|This article is about a/an actress in Samurai Sentai Shinkenger.|
Takanashi is known mostly for her work with the gravure idol group Pink Jam Princess, and in the 2007 film adaptation of the Japanese novel Goth. She has also appeared in the Japanese TV dramas Detective School Q and Rookies and in the film Kamen Rider W Returns. She later portrayed Emiko Watarase in Neo Ultra Q.
Takanashi ended up "portraying" Mia in the Power Rangers Super Samurai special Halloween episode Trickster Treat, as footage for the episode was directly lifted from its counterpart episode/V-Cinema installment from Samurai Sentai Shinkenger, The Return of Samurai Sentai Shinkenger: Special Act. The portrayal was limited to extreme long shots and her face was barely recognized.
