A sharp drop in temperatures is anticipated across mainland Japan on the 29th and 30th, according to recent weather forecasts. The significant cooling is due to an influx of cold air mass, a "cold surge", expected to blanket the majority of the country. Residents and visitors are warned to prepare adequately for the plummeting temperatures, which could impact transportation, daily activities, and health, particularly among the elderly and vulnerable.

In Japan, weather reports are taken very seriously due to the country's diverse climates and susceptibility to natural disasters. Upon such warnings, people prepare by ensuring their homes are well-heated, wearing layers of clothing, and taking care of the elderly and children who are more vulnerable to sudden temperature changes. It also affects various sectors - agriculture, fishing, construction, and more.

Similar to Japan, in the United States and the European Union, severe weather warnings also prompt immediate action with people preparing in advance to limit the impact. Especially in countries where an extreme weather change might lead to intense scenarios - like a snowstorm in the Northern states of the US or Northern European countries - preparations can be extensive and involve governmental bodies.
