Hi Product Hunt! I'm the founder of SUMIMOTO. Buying property in Japan as a non-Japanese speaker is harder than it should be. Listings live on portals like SUUMO that assume fluent Japanese, agencies rarely service overseas buyers in their own language, and once you factor in cross-border payments, foreign-resident mortgages, and tax rules, most people simply give up — or overpay through opaque middlemen. We built SUMIMOTO to fix that. It lets Chinese-speaking buyers search, evaluate, and inquire about Japanese real estate entirely in their own language, and connects them to licensed Japanese agencies. Tell it your budget, purpose, and area, and AI returns a ranked shortlist in about 30 seconds — with the data sources behind every recommendation shown, not hidden. This is our v1.0, focused on the brokerage experience. Chat, reviews, and full multilingual UI are on the roadmap. We'd love your honest feedback — especially from anyone who has tried to buy or rent across borders. What would make this genuinely useful for you?
