Some reached out to Nao Engineering, which has been selling its Crisis-1 shelters since December 2021, but saw a surge in inquiries after Russia’s invasion of Ukraine in February.
Even after more than 70 years, memories persist in Japan of intense bombing during World War II, including the only atomic detonations in combat.
And the nuclear spectre revived recently, after Russian President Vladimir Putin threatened to use “all means” in his nation’s defence.
In Asia, concerns persist that China could try to seize the self-governed island of Taiwan, which it claims as its own.
The year’s most active threat to the Japanese archipelago has been North Korea, which launched dozens of missiles and is said to be preparing for its first nuclear test since 2017.
One of its projectiles sailed over Japan in October, for the first time in five years. And the following month an intercontinental ballistic missile (ICBM) landed just 200km from the northwestern coast.
Nao’s shelters, about the size of a large walk-in closet, are made of iron, with lead plating to withstand all but a direct hit from a missile or nuclear blast, while an Israeli-made filtration system will keep out radiation or dangerous gas.
