Inside the nuclear bomb shelter in Japan

The need to build nuclear shelters and buy radioactive air purifiers in Japan increased because people feared Korea could launch missiles with ammunition containing poison.

Seiichiro Nishimoto, CEO of Shelter, wears a gas mask in the room simulating a nuclear shelter built in the basement of his home in Osaka, western Japan.

Nishimoto's company, which provides underground bomb shelter services to avoid nuclear bombs, said it received only eight orders in April alone.This figure is higher than normal when the company only receives 6 orders per year, Reuters reported.

"Building a nuclear shelter is costly and time-consuming, but in this tense atmosphere, everyone feels a need to have a plan to prevent all incidents," Oribe said. His company officer went to survey their house to build the tunnel as soon as possible.

Customers can request to build their own design basement such as blue wall paint and tropical-themed wallpaper as shown.

The basement is solid, airtight, and equipped with many machines and equipment.

In addition to air purifiers that help prevent radiation, radiometers, gas masks, an escape route, even television, along with many other supplies for emergency situations.

The room is believed to be able to withstand the explosive pressure of an atomic bomb capable of destroying the same type that the US used to throw at Hiroshima during World War II, as long as the bomb fell apart from 660m or more.

Japanese people have a basis of fear because last month, three Korean missiles fell into an exclusive economic zone about 300-350km from Aki's coast of Japan.On April 23, the North threatened to be ready to sink the US aircraft carrier to prove its military strength.
