A rock from Mars will be showcased at the 2025 Osaka Expo's Japan Pavilion.

Informed sources said the government plans to put on display the Martian meteorite that a Japanese expedition collected from Antarctica in 2000.

An analysis by the National Institute of Polar Research shows that the meteorite was likely ejected from Mars about 10 million years ago and reached Earth several tens of thousands of years ago.

Officials said it is one of the largest meteorites with links to Mars that has been collected on Earth.

The rock will be displayed to the public for the first time.

The world exposition is scheduled to run from April to October next year in Osaka, western Japan.
