Are these really 5G Mobile proxies in Japan?

Yes — the exits in this pool announce from the Japan ASNs we list on the country page (NTT Communications (AS2914), KDDI (AS2516)) and route through our Asia edge. You can verify ASN and carrier on every request.

What session lengths can I hold on Japan 5G Mobile?

Per-request rotation is the default. Sticky sessions are supported up to 60 minutes via the X-Squad-Session header. For anything longer, use our ISP pool instead.

Is targeting down to a city available on Japan 5G Mobile?

Yes, via X-Squad-City. Pool depth varies by city — the deepest are Tokyo, Osaka, Kyoto. Smaller cities are served but have thinner concurrency.

Any legal or compliance notes specific to Japan?

Japan has the most permissive training-data legal environment in the G7. Article 30-4 of the Copyright Act (revised 2018) explicitly permits text and data mining of copyrighted works for non-enjoyment purposes, which has been interpreted by the Agency for Cultural Affairs (ACA) to cover AI training. The APPI governs personal data; cross-border transfer requires either equivalent-country status, consent, or equivalent safeguards. There is no general public-figure carve-out in the way US law treats it.

Japanese 5G mobile proxies for advanced cellular AI evaluation

JP 5G: the premier cellular-AI eval surface in APAC

Japanese 5G is operationally more mature than most markets:

All four JP carriers (DoCoMo, KDDI au, SoftBank, Rakuten) have nationwide 5G coverage as of 2026
NR SA (standalone) is live on all four; 5G SA subscriber share is the highest in APAC after Korea
Network slicing is in production use for specific enterprise and content services

This makes JP 5G the right pool for AI evaluation workloads that specifically want to test cellular-5G-anchored behaviour in APAC:

Ultra-low-latency AI path eval. JP 5G to ap-northeast-1 (Tokyo) lands at ~15-50ms p50 — among the shortest cellular-to-cloud paths globally.
5G SA network-slicing eval. Testing whether a model API or content service responds differently when the request arrives over a 5G SA slice vs. an NR-NSA fallback.
Regional 5G-mobile-first service eval. Japan-deployed 5G-first services (XR, AR/VR, specific mobile-AI apps) require actual 5G path for realistic evaluation.

Carrier-level 5G notes

NTT DoCoMo — broadest 5G coverage nationally, strong SA deployment.
KDDI au — early SA pioneer, particularly strong in Kanto and Kansai metros.
SoftBank — strong urban 5G, NSA-heavy in some areas.
Rakuten Mobile — 5G-native architecture, distinct from the incumbents, valuable for eval diversity.

What 5G specifically gives you vs 4G

Lower latency (~30-50% shorter p50)
Higher burst bandwidth (but proxy workloads rarely benefit)
Network slicing visibility where the carrier exposes it
Different congestion behaviour under peak

For AI evaluation, the latency and slicing aspects are usually the point. For other mobile-anchored workloads, 4G is cheaper and functionally equivalent — see JP 4G mobile.

What 5G actually changes

Most "5G proxy" marketing is 4G LTE with a 5G SIM slapped on a non-standalone network. There's a real distinction worth making:

5G NSA (non-standalone). Uses the LTE core with a 5G radio. Latency behaves like 4G. Most "5G" plans in the US, UK, and large parts of Europe are NSA as of early 2026.
5G SA (standalone). Uses the 5G core. Sub-30ms RAN latency is achievable, edge compute integrations are possible, and network slicing is real. Commercial SA coverage is patchy but expanding.

SquadProxy runs both. When you request 5G exit, you can pin to SA where the carrier supports it.

When 5G is the right AI tool

Latency-critical eval. Voice AI, real-time agent eval, and streaming model-response benchmarks where the mobile-path latency matters to the measurement.
IPv6 path testing. A growing fraction of 5G traffic is IPv6-primary. If your eval targets advertise different content or apply different routing on IPv6 (some mobile-first social platforms do), you need a real IPv6 mobile origin.
Mobile-first model agent evaluation. Evaluating how an AI agent behaves on a mobile network-typical path — retries, TCP behaviour, TLS resumption — from within that network.

Where 5G is wrong

SquadProxy collection at any meaningful scale. Mobile bandwidth economics make 5G unviable for TB-scale training-corpus work.
Cost-sensitive long-session eval. 5G sessions cost roughly the same per minute as 4G. The premium goes on latency. If your eval is tolerant of 100–200ms, use 4G or ISP.

Coverage

US — Verizon and T-Mobile 5G SA in major metros. AT&T 5G NSA.
UK — EE 5G SA (where deployed), Vodafone 5G, Three 5G.
Germany — Deutsche Telekom 5G SA, Vodafone DE 5G.
Japan — NTT Docomo 5G SA, KDDI au, SoftBank, Rakuten.
Singapore — Singtel 5G SA, StarHub 5G.

Other markets are 4G-only for now. We'll expand as SA rollouts reach stable commercial coverage.
