YKT Corporation, established in 1924, acquired 100% of the shares of Sun Instruments in 2002. As a specialized trading company, YKT has long supported Japan's manufacturing industry by importing high-performance machine tools and industrial machinery from Europe and the United States, while exporting advanced electronic manufacturing equipment.
YKT imports a wide range of high-precision machinery and inspection equipment, including grinding machines and laser processing systems for producing high-quality cutting tools and components, as well as coordinate measuring machines and various testing instruments.
The company’s headquarters is located directly in front of Yoyogi-Hachiman Station in Tokyo. Domestically, YKT operates six offices across Japan, and internationally, it maintains offices in China, Taiwan, Thailand, and Germany.
Our office is located about a 5-minute walk from the nearest station, JR Gotanda Station. It is in a highly convenient location—just two stops from Shinagawa Station and three stops from Shibuya Station. Nearby, the Meguro River attracts many visitors during the cherry blossom season. For about two kilometers from near the office toward Ebisu Station, the river is lined with cherry trees, creating a tunnel of blossoms that becomes a popular and beautiful walking path.
Before delivering products to our customers, we perform operational checks on applicable items. For laser inspection, we conduct the necessary measurements using equipment such as power meters, beam profilers, optical spectrum analyzers, autocorrelators, photodetectors, and spectrometers.
