RadoNet Japan Yokohama Nuro Review: Native IP Performance Test

Looking for a reliable landing server in Japan? This RadoNet Yokohama Nuro package offers native residential IP with solid streaming unlock capabilities, though the routing through KDDI means you'll want to manage your expectations on latency to mainland China.

What You're Getting

RadoNet's NURO M Package runs $50/month for 2 cores, 4GB RAM, 20GB SSD storage, and 10TB bidirectional bandwidth capped at 300Mbps. The provider launched in 2022 as a UK-registered operation focusing on Japan and Hong Kong KVM VPS/VDS solutions. They accept Alipay, credit cards, and cryptocurrency (with processing fees), though residential IP services don't come with refunds.

Testing IP: 118.238.9.2

Performance Breakdown

The disk I/O looks healthy. Mixed read/write tests hit 500MB/s on 4k blocks and peaked around 2GB/s on larger blocks - perfectly adequate for typical workloads.

Network speeds through iperf3 showed consistent 230-290 Mbps uploads across global endpoints. Downloads varied more widely - London and NYC both pulled around 120 Mbps, while Singapore managed 133 Mbps. The Los Angeles connection showed some instability with receive speeds dropping to 44 Mbps on IPv6.

The CPU (AMD EPYC 7K62) scored 1385 single-core and 2432 multi-core on Geekbench 6. Not setting any records, but sufficient for proxy and automation tasks.

The Routing Reality

Here's where things get interesting. All three major Chinese carriers route through KDDI, which sounds good on paper - except everyone else had the same idea.

China Telecom paths through multiple KDDI hops in Tokyo before hitting CHINANET-BB in Guangzhou at 150ms. Beijing endpoints showed 180-380ms depending on packet routing.

China Unicom takes a similar KDDI path before connecting through the CU169 backbone. Tokyo to Beijing measured 84-88ms initially, but end-to-end latencies climbed to 220+ ms.

China Mobile routes through JPIX and CMI-INT with the cleanest path - 51ms to Beijing's CMI gateway, though final endpoint latencies still hit 56-77ms.

The speedtest results tell the real story. China Telecom nodes showed severe download throttling (0.2-2.6 Mbps) with better upload performance. China Unicom Chengdu managed 312 Mbps upload but failed completely on several download tests. Anyone hoping KDDI's lower traffic would mean direct China connectivity should adjust those expectations.

IP Quality Assessment

Both IPv4 and IPv6 present as native residential IPs from Sony Network Communications (AS2527). The IPv4 scored 39/100 on SCAMALYTICS (medium risk) while most other databases flagged it as low-risk residential. IPv6 tested even cleaner with consistent low-risk scores across all databases.

One database (ipdata) flagged the IPv4 as a proxy, but this appears to be a false positive given the consensus from other sources. Port 25 is blocked on both protocols - standard for residential connections preventing spam relay.

Streaming and Service Access

The unlock capabilities are genuinely impressive. On IPv4, everything worked: Netflix (Tokyo CDN via Akari Networks), Disney+, Amazon Prime Video, Spotify, ChatGPT, and Google Gemini all recognized the connection as Japanese residential.

Japanese domestic services unlocked completely - DMM, Abema TV, Niconico, U-NEXT, Hulu Japan, and even region-locked games like Kancolle and Pretty Derby.

IPv6 showed more limitations. While Netflix, YouTube Premium, and Spotify worked fine, ChatGPT failed, Claude blocked access, and Amazon Prime Video doesn't support IPv6 testing. Many Japanese domestic services (DMM, Abema, Niconico) don't offer IPv6 support at all, so you'll rely on IPv4 for most applications.

Compared to previous reviews, this node gained Spotify unlock but lost Claude access. The streaming unlock uses DNS for Disney+ and Netflix (expected for residential IPs that may rotate), while services like Prime Video and Spotify confirm native detection.

Cost Considerations

At $50/month, you're paying for the residential IP premium. IP changes cost $5 each, so factor that in if you need fresh addresses. With 10TB monthly bandwidth, heavy users might find better value in RadoNet's UCOM packages depending on their traffic patterns.

Remember to enable BBR before running speed tests - the default TCP congestion control won't maximize that 300 Mbps connection.

Bottom Line

This Nuro package delivers where it matters most: legitimate residential IP detection and comprehensive streaming unlocks. The KDDI routing means mainland China connections won't be as snappy as direct peers, but the IP quality and service compatibility make it solid for landing server applications, streaming proxy setups, or automation that requires residential trust.

For users prioritizing unlock capabilities over raw China connectivity speed, 👉 RadoNet's Yokohama Nuro infrastructure provides the residential IP authenticity that premium applications demand. Just set realistic expectations about those China Telecom and Unicom latencies.
