We began manufacturing steel record needles in 1949 and modern diamond tipped styli in 1966. Our factory headquarters is located in Hamasaka, situated on the Sea of Japan in the northern part of Hyogo prefecture, approximately 500km from Tokyo.
In winter Hamasaka experiences heavy snowfall and long ago we were unable to travel even to the next town, being cut off by the many mountain passes. Therefore it was necessary to design, fabricate, and repair all production facilities and required equipment, such as our custom jigs, by ourselves. Even today, with advances in modern transportation infrastructure, three to four hours are required to reach a major city. In other words, enduring the hardship and inconvenience of geographic isolation has given us the technological strength to be self-reliant. As the maxim goes, “Necessity is the mother of invention.”
We manufacture approximately 2,200 different models of record styli, and each stylus is hand-assembled. Today the JICO name is well known by audiophiles around the world as the maker of the Super Analog Stylus, a rare needle known for both superb quality and excellent fidelity.
