Science Japan’s legendary battleship Yamato recreated on a microscopic scale

At the Yamato Museum Satellite, visitors can now glimpse a version of Japan's storied World War II battleship Yamato recreated on a scale so tiny it defies the naked eye. The model, measuring a mere 0.263 millimetre—one millionth the size of the original—was produced through submicron 3D printing technology. Because of its minuscule dimensions, viewers must peer through a magnifying glass to see it at all. The satellite venue is currently hosting the exhibit while the main Kure Maritime Museum, better known as the Yamato Museum, undergoes renovations scheduled to continue until March 2026. The original Yamato, built at the Kure Naval Arsenal, stretched an imposing 263 metres from bow to stern and stood as a symbol of Japan's naval ambition during the war.

A 1/10 scale model measuring 26.3 meters was previously displayed at the main Yamato Museum. The facility commissioned Castem Co., a precision metal parts manufacturer in Fukuyama in the prefecture, to create the miniature Yamato. The surface of the resin-based model is coated in platinum. It took about three months to recreate details like the main guns, propellers and stern flagpole.
