Mizar-JAPAN is an organization dedicated to the Mizar system and the development and use of formalized mathematics. Its founding perspective is that computers both demand advanced, precise mathematics and help create new mathematical methods. The emergence of proof checkers and mathematical languages made this work possible, including the Mizar system.

The organization supports a range of activities for researchers and learners. Its TSGA research meetings provide a forum for discussing Mizar articles, applications that make use of proof-checking systems, and related supporting tools. Its publication activities include Mechanized Mathematics and Its Applications (MMA), Works in Progress (MMA-WiP), and Formalized Mathematics, an open-access journal described as a pioneering publication in formalized and mechanically checked mathematics. The journal’s 2022 impact factor was 0.3.

Mizar-JAPAN also offers hands-on tutorials, manuals, and a search engine for the Mizar Mathematical Library (MML). Together, these resources and activities help users explore, apply, and share computer-checked mathematical work.
