Japan just buried a tiny reactor called Yoroi that powers towns for 10 years

Japan has developed a groundbreaking nuclear innovation called the Yoroi Reactor — a microreactor no larger than a shipping container.

Designed for isolated communities and disaster zones, this buried reactor provides clean energy for a full decade without refueling.

Unlike traditional nuclear power plants, the Yoroi has no towers, no on-site staff, and no risk of meltdown.

It uses molten salt cooling and low-enriched uranium in a sealed unit, making it safe even during earthquakes.

Two Yoroi Reactors are already powering remote towns in Hokkaido, Japan, replacing dirty diesel generators with zero-emission energy.

The system is completely passive — it shuts down automatically if anything goes wrong.

By 2030, Japan plans to install 50 more across the country. This might be the boldest nuclear experiment the world has ever seen.
