Pictures are displayed alongside the work of graffiti and rock artists Inkie and Vince Ray.
One winner will receive an exclusive We Are Tekken version of Tekken Tag Tournament 2, a Kotobukiya Yoshimitsu statue, a T-shirt, bowling bag and Vince Ray's Anna Williams poster signed by Harada-san.
The event was also attended by Jim Vision from street art and graffiti group End of the Line. Vision produced a huge backdrop of Tekken character Devil Jin during the course of the evening.
