We’re currently applying to list our project on platforms like Flippa, but direct contact is welcome and encouraged for those who are seriously interested.
Sumaiina is a peer-to-peer real estate platform from Japan focused on matching vacant houses and traditional properties with buyers and renters — enhanced by original anime-style mascots, creative storytelling, and VR content.
Think: Airbnb meets manga meets regional revitalization.
