Willow Moonwind Johnson was born on 3 April 1977 in Vancouver, British Columbia, Canada. Her acting career began early in life while she was still a child doing stage work before landing her very first voice role at the age of 12 in the 1989 cartoon Camp Candy, opposite John Candy.
Since that time, Willow has become known for her various roles in many popular anime, most notably her roles in various Rumiko Takahashi stories. Among her most famous roles include those of Kasumi Tendou (Ranma 1/2) and Kikyou (Inuyasha), while other notable roles include her portrayals of Lily McGuire (Fatal Fury), Ruby Moon (Card Captor Sakura), Yukari (Escaflowne), and Tomihime (Ayakashi - Samurai Horror Tales).
She has even dubbed three times for Japanese seiyuu Kikuko Inoue in the roles of Kasumi, Lily, and Yukie in Mermaid Scar. It could be noted as well that in playing Kasumi, she portrayed the older sister of Akane Tendou who is voiced in Japanese by Noriko Hidaka, who also provides Kikyou's Japanese voice.
When Willow isn't voice acting she an be seen occasionally on television in often very brief guest roles in Canadian television programmes. Her most notable mainstream guest appearance was as the young school teacher, Ms. Welsely, in the 1994 episode The Cross of St. Antoine of the Highlander television series starring Adrian Paul. Her other notable television credits include her appearances in the Canadian teen drama series Madison (1994), The Chris Isaak Show (2001), Godiva's (2006), and on Canadian Idol in 2007.
During her free time, Willow has made very rare appearances at anime conventions or other related fan events. Her only known guest appearance was at AKON 2001 in her hometown of Vancouver along her Ranma 1/2 and Inuyasha costars Paul Dobson (Happosai, Naraku) and Richard Ian Cox (Male Ranma, Inuyasha). Willow will be set to appear at this year's Otakon in Baltimore Maryland over the weekend in August. This will be Willow's first con appearance since AKON 2001 and her very first con appearance in the United States of America.
