Host your AI workloads close to Japanese and Korean users
Most AI products today are an app that calls a model API. That app needs a reliable server, a stable IP and a location near its users. That is what these servers are for.
AI chatbots and assistants
Host web chat apps, customer support assistants and internal tools that call model APIs.
Telegram and Discord AI bots
Keep your bots online 24/7 on a VPS with a fixed Japanese or Korean IP.
AI agents and automation
Run agents, schedulers, workflow tools and background workers that call AI APIs around the clock.
RAG and vector-search backends
Host your API, vector database and document pipeline next to your app.
AI SaaS for Japan and Korea
Serve your AI product to Japanese and Korean customers from a local server and a local IP.
Calls to AI model APIs
Call OpenAI, Anthropic, Google Gemini and similar APIs from Japan or Korea, both supported regions.
Call AI APIs from Japan or Korea
Japan and South Korea are supported regions for the major AI model APIs, such as OpenAI, Anthropic and Google Gemini. A JUSTG VPS in Tokyo or Seoul gives your application a native Japanese or Korean IP to make those API calls from, and keeps that IP stable over time.
A stable IP is useful when you allowlist your server in your own firewall or partner systems, when you want consistent behaviour across sessions, and when your customers expect their data to be processed by a server in their country.
You remain responsible for following each AI provider's terms of use and region policies. JUSTG provides the server and the IP; it does not guarantee access to any third-party service.
Unlock test: ChatGPT, Claude and Gemini
Yes: native Japanese and Korean IPs on JUSTG Tokyo and Seoul servers unlock ChatGPT, Claude and Gemini. The IPs are genuinely in Japan and Korea, so these AI services treat your server as a Japanese or Korean user. In the same test, Netflix and Disney+ also worked from both locations.
| Service | Tokyo | Seoul |
|---|---|---|
| ChatGPT | ✓ | ✓ |
| Claude | ✓ | ✓ |
| Gemini | ✓ | ✓ |
| Netflix | ✓ | ✓ |
| Disney+ | ✓ | ✓ |
Tested by JUSTG in October 2026 on Tokyo and Seoul cloud VPS and dedicated servers. Third-party services may change their policies. Additional IPs can be purchased anytime via the Upgrade options on your service page.
CPU servers: for AI apps, APIs and agents, not model training
To be clear: JUSTG cloud VPS and dedicated servers in Tokyo and Seoul are CPU servers without GPUs. They are a good fit for:
- Web apps, bots and APIs that send requests to hosted AI models
- Agents, schedulers, queues and automation workers
- Databases, vector search, caches and document processing
- Reverse proxies, API gateways and the backend of an AI SaaS
They are not intended for training models or for GPU inference. If you need a GPU, use a GPU provider for the model and a JUSTG server for the app around it.
Which plan fits your AI project?
Plans are the same in Tokyo and Seoul. Every plan includes 1 native IPv4, free IPv6 and a 500 Mbps port. Treat the suggestions as a starting point and upgrade from the client area as you grow.

How to size a VPS for an AI app
When the model runs at the API provider, your server mostly waits on network calls, so it needs far fewer resources than people expect. Memory grows with what you keep on the server: databases, vector indexes, caches and the number of worker processes.
- Bots and webhooks: 512 MB to 1 GB is often enough for a single bot or a small webhook service.
- Chat apps and small SaaS: 2 to 4 GB for a web app, a database and a reverse proxy on one VPS.
- RAG and agents: 8 to 16 GB when you add a vector database, document processing and several agents or workers.
- Larger platforms: 24 GB, or a dedicated server, for many services on one machine or larger indexes.
Need more? JUSTG dedicated servers in Tokyo and Seoul go up to 512 GB of RAM. See Tokyo dedicated servers and Seoul dedicated servers, or open a ticket to request a test server before you buy.
Tokyo or Seoul for your AI server?
Put the server where your users and your data are. Choose Tokyo (Japan VPS) for Japanese customers and a native Japanese IP, or Seoul (Korea VPS) for Korean customers and a native Korean IP. Both run on Asia-optimized routes.
If your needs change, a cloud VPS can move between Tokyo, Seoul and Moscow from the client area once every 30 days. You get a new IP and the old VPS is deleted, so back up your data and update any IP allowlists first.
What every JUSTG AI VPS includes
- KVM virtualization with full root or administrator access
- Linux or Windows Server, and a VNC console in the client area
- 1 native Japanese or Korean IPv4 plus free IPv6
- 500 Mbps port on Asia-optimized routes, 500 GB to 6 TB of monthly traffic
- Automatic deployment after payment
- 24/7 support by ticket in English, Chinese and Russian
- Payment by credit card (via Stripe), Alipay, UnionPay card, PayPal, USDT (crypto) or bank transfer, in USD or HKD
