Celebrating the 70th Anniversary of Itami Works and the 50th Anniversary of Yokohama Works

In 2011, we celebrate the 70th anniversary of Itami Works' founding and the 50th anniversary of Yokohama Works’ founding. On the occasion of reaching these milestones, we renew our commitment to achieving further growth for Sumitomo Electric Industries, Ltd. and adding new pages to the Company’s glorious history.

Itami Works

Itami Works was opened in March 1941 as the Company’s second manufacturing base. Initially, the facility was dedicated to the production of the cemented carbide tool IGETALLOY and aircraft valve spring piano wire. The facility has since supported Sumitomo Electric Group’s development in the vanguard of group business diversification. Today, Itami Works comprises Production Groups for special steel wire, powdered alloys, synthetic diamonds, sintered components, functional components and compound semiconductors, as well as an R&D Group working mainly on new materials-related projects. Itami Works is a unique industrial site that houses, a wide variety of manufacturing activities, in areas ranging from electronics to automotive and industrial materials and components.

■ Tree-planting Ceremony Marking 70th Anniversary

稲荷祭での植樹の様子

On the occasion of the Inari Festival (celebration of Sumitomo's establishment) on April 3, 80 company executives, headed by Mr. Masayoshi Matsumoto, President, gathered on the premises of Itami Works and attended a ceremony in which prayers were offered for safety of company operations and a yew tree (ichii or araragi in Japanese) was planted to mark the facility's 70th anniversary. The yew tree has thin, long, dark-green leaves, has small flowers that bloom in April and bears red fruits in early autumn. The yew tree was chosen for this ceremony in hope that the Company's operations would rank No. 1 (ichii) in their respective segments.

Yokohama Works

Yokohama Works commenced production of telecommunications cables when it opened in 1961 as the company's first manufacturing base in the Kanto Region. Manufacturing and development divisions, featuring the latest equipment, were gradually added and expanded. Today Yokohama Works is a major manufacturing base of information and telecommunications products, including optical fiber cables, optical connectors, optical fiber fusion splicers, optical amplifiers, and optical and electronic devices. An R&D division supporting the production of these products is also located on the premises.

On-site Science Classes for Local Elementary School Children

On-site science class

On November 24, 2010, Yokohama Works personnel made a "special delivery" of a science lesson about optical fiber to the fifth- and sixth-graders of nearby Senshu Elementary School. The students first carried out an experiment using tin-can telephones, to confirm the transmission of voices via the thread. They then learned the principles of optical communications and actual applications of optical fiber. This was followed by an optical communications experiment in which the students learned to remote-control a video camera using an experimental optical fiber kit. The personnel hope that through such an experience, school children will discover the pleasures of science and become more interested in it.

 
Yokohama Works Site Now and Then

Area before establishment of Yokohama Works

Yokohama Works is situated near JR Tokaido Line Ofuna Station. Before Yokohama Works was built, the area was a vast expanse of paddy fields, with Mt. Kikkou standing in the middle like a floating island. In those days, eels, crabs and shrimp were found in abundance in the nearby Kasio and Sekiya Rivers; hares, weasels, ducks and Chinese bamboo partridges inhabited the surrounding fields. In the 1920s, a score of red swamp crawfish, imported from North America for use as feed on Kamakura Frog Farm (then located in Ofuna), escaped and spread throughout Japan. By the mid-1930s, large numbers of red swamp crawfish were seen in rice paddies on the present site of Yokohama Works, which came into being in such a nature-rich environment.
