I am very happy with this casting. She was awesome in The Wolverine and stole every scene she was in!

The Wolverine star Rila Fukushima is set to replace Devon Aoki as Tatsu Yamashiro (aka Katana) on the upcoming third season of “Arrow.” Deadline reports that Aoki departed the series due to scheduling conflicts.
A skilled martial artist, Katana gets her name form the deadly sword she wields which contains the souls of everyone she has killed, including her late husband. It’s unclear if this supernatural angle will manifest itself in the character in the series, but we do know that she will be important to Oliver’s flashback sequences in the upcoming season. In the comics, the character is closely associated not only with the Birds of Prey but also Batman’s The Outsiders.
“Arrow” airs Wednesdays at 8 P.M. ET/PT on The CW with the new season set to premiere on October 8th.
