"Please prepare at least three days', and if possible a week's, worth of food, water and emergency toilets." When Japan's disaster minister announced this "urgent request to the public," some people online in Japan asked whether a third world war was coming. So should anyone heading to Japan rethink their trip?
In short, the minister said at an October 30 press conference that it was not based on information predicting a war or disaster. It was a call to prepare for major earthquakes, timed with the new Disaster Management Agency that opened on November 2. This article is based on reports by Yonhap News (November 1), Herald Business and YTN (November 2).

What is new: the Disaster Management Agency, launched November 2
The agency upgrades the Cabinet Office's disaster management division and acts as the control tower for disaster response, from prevention to recovery. The prime minister heads it, and the new post of disaster minister is held concurrently by Koshi Hosono, minister for reconstruction.
Its stated purpose is to prepare for mega-disasters such as a Nankai Trough earthquake and an earthquake directly beneath the Tokyo area. According to YTN, the minister also mentioned an eruption of Mount Fuji and stressed the need for a different level of preparation.
What the "urgent request" says
The request, as reported, is to keep water, food and emergency (portable) toilets for at least three days, and preferably 1 week. YTN also reported a guide of 3 liters of drinking water per person per day.
In an October 26 TV appearance, the minister explained that if more people can support themselves, help can be focused on those who truly need it. Around the same time, the UK government reportedly began a campaign asking people to keep supplies for at least three days, plus a flashlight, power bank, radio and cash.
Why war rumors spread, and what the government said
The phrase "urgent request" combined with stockpiling advice led to speculation about war, a large cyberattack or an imminent major earthquake.
At the October 30 press conference, Minister Hosono said that while some suggested there was information predicting a war or disaster, that was not the case. He described it as a strong reminder to prepare for large disasters that may come in the future.
What it means for travelers to Japan
These reports mention no disaster forecast for a specific date and no new measures on travel or entry. As of checking, the request is advice to people living in Japan about everyday preparedness.
Still, Japan is a country with frequent earthquakes. Even on a short trip, knowing your hotel's emergency exits and evacuation route, and carrying a charged phone and a bottle of water, helps you stay calm if the ground shakes. Check official safety information such as travel advisories from Korea's Ministry of Foreign Affairs before you leave.
