Could you be thinking of Kishimojin?

If you are, you can try these links--

She's also known or associated as Hariti as well, hence some links with that name.
Hariti is also compared to--
Kangimo (Japanese: 歓喜母 "Bringer of happiness)
Karitei (Japanese: 訶利帝, Shingon name)
Kariteimo (Japanese: 訶梨帝母, another Shingon name)
Kishimojin/Kishibojin (Japanese: 鬼子母神)
Koyasu Kishibojin (Japanese: 子安鬼子母神 "Giver of Children and Easy Delivery")

I can't find much, if anything on the specific spelling you gave. Maybe there's a confusion with the transliterating? Where did you see that spelling?

I know Benzaiten (http://www.onmarkproductions.com/html/benzaiten.shtml) is associated with arts, music, beauty, language, dance and things like that. I also saw Marishi-ten being mentioned with geisha and samurai.

Ah, wait, there's a Kichijouten. Could that be her?

She's associated with Lakshmi. In Japan she is the goddess of fertility, fortune, luck, beauty, and merit.
