When was the last time Mount Fuji erupted?

But that doesn’t mean it will never happen again. The tallest peak in Japan, Fuji used to erupt roughly every 30 years before it went dormant in the 18th century. Japanese officials want to prepare the populace in case the volcano ever decides to reawaken.

In light of Volcanic Disaster Preparedness Day, the country released AI-generated videos depicting what would happen to Tokyo, which sits just 60 miles away, if Fuji did blow its top. The videos show Tokyo being shrouded in volcanic ash within hours, halting transportation and causing widespread food and power supply issues. It also highlights the potential for long-term respiratory problems.

“The simulation is designed to equip residents with accurate knowledge and preparedness measures they can take in case of an emergency,” said a statement from Tokyo’s government. Officials reiterated that there are no current signs that Fuji is planning to erupt. They just want people to be prepared by showing them what could happen. “Nature’s power is so great that maybe it’s better if it scares us a little,” said one resident, who shared that the video encouraged her to purchase emergency supplies.
