Overall ranking
Sample2LDK in Funabashi, Chiba
8 min walk to station / Pre-owned condo
5% below market with low flood risk. A bit of a walk to the station, though.
Good space for the price. But it is an 11-minute walk to the station.
3LDK in Hachioji, Tokyo ・ 11 min walk / Pre-owned condo
Close to the station with low disaster risk. The lot is on the small side.
2LDK in Kawaguchi, Saitama ・ 6 min walk / Pre-owned house
New and in good condition. The price is about market level.
1LDK in Sagamihara, Kanagawa ・ 9 min walk / New house

About
Sumilca (すみるか in Japanese, pronounced “su-mi-ru-ka”) is a second-opinion service for people buying a home in Japan. It gathers condos and houses listed across multiple real-estate sites, scores them on the same three measures — price, commute time, and disaster risk — and ranks them for your conditions.
It takes a third-party view, separate from sellers, so you can check the numbers and sources behind why a candidate stays on your list or drops off.
You can start for free with no name or email. Coverage currently centers on the Kanto (Greater Tokyo) region and is expanding.
You can change conditions as many times as you like. Start by seeing how the candidates differ.
