Osaka sits around Osaka Bay in Japan’s Kansai region, where the tsuyu rain front in June and July and the typhoon season from August through October together produce most of the year’s rainfall.
Japan’s third-largest city sits at the mouth of the Yodo River on Osaka Bay, a low-lying delta setting that has driven major flood-control investment over the past century. The dense, low-lying urban area around the bay means heavy rain can pool quickly in built-up districts, and radar is widely used alongside the Japan Meteorological Agency’s official warnings to track approaching rain bands in real time.
