[5] This Blue Ribbon Award-winning role, quite different from the one in the original work written by author and designer Nobara Takemoto, was loosely based on Tsuchiya's actual story which she later revealed after the movie's release.

[8] Although born and raised in Tokyo, she sometimes uses Kyushu or Okinawa slang and speaks in southern dialects especially when she is drunk and on the radio.[why?]

[9][user-generated source] Tsuchiya sang in her school choir[10] and has been involved in the music industry since age 16.

At 18, she terminated her contract with Japanese Seventeen, and supposedly decided to leave show business altogether.

[11] Tsuchiya has said her influences have changed over the years, from Whitney Houston, Diana Ross, Cyndi Lauper, Bette Midler and Mariah Carey, to Bon Jovi and Guns N' Roses.

On August 24 of that year, she released her first mini-album, Taste My Beat, on Avex Group's sub-label, Mad Pray Records.

A quasi-soundtrack album called Nana Best was then released, which included popular and unreleased songs by both her and Olivia Lufkin from the TV series.

Tsuchiya released a third single in September 2008, "Virgin Cat", which was used to promote the show The L Word in Japan.

In 2008, Tsuchiya's song "Guilty" was featured in the ending credits of the film Resident Evil: Degeneration.

[17] In 2009 Tsuchiya performed a set with a full orchestra at the New Classic Gig in Tokyo, revealing herself as a fan of Chopin and his "Revolutionary Etude" in particular.

She decided to record the song because her son was a fan of the previous series, Kamen Rider OOO.

In 2012, Tsuchiya's song "Carry On" was featured in the ending credits of the film Resident Evil: Damnation.

[3] Tsuchiya's success in acting continued with various movie performances and appearances in dramas such as Katsuhito Ishii's The Taste of Tea which played at Cannes, the 2007 live-action remake of Dororo, and as the voice of Lindsay Lohan's character "Maggie Peyton" in the Japanese dub of Herbie: Fully Loaded.

[7] In February 2007's Sakuran[20] she played the rebellious but beautiful courtesan Kiyoha in a live action adaptation of the manga.

[21] In addition to acting, she has also been known for her impersonation skills, of many martial artists and wrestlers, most notably Wanderlei Silva, Melvin Manhoef and Jun Kasai.

On November 19, 2004, Tsuchiya gave birth to their first child, a son named Sky (澄海, Sukai) who is featured in a photobook with his mother, titled, Happy Days – Anna, Mama ni Naru!.

"[10] In September 2009, Tsuchiya wrote on her blog that she was pregnant and had married her long-time stylist, Yamato Kikuchi.
