This week the Tokyo Metropolitan Government showed videos made with computers and AI for Volcanic Disaster Preparedness Day. The videos displayed what could happen if Mount Fuji erupted. The volcano is about 100 kilometers from Tokyo and last erupted in 1707. The video showed ash covering the city quickly, stopping trains and buses, damaging food and power, and making breathing dangerous. Officials said the videos were made to prepare 37 million people living in the Tokyo area for possible disasters. They also said there are no signs of an eruption now. Japan is often hit by disasters such as earthquakes, typhoons, and volcanoes, which makes planning important.

The government explained that the video was not a warning but a way to teach people how to prepare. It showed advice such as keeping food and medicine at home. A university expert said the simulation was based on years of study and not on current danger. Some people said the images made them worried. Disaster experts added that videos like this can help people stay ready even if they cause some fear. Japan is known for making strong plans to protect people from natural disasters.
