Less than two months after Devon Aoki was cast as Katana on Season 3 of Arrow, the actress was forced to step aside due to scheduling conflicts. Rila Fukushima (The Wolverine) has signed on to take her place.
Rila Fukushima will have a major recurring role as Katana, a Japanese martial arts expert who is seen in flashback sequences during Oliver Queen's (Stephen Amell) time on the island. She will be joined by Oliver's other mentor, Maseo Yamashiro, played by Karl Yune. It isn't known how many episodes of Season 3 that Rila Fukushima has signed on for.
