DMIT has recently upgraded its Japan T1 series VPS to the GSL network and launched promotional discounts, including 10% off for monthly billing and 30% off for quarterly or longer billing cycles. Although the T1 series is positioned as an international route (not optimized specifically for mainland China), users on China Unicom and China Mobile networks experience excellent real-world performance, with low latency and smooth connectivity—making it especially suitable for streaming media consumption and lightweight website hosting.
One of the key highlights is DMIT’s updated bandwidth policy: even after monthly traffic is exhausted, the server still retains usable 100Mbps bandwidth, effectively functioning as “pseudo-unlimited traffic,” offering strong value for money.

1. Plan Overview (Japan T1 Datacenter)
| CPU Cores | RAM | Storage | Monthly Traffic | Bandwidth | IPv4/IPv6 | Monthly Price | Quarterly Price | Payment |
|---|---|---|---|---|---|---|---|---|
| 1 Core | 1GB | 20GB SSD | 2TB | 4Gbps | 1 IPv4 / /64 IPv6 | $6.21 (Promo: 2025-TYO-T1-HI-GSL-MONTHLY-10OFF) | $14.49 (Promo: 2025-TYO-T1-HI-GSL-NON-MONTHLY-30OFF) | Buy Link Supports Alipay, WeChat Pay, PayPal |
2. Hardware Performance: Powerful CPU and Excellent Disk Speed
The T1 series is powered by AMD EPYC 7443P processors with a single-core boost frequency of around 2.845GHz. Memory read performance reaches approximately 991MB, with additional virtual memory allocated without consuming disk space, ensuring system stability.
Storage uses SSD, with real-world read/write speeds averaging 1.1GB/s. Overall hardware performance is superior to most VPS offerings in the same price range. The virtualization technology is KVM, providing stability and support for custom kernels and TCP acceleration.
3. Bandwidth & Network Performance: Strong Throughput, Moderate Stability
In testing, the VPS provides a 4Gbps bandwidth port. Local Japanese upload and download speeds exceed 3Gbps. When accessing mainland China, download speeds fluctuate but generally remain around 500Mbps, with a minimum of about 200Mbps:
- Upload Speed:
- China Telecom: ~70Mbps
- China Unicom: ~800Mbps
- China Mobile: ~300Mbps
- Hong Kong / Taiwan / Overseas: ~100–300Mbps
Although upload performance varies, it is sufficient for daily use and small-scale applications.
4. Routing & Latency Analysis: Unicom & Mobile Direct Routing, Telecom Weaker
Average latency in mainland China is around 303ms, indicating a somewhat non-optimized international routing path. However, performance differs by carrier:
- China Telecom: Outbound routes via Europe (Netherlands). Although return traffic uses GSL direct routing, latency remains high.
- China Unicom: Outbound via NTT direct to Japan, return via GSL—overall low latency and stable performance.
- China Mobile: Outbound via AS9808 (CMI) direct routing; return partially via CMI and GSL, offering stable and low latency.
Overall, the T1 series is best suited for China Unicom and China Mobile users.
5. Native IP Streaming Unlock Capability
Testing confirms that the T1 series uses Japanese native IPs, which can successfully unblock:
- Netflix Japan
- TikTok Japan
- Selected Japan-region AI platforms and streaming services
IP quality checks show it is a standard broadcast IP. Port 25 is closed, making it suitable for streaming and moderate workloads.
6. Video Streaming Experience: Over 120K Kbps on Unicom, Smooth 4K Playback
YouTube streaming tests show speeds exceeding 120,000 Kbps on China Unicom, enabling smooth 4K playback. China Mobile is expected to perform similarly, while China Telecom may experience buffering due to longer routing paths.
7. Web Hosting & Extended Use Cases
After installing a basic LNMP stack via the BaoTa panel, the VPS still retains approximately 486MB RAM and 14GB disk space, making it suitable for lightweight website hosting.
With stable routing and effectively “unlimited-like” bandwidth after throttling, it is also suitable for small download sites or file transfer nodes.
FAQ
Q1: Who is the T1 series suitable for?
A: It is recommended for China Unicom and China Mobile users, especially for streaming, lightweight hosting, and access to Japan-based services.
Q2: Does it support Alipay payment?
A: Yes, it supports Alipay, WeChat Pay, and PayPal.
Q3: Is it a China-optimized route?
A: No, it is not a China-optimized line, but Unicom and Mobile benefit from GSL direct routing.
Q4: Is there a traffic limit?
A: Yes, 2TB monthly traffic is included. After exceeding the limit, 100Mbps bandwidth remains available, effectively acting as “pseudo-unlimited traffic.”
Conclusion
Although DMIT’s Japan T1 series is positioned as an international routing product, its powerful hardware, GSL return network, and post-cap bandwidth retention make it highly competitive in its price range.
It is especially suitable for China Unicom and China Mobile users. Combined with strong Japanese native IP unlocking capabilities, it also expands its use cases for streaming and cross-border applications. If you are looking for a cost-effective Japan VPS, this series is worth considering.
