A question from Yahoo! Answers:

Where did the name Nissan for Japanese cars originate?
Does anybody know the meaning of it?

Is it a Japanese word?

ISNT THIS A JEWISH CALENDAR MONTH OR SOMETHING?

Nissan is an abbreviation of the official name “Nippon Sangyo” (“Japan Industries”), under which the company was founded by Yoshisuke Aikawa in 1928. Until 1933, Nissan did not produce cars, but manufactured mainly vehicle parts. (As a side note, at the time Nissan also owned Hitachi.)

As to the the Jewish calendar, the month’s name is spelled “Nisan”, with one “s”.
