Providing trust with
our products & services

JustSystems Corporation was founded in 1979. At a time when personal computers were not yet an integral part of daily life in Japan, and it wasn’t even possible to input Japanese text, the ATOK* Japanese language input system ushered in a new culture of “Kana-Kanji conversion using the space bar.” More than 30 years on, and backed by dependable technological prowess in natural language processing technologies and other fields, JustSystems continues to deliver dozens of products and services to customers in a diverse range of industries and fields.
