## Resource

Want to buy an akiya in Japan but the idea of earthquakes keeping you up at night? We get it. Japan shakes, so we made a tool to help you figure out where to look. This week, Joey and Take catch up with university friend Keita, the geospatial software engineer who built AkiyaMart's new earthquake overlay filter. He explains how it works, why Shindo (felt intensity) matters more than magnitude for property buyers, and the key limitations of 100–120 years of historical data. Follow us on Instagram [https://www.instagram.com/akiyamart] and YouTube [https://www.youtube.com/@AkiyaMa]! Buying a House in Japan is a production of AkiyaMart.
