How it works
Unhurried, never vague.
SumiNavi supports the information and communication around a purchase decision. We do not broker property, act in a contract, or provide legal or tax advice.
Prepare the conversation
Share preferred areas, budget, purpose, timing, and any listings already found. An incomplete brief is welcome.
Create a decision frame
We organize priorities and questions in English and Japanese so different properties can be compared on the same terms.
Verify third-party information
We surface price, rights, management, building condition, and handover points for the licensed listing agent to confirm.
Prepare specialist handoffs
Legal, tax, registration, and building inspection questions belong with qualified professionals. We help prepare the brief and documents.
Record the decision
Separate what is confirmed, outstanding, and conditional so the next step remains visible.
Fees & boundaries
Start free. Keep terms visible.
The initial inquiry is free. The proposed commercial model is a support fee equal to 10% of the purchase price, payable only after completion; you may cancel before purchase at any time without a cancellation fee.
Important: because SumiNavi is an individual operator without a real-estate brokerage licence, this success-fee model has not yet been cleared as legally compatible with the intended non-brokerage scope in Japan. Qualified review and final written terms are required before any paid engagement begins.
