MESCIUS inc. was founded in Sendai, Japan in the early 1950's by a group of American educators in Japan. With a focus on high-quality English education, this small group established

world-class elementary schools in northern Japan. After nurturing the schools to success, there was a realization that the company had software needs not met by what was on the market. So, MESCIUS expanded into technology and software to create what was needed. MESCIUS’ family of products provides developers, designers, and architects with the ultimate collection of easy-to-use tools for building sleek, high-performing, feature-complete applications. For over 40 years, MESCIUS has provided enterprises around the world with state-of-the-art developer components, software services, and solutions.
