Magnetic compasses

Magnetic compass has its root in "zhi nan yu (literally 'south-pointing fish')", a fish-shaped magnet that was invented in the Song era in China. Zhi nan yu was brought into Europe, and was evolved into "magnetic compass", which was later called one of the three most important inventions in the Renaissance. Magnetic compass came into full bloom during the Great Navigation Age, and made great contribution to civilization. It is no exaggeration to say that magnetic compass changed the subsequent world history.

Nunotani tackled the production of nautical magnetic compasses for the first time in Japan in 1892, and has been promoting studies and improvements over the 120 years since then, in order to meet requests from customers.
