Japan: High Sales of Nuclear Shelters as North Korea Tension Mounts

Nuclear shelters and radiation-blocking and chemical gas air filters have seen higher sales in recent weeks as North Korea continues its nuclear program, including nuclear and missile tests, and America and China take a tougher stance on the nation's military activities. Some stores have sold out.

Three North Korean missiles landed in Japan's waters, 300-350 kilometres from shore, last month.

Japan is also urging local governments to hold evacuation drills.
