"The Wolverine" actress Rila Fukushima has joined the cast of The CW's "Arrow". Fukushima, who played Yukio in the "X-Men" spin-off, is set to replace the previously cast Devon Aoki in the role of Tatsu Yamashiro on the upcoming third season of the show. The character serves as one of Oliver’s mentors in flashbacks, and is a critical influence on his journey to eventually become The Arrow.
