Almost all JASP presentations use English as the primary presentation language, including the visual presentation slides.  However, some JASP Speakers can also provide occasional verbal explanation in Japanese when needed.  A few can also give verbal presentations mostly in Japanese.  We try to give special attention to pair a suitable JASP Speaker with each Host Professor’s class, and usually find that neither English level capability nor general academic level is a big issue for university students.  We also find that use of professional translators does not necessarily work especially well for JASP storytellings.
