What JustSystems does

JustSystems Corporation is a Tokyo Stock Exchange Prime Market-listed Japanese software company (TYO: 4686), founded in 1979 in Tokushima, that develops office productivity, information management, enterprise software, and consumer products. Its flagship technology is ATOK, the Japanese input method system first released in 1982 and now delivered across Windows, Mac, Android, and iOS via the ATOK Passport subscription service, which combines a proprietary NLP conversion engine, cloud predictive conversion across approximately 2.35 million dictionary entries, cloud proofreading, and the ATOK MiRA generative AI document assistant. The company also markets 一太郎 (Ichitaro), a long-running Japanese word processor, and JUST PDF for consumer productivity, supported by the Just MyShop e-commerce platform and retail distribution.

The enterprise portfolio is anchored by JUST.DB, a no-code cloud database with generative AI-powered design-free development and AI-OCR; Actionista!, an all-in-one BI and analytics platform with a 90%+ annual renewal rate; and JUST.SFA sales force automation. The education franchise centers on SMILE ZEMI, a tablet-based distance learning system serving children from preschool through high school in Japan and, since 2023, the United States (now reaching all 50 states and over 1 million children), with the SMILE ZEMI ENGLISH AI conversation coaching feature added in February 2026. JustSystems serves private enterprises, government institutions, schools, hospitals, and individual consumers, with revenue reaching a record 445 billion JPY in FY2024 generated across roughly 15,000 enterprise B2B customers and 7 million registered consumer users, through a hybrid of one-time perpetual licenses, recurring subscriptions, and professional services. Operations span Japan, the U.S. (JUSTSYSTEMS AMERICA, INC., established 2022 in Torrance, California), and Canada (JUSTSYSTEMS CANADA, INC., acquired 2006 with the XMetaL XML authoring business), with a strategic capital and business tie-up with Keyence Corporation since April 2009.
