TOKYO (AP) — On national disaster prevention day, Japan’s government is urging people to stock up on toilet paper, because more than 40 percent of the nation’s supply comes from a high-risk earthquake zone.

The Trade and Industry Ministry is promoting specialty toilet paper for emergency use, marking Monday’s national disaster prevention day. Officials say people immediately think of food and water as relief goods, but easily forget toilet paper.

Government and industry officials said 41 percent of the country’s toilet paper supply comes from Shizuoka, central Japan, one of Japan’s most earthquake-prone areas. They warned of a toilet paper shortage crisis for about a month if the area is hit by an imminent Tokai mega-quake, a lesson learned from the deadly March 2011 disasters in northern Japan.
