 "Tani," or "valley," is also a Japanese slang word for the cleavage between the breasts.Consequently, Ms. Tani may have had a variety of puns in mind when she later opened a restaurant calling it the "Ohtani" (Big Breasts or Big Tani).Tani's early films were principally with the small companies that were making "pink films" independent of the large studio system in the 1960s.
