🇯🇵 Japan Proxy Guide

Build Your Own Japanese Mobile Proxy Farm (DIY)

Q: Which Japanese carrier offers the best value for proxy farms?

Rakuten Mobile is highly recommended because they offer genuinely unlimited data plans at a very low monthly cost (around ¥3,278/month), and they operate on compatible LTE Band 3 and 5G n77.

Q: Can I use tourist prepaid SIMs for my Japan proxy setup?

No, tourist SIMs are typically data-only, non-reloadable, and do not allow IP rotation or network reconnection. You should use standard post-paid or pre-paid contract SIM cards.

Ditch expensive Japan proxy rentals. Deploy dedicated 4G/LTE & 5G proxy servers using local Japanese SIM cards and XProxy hardware with unlimited bandwidth.

Carrier Compatibility in Japan

XProxy hardware and software are fully compatible with major cellular networks in Japan. Here are the verified bands and integration status.

Carrier	Network Type	LTE / 5G Bands	XProxy Compatibility	Operational Notes
NTT Docomo	4G/5G	B1, B3, B19, B21, B28, n78, n79	Very Good	Requires checking LTE bands. Perfect with XProxy modems supporting Band 19. Has strict IMEI blocking on data-only SIMs.
SoftBank	4G/5G	B1, B3, B8, B28, n77	Excellent	Easiest APN setup. Broad compatibility with standard XProxy dongle configurations. Highly recommended for DIY due to lenient IMEI restrictions.
au (KDDI)	4G/5G	B1, B3, B18, B26, B28, n77, n78	Very Good	Highly reliable network. au SIMs work great in urban centers.
Rakuten Mobile	4G/5G	B3, n77	Excellent	Best cost per GB. Works exceptionally well on 5G with Rakuten band 3 / n77.

Pro DIY & Self-Build Tips for Japan

Unlock the highest quality connections and bypass carrier restrictions with these market-specific optimization tricks.

TIP 1 TCP OS Fingerprint Spoofing

Japanese anti-bot systems (like Yahoo JP or Mercari) inspect TCP packet headers (MTU/MSS & TCP Window Size) to spot proxy tunnels. XProxy’s OS Spoofing automatically aligns these network values to match real iOS/Android devices perfectly.

TIP 2 Vless & Trojan Protocols for Stealth

Bypass strict security filters on Japanese e-commerce or ticketing platforms. Use XProxy to route traffic via Vless or Trojan protocols instead of standard SOCKS5 to hide proxy signatures and maintain high-quality connections.

TIP 3 Lock Rakuten to Band 3

Rakuten Mobile uses au (KDDI) roaming where Rakuten’s own network is weak. However, roaming data is capped. Lock your XProxy modems to Band 3 (1800MHz) to force connections onto Rakuten’s native unlimited network.
