Kenji was a Japanese black market dealer set up in Shanzhai, Vietnam.
Tom Chandler captured Kenji in his search for Takehaya and his kidnapped crew after seeing him wearing Mike Slattery's dress shirt. When confronted at gunpoint he reveals he bought the shirt from some people in Vietnam and flees with them after the Chinese MSS arrive. He was killed in a shootout later by the MSS as a form of suicide after telling Chandler Takehaya actually gave him the uniforms to burn. (“Shanzhai”)
