Meteorologists are sounding the alarm for a three-day weekend across Japan, with heavy rainfall predicted from West to East. The unwelcome downpour is forecasted during a national holiday period, potentially imposing travel disruptions and flood risks. Residents are being urged to stay vigilant, prepare for potential evacuations, and keep updated with local weather news and advisories.

Weather predictions, especially concerning rainfall and typhoons, are taken seriously in Japan due to the country's geography that makes it prone to natural disasters. Japanese people are typically well-prepared and responsive to such updates. Moreover, national holidays like the upcoming 3-day weekend are treasured opportunities for trips and family gatherings, hence weather disruptions could significantly affect people's plans.

Similar to Japan, in the US and EU, severe weather warnings are given high priority. Weather services provide up-to-date information and advisories to the public for preparation and necessary actions such as evacuations if needed. However, the denseness of population and infrastructure in many parts of Japan might make the effects of severe weather more impactful than those in larger, less populated areas of the US or EU.
