Devon Aoki Joins 'Arrow Season 3 Cast as Tatsu Yamashiro

The cast of Season 3 of the CW's Arrow has gained a new member, as actress Devon Aoki has joined the show in a "major recurring guest role," according to Deadline.

Aoki will play Tatsu Yamashiro, a character who first appeared in the Green Arrow origin series published by DC Comics. Deadline describes her as "a Japanese martial arts expert who wields a deadly sword, a blade from which her codename Katana is derived. In Arrow, Tatsu will be one of Oliver's mentors in the flashbacks and a critical influence on his journey to eventually become The Arrow of present day."

The actress previously appears in 2 Fast 2 Furious, Sin City, D.E.B.S. and War.

TVLine previously reported on four new characters for Season 3, and it seems as though "Akiko" is actually Tatsu. Here are the full descriptions the site posted in June:

Daniel: Though Daniel could be a fake name to throw off spoilerholics, this 20something gent - a major recurring character for Season 3 - is a handsome, enigmatic and highly intelligent entrepreneur developing groundbreaking technology. (Picture a business magnate in Ryan Gosling's body.) Though exuding charm and confidence in public, he privately harbors a tragic past that will drive him to become a tech-powered superhero. Watch for this formidable fella to be a love interest for Felicity and a rival of Oliver's - both personally and professionally.

Seth: A well-educated criminal with grand ambitions and a knack for chemistry, this potentially recurring character gains power over his enemies by exposing them to a drug that drains their willpower. Oh, and he is very much a physical match for The Arrow.

Toshi: Majorly recurring in (at least) the Hong Kong flashbacks, Toshi (late 20s/early 30s) will serve as Oliver's teacher and handler, and eventually become a friend. A well-trained operative, skilled in weaponry, combat and intelligence gathering, he is also a devoted father and husband.

Akiko: Toshi's wife is another of Oliver's Hong Kong caretakers, and is herself highly skilled in martial arts.
