business only, sticky for 12 hours (one session ID per account)
curl -x "$PROXY_HOST" -U "USER-country-jp-isp-ntt_docomo_business-type-mobile-sid-acct01-ttl-720m:PASS" https://ipinfo.io/json
# mobile, Osaka, rotating
curl -x "$PROXY_HOST" -U "USER-country-jp-region-osaka-city-osaka-type-mobile:PASS" https://ipinfo.io/jsonThe response's org field names the operator. Keep the session ID constant for the life of an account; change it and you get a fresh address.

Which Japanese carrier should I pick?
Leave it out unless the target cares: USER-country-jp-type-mobile rotates across NTT Docomo Business, NTT Docomo and au (KDDI). Pin -isp-ntt_docomo_business, -isp-ntt_docomo, -isp-au_one_net when an account or an app should look like it lives on one network, and keep that choice constant for the life of the account.
Can I get a mobile exit in Fukuoka or Kyoto?
Yes: both are among the 9 Japanese cities in the catalog. Add -region-fukuoka-city-fukuoka to the username (or -region-kyoto-city-kyoto); a country-level username rotates across every city.
How much do Japan mobile proxies cost?
The same as every country on QuanticData: $5 for 1 GB, $20 for 5 GB, $35 for 10 GB, $75 for 25 GB, $250 for 100 GB and $1,150 for 500 GB ($2.30/GB), one-off packs valid 90 days, no port fee. On 30 October 2026 Oxylabs listed $7.5/GB on a $30 a month plan and IPRoyal $6.80/GB for 2 GB; Bright Data publishes no mobile price.
Mobile or residential proxies for Japanese targets?
Residential at $1.00/GB when the site checks the origin but not the device, which is most scraping and verification work. Mobile when the account or the app expects a phone, or when residential exits are already being refused. Start with residential, measure a block, move up.
