I recognize Kunrei-shiki as the style used in Eleanor Harz Jorden's seminal Japanese textbook, Japanese: The Spoken Language. I always thought Hepburn style was more appropriate for the goals of that book: to convey spoken Japanese in a way understandable to English speakers.

(My Japanese professor was a native speaker, and so used her own voice, not audio materials accompanying the textbook.)
