Shizuoka Business Office (Izu-Nagaoka Factory)

Izunagaoka Factory was newly established in 2019 (the first year of Reiwa era), as a mother plant of Ihara Science furnished with state-of-the-art production equipment on a vast site. By concentrating our research and development departments across the company for products and services, production technology, and plastic forming technology, etc., the Factory will respond to customers’ diverse demands as a development and production base.

Shizuoka Business Office (Nakaizu Factory)

Nakaizu Factory has served as a base of product development and production technology development. The current factory located in Shimoshiraiwa, Izu City, specializes in producing valves (with diameters from large to small) and units for clean fluids mainly used in semiconductor and liquid crystal fields.

Yamagata Business Office (Yamagata-Ihara Co., Ltd.)

In 1982, Yamagata Business Office was established in Higashine City, Yamagata prefecture, as “Yamagata-Ihara High Pressure Corporation”, a wholly-owned subsidiary of Ihara Science Corporation. “Yamagata-Ihara Co., Ltd.” mainly produces stainless steel fittings for stainless and plastic tubings, and various valves. Although our company is well-known for bite-type tube fittings, we also develop new stainless fittings one after another, which are not available from existing manufacturers. We have created a processing line that aims short-term delivery of not only mass-produced products but also small lots and many kinds of customized products, which other companies are not good at producing. Trough breaking the common sense that selecting fittings from catalogs as general-purpose products is the cheapest and fastest way, we, as a stainless fittings maker, currently gain a lot of trust from major users.
