Nakagawa first began her career in 2001, but her initial fame began with her hosting of Pokémon Sunday (which she still remains on) and hit her big break in music after she was chosen to sing the opening theme of Tengen Toppa Gurren Lagann "Sorairo Days" in 2007, which was her first single to reach the top of the charts. She is an avid blogger, and for a time had the most popular blog on the Ameblo blogging service, with over 100 million hits in April 2006 and well over 1 billion hits 2 years later.
Her otaku status has no bounds, with particular reverence to Bruce Lee, JoJo's Bizarre Adventure, and Super Sentai, among many others. While she was originally represented by Jackie Chan's talent agency in Japan, she thought he wasn't a nice man because he was sometimes the villain in Bruce Lee movies. Aside from getting to interview Hirohiko Araki and get him to draw what he perceived to be a possible child between herself and Jotaro Kujo, she once did a JoJo pose on stage during one of her concerts and managed to break her tailbone. She had reportedly auditioned to be the Pink Ranger in multiple Super Sentai series due to her love of Yuri / Time Pink in Mirai Sentai Timeranger, and it was her admiration of Yuri's actress Mika Katsumura which actually inspired her to start acting rather than her late father. She even thinks Shigeki Hosokawa of Kamen Rider Hibiki (among other shows) fame is the ideal man.

- Promoted Fanboy: Shokotan finally got to star in a Super Sentai in Tokusou Sentai Dekaranger...as the voice and human form of a tiny pig-like alien who appears in only one episode.
- Spell My Name with an S: Later in life, she discovered that the name she had been using her whole life was not actually her legal name. After her mother's chosen name of "Shōko" (薔子) was rejected by the Japanese government because the first kanji wasn't allowed to be used in names, her aunt wrote the name in the family registry in hiragana instead but wrote the yo too big, so instead of her legal name being "Shōko" (しょうこ) it ended up being "Shiyōko" (しようこ). Professionally, she's written her name as "Shōko" (翔子), but she usually just goes by "Shokotan" (しょこたん).
