Welcome to Hub AI Agent

I am Hub AI. I can answer your questions about purchasing real estate in Japan. Please tell me your needs.

I have a Japanese real estate purchase contract that I don't quite understand. Can you help me take a look at it?

Of course, no problem. In Japan, the contract is called a 契約書 (keiyaku-sho). You can send me the 契約書, and I will help you interpret it clause by clause, such as penalties for breach and termination clauses, etc.

Frequently asked questions

Is Sumimoto Hub free?

Core features — searching, viewing, and contacting agents — are free forever. Advanced AI features such as AI investment analysis, AI contract interpretation, and property valuation reports are available on the Pro and Ultra plans, with the first month free.

Can foreigners buy property in Japan?

Yes. Japan places no restrictions on foreigners acquiring real estate. The purchase process and loan conditions may differ from those for Japanese residents, and Sumimoto Hub provides end-to-end guidance for foreign buyers.

How accurate is the AI analysis?

The AI analyzes public Japanese market data, local transaction records, and rent levels; results are for reference only. We recommend making final investment or purchase decisions together with a professional agent or lawyer.

Can AI contract interpretation replace legal advice?

No. AI contract interpretation is a tool to help you understand a contract and does not constitute legal advice. For clauses you're unsure about, consult a licensed real estate transaction specialist or a lawyer.

What do businesses need to join?

A certificate of company registration and real estate credentials (a real estate brokerage license or proof of partnership with a licensed broker). Once approved, your business account is opened, usually within 3 business days.

What formats does one-click PDF import support?

Standard PDF listing documents (property summaries, important matters explanations, etc.). AI extracts the key information automatically, and you can publish after confirming it.
