The residential quarter of Ota City, Tokyo, is not too far from Kamata Station on the Keikyu Line. There, you will find a tiny metal workshop with six employees. This is Matsuura Machinery Corporation, whose specialty is micromachining. The company is able to cut grooves as narrow as 30 microns into a metal surface. Why is it so particular about micromachining? "In Ota City, we cannot bear to live unless we have something that nobody else can imitate," answered Mr. Takayuki Matsuura, president of Matsuura Machinery. In Ota City, there are roughly 4,700 factories today, approximately 80% of which have only nine or fewer employees each. World-class workshops, though tiny, are growing, intent on furthering their skills.

Komatsu Spring Industrial Co., Ltd. possesses manufacturing technology that enables it to produce microsprings that are thinner than human hair. The company makes springs from wires with a minimum diameter of 30 microns. According to President Setsuko Komatsu, "Competition is always keen, but customers have raised technical standards." She is confident that by constantly trying to work out new techniques, her company will be able to progress further.

Because many of these factories specialize in a particular field, they help one another by jobbing out what they cannot do themselves to others in Ota City. Their favorite joke goes like this: "If you fly a paper airplane off the roof of a building in Kamata, it will return as a real plane." This implies that all metal working functions can be found in this town, including cutting, boring, plating, pressing, grinding, casting/forging, and molding.

To make a huge parabolic antenna roughly four meters in diameter, four people work on a large, round metal plate to shape it into something resembling a dish that is deeper toward the center. This unique skill is known as metal spinning. Kitajima Shibori Seisakusho Co., Ltd., dedicated to metal spinning ever since its founding, is second to none in terms of the specialized skills it possesses. The company's products include sophisticated parts for solid rocket boosters used in launching the H-II rocket. The company's president, Minoru Kitajima, declares, "The craftsman's skill is the sole secret to our survival."

Distinguished skills and craftsmanship that have evolved amid competition are the core of Ota City's industrial excellence.

The Ota City Industrial Promotion Organization was established in 1995 to support smaller enterprises in Ota City. In addition to organizing trade fairs and meetings for businesses, the organization engages in various other aspects of business support, such as business management assistance, consultation concerning the soliciting and placement of orders, and help in developing human resources.
In 2006, the organization initiated activities aimed at making the "Ota brand" known extensively with a view to helping preserve traditional craftsmanship. At present, having already recognized some 90 companies as meeting its standards, the Ota City Industrial Promotion Organization is promoting "Ota, a town of craftsmanship" to every corner of the world.
