AcckCloud Japan VPS Review: IIJ Direct Routes, 1Gbps Bandwidth, Netflix & ChatGPT Unlocked

Looking for a reliable Japan VPS with direct connectivity to China and solid streaming capabilities? This hands-on review examines AcckCloud's Tokyo datacenter offering—featuring premium IIJ routing, triple-ISP direct connections, and surprisingly affordable monthly pricing starting at around $2 USD.

Provider Background

AcckCloud is a China-based hosting provider established in 2024, offering VPS and dedicated servers across Hong Kong, Japan, and Taiwan. Their service interface bears a striking resemblance to certain well-known panels, but the real question is: does the performance match the familiar look? Today we're putting their Japan IIJ route VPS through comprehensive testing.

Network Infrastructure Overview

AcckCloud operates its own ASN (AS401615) with upstream connectivity through BACK WAVES. The network stack includes IIJ, GSL, PCCW, CDN77, JPNAP, and EIE providers. DNS successfully unlocks Japanese streaming services, and all three major Chinese carriers (China Telecom, China Unicom, China Mobile) route directly through IIJ—a premium configuration that typically delivers low latency and stable connections to mainland China.

For international businesses or content creators targeting both Asian and global audiences, this multi-upstream approach provides excellent redundancy. 👉 Experience premium Asia-Pacific connectivity with AcckCloud's optimized network infrastructure—ideal for applications requiring consistent performance across regions.

System Specifications

The test instance runs on Intel Xeon Gold 6133 processors at 2.50GHz with KVM virtualization. The setup includes:

• CPU: 1 core @ 2494 MHz (x86_64 architecture)

• CPU Cache: 16384 KB with AES-NI and VM-x/AMD-V enabled

• Operating System: Debian GNU/Linux 12 (64-bit)

• Kernel: 6.1.0-13-cloud-amd64

• Storage: 4.9 GB total capacity

• RAM: 473 MB total

• Network: BBR congestion control with fq queueing

• Location: Tokyo, Japan (AS401615)

Disk I/O performance averaged 105 MB/s across three consecutive tests—adequate for general workloads though not exceptional. The system maintains solid uptime with load averages hovering around 0.09.

Streaming & Service Unlocking

IPv4 Capabilities

The DNS unlocking configuration successfully accesses:

• Dazn: DNS unlock (Singapore region)

• TikTok: Native unlock (Seychelles region)

• Disney+: DNS unlock (Japan region)

• Netflix: DNS unlock (Japan region, CDN associated with Cox Communications in Tokyo)

• Amazon Prime Video: Native unlock (Japan region)

• TVBAnywhere+: Native unlock

• iQyi Overseas: Native unlock (Japan)

• ChatGPT: DNS unlock (Japan region)

• Google Gemini: Native unlock (China region)

YouTube Premium shows as unlocked for China region, while Spotify registration works with Seychelles region. Steam transactions process in USD. Some services like Instagram Licensed Audio failed during testing.

IPv6 Performance

IPv6 connectivity showed mixed results with several streaming services experiencing network connection failures, though YouTube Premium achieved native Japan region unlock. This suggests IPv4 remains the more reliable option for media streaming applications.

Latency & Network Performance

Domestic China Connectivity

Testing reveals competitive latency figures to major Chinese cities:

• Average mainland China latency ranges from 70-160ms depending on carrier and region

• China Telecom routes show 73-110ms to Shanghai and Hangzhou

• China Unicom connections average 94-121ms to Shanghai

• China Mobile exhibits slightly higher latency at 105-165ms

Packet loss remained minimal during testing periods, with stable three-ISP routing through IIJ backbone infrastructure.

Speed Test Results

Domestic China (Three Major Carriers):

• Hangzhou CM: 464 Mbps download

• Shanghai CU: 397 Mbps download

• Suzhou CT: 490 Mbps download, 422 Mbps upload

• Hangzhou CT: 492 Mbps download

Global Endpoints:

• Singapore: 491 Mbps download, 444 Mbps upload (70ms)

• Los Angeles: 487 Mbps download, 413 Mbps upload (114ms)

• London: 467 Mbps download, 313 Mbps upload (218ms)

• France: 269 Mbps download, 271 Mbps upload (247ms)

The 1Gbps port delivers consistent performance across most routes, though some carrier combinations show occasional variability.

Routing Analysis

Return Path Routing

China Telecom: Traffic routes through IIJ Tokyo infrastructure to China Telecom's international gateway (203.215.236.65), then enters mainland via Hong Kong before reaching Shanghai/Guangzhou endpoints. Typical hop count: 13-17 hops with 110-160ms latency.

China Unicom: Routes traverse IIJ to CU169-BACKBONE via Osaka/Tokyo interconnection points. Both standard routes and AS9929 (CUII premium network) show efficient 11-14 hop paths with 74-106ms latency.

China Mobile: Connections transit through IIJ then CMI (China Mobile International) infrastructure in Hong Kong before entering CMNET mainland network. Path length varies from 9-17 hops with 61-145ms latency depending on destination.

CERNET (Education Network): Academic traffic routes via China Unicom's CU169 backbone, entering CERNET through Beijing nodes before reaching regional endpoints like Hangzhou. Approximately 14-17 hops with 74-125ms latency.

IPv6 Routing Observations

IPv6 paths show greater variability by destination and carrier. Shanghai routes demonstrate 7-11 hop efficiency, while some destinations experience higher latency due to suboptimal peering arrangements. IPv6 deployment appears less mature compared to IPv4 infrastructure—users requiring IPv6 should conduct region-specific testing.

Summary

AcckCloud's Japan IIJ VPS delivers solid fundamentals for users prioritizing connectivity to mainland China alongside global streaming access. The triple-ISP direct routing through premium IIJ infrastructure provides consistent low-latency performance to Chinese cities, while DNS unlocking successfully accesses major platforms including Netflix and ChatGPT.

Standout features include competitive pricing, genuine IIJ backbone connectivity, and successful unlocking of popular streaming services. Areas for improvement include IPv6 stability and disk I/O performance for storage-intensive workloads.
