Car Antenna (Pillar Type）

The rod antenna for transistor radios, hit products at that time, was what propelled Yokowo Manufacturing Co., Ltd. to the forefront. Yokowoʼs high-quality antennas with their smooth extendibility based upon precision pipe processing technologies garnered recognition from electronics manufacturers. In this way, antenna technologies became a core business for the Company.

As the founder of Yokowo Manufacturing Co., Ltd., the predecessor of YOKOWO CO.,

medical equipment.

LTD., Chutaro Yokoo (1894 to 1977) rened his skills as a craftsman producing precision

pipes used in pocket watch hinges. When wristwatches entered the mainstream, he

invented the spring bar. This is a belt-attachment component comprising a spring

inserted into an ultra-thin pipe, so it can expand at both ends. This landmark invention

became widely adopted overseas, capturing the worldʼs largest market share. This was

the starting point of "technical Yokowo" that exists to this day.

Everything Started with Pipes

After having nished his apprenticeship in 1922, Chutaro Yokoo decided to go out on his own and start a business, opening the Seirinsha bicycle shop the next year. This was destroyed on the day of opening by the Great Kanto Earthquake, but reopened just one month later.

In 1926, using the skills he had acquired over 15 years as a craftsman, he opened a precision pipe processing factory in Mukojima, Tokyo.

Thus was born Yokowo Manufacturing Co., Ltd., the predecessor of YOKOWO CO., LTD.

Circuit Testing Connector Business

1979～

Specications required for probes and sockets for semiconductor testing are becoming more

and more exacting, due to the miniaturization and increased performance of semiconductors. Yokowo started its circuit testing connector business

in 1979, providing the world with semiconductor testing jigs developed using microwave technology, in addition to its world-class micro precision processing technologies.
