Jay Chou, who played the lead role Takumi Fujiwara in the movie, later invited her to appear in his music video Common Jasmin Orange.

Just before her scheduled return to Japan in February 2007, director Wei Te-sheng invited her to take the leading actress role Tomoko in his upcoming Cape No.

Taiwan in 2008 named her the third most visible person on the news, after former president Chen Shui-bien and late businessman Wang Yung-ching.

In the film, Tanaka attempts to reconcile with her sense of identity after starring in Cape No.7 by travelling to sightsee in Kaohsiung, during which she finds unexpected love.

She appeared in the 2013 Chinese film The Chef, the Actor, the Scoundrel, as a Japanese officer and fellow alumni of the main characters from Yenching University.
