(1914). 〕 ==Work== Ajima is credited with introducing calculus into Japanese mathematics. This significance of this innovation is not diminished by a likelihood that he had access to European writings on the subject.〔Restivo, Sal P. (1992). 〕 Ajima also posed the question of inscribing three mutually tangent circles in a triangle;〔.〕 these circles are now known as Malfatti circles after the later work of Gian Francesco Malfatti, but two triangle centers derived from them, the Ajima–Malfatti points, are named after Ajima.〔.〕〔C. Kimberling, (Encyclopedia of Triangle Centers ), X(179) and X(180).〕 Ajima was an astronomer at the Shogun's Observatory (''Bakufu Temmongaki'').〔Jochi, Shigeru.
