Okita has also acted in numerous mainstream Japanese language films, such as Naked Ambition 2 (2014), Assassination Classroom (2015), Scoop!

Okita was an art student in England during her college years but she also started to take modelling jobs and became a gravure idol before her AV debut.

For the next two years Okita remained as an exclusive performer at S1[3] and was featured in twenty adult films with the studio, thus becoming a major player in the AV landscape as a newcomer.

With her exotic looks and voluptuous figure Okita's popularity increased rapidly from mid-2011 onward in Japan as well as other Southeast Asian markets.

In 2013, Okita's popularity exploded in the United States and Canada as well as Europe; she became the third watched Asian porn star after Hitomi Tanaka and Yui Hatano.

One was J & L – Two Pairs Of Huge Tits Take Real Creampies (released by Moodyz in June 2015)[9] in which she co-starred with fellow AV actress and close friend Hitomi Tanaka.

She was also part of Moodyz 15th anniversary work, Crimson Dream, an extravagant live action adaptation of a hentai manga with a runtime of six hours and a cast of other highly popular Japanese adult film actresses like Ai Uehara, Kaho Kasumi, Kurea Hasumi, Yui Hatano, Hibiki Otsuki, and Shoko Akiyama.

In 2011, while still in the adult industry, Okita appeared in one episode of the popular Japanese tokusatsu television series Garo: Makai Senki.
