Iwasaki Language Program Development(ILPD) is
a private institute which was established in 1992 by Mikiko Iwasaki.
Its first aim was to complete the MISJ(Mikiko Iwasaki's Systematic Japanese) as an ideal Japanese learning/teaching system. However, after 90% of the system had been established, its aim was shifted to promote the system for helping both students and prospective Japanese language teachers.
