Midfielder Naoya Kikuchi, who was released by J. League club Jubilo Iwata last summer after he was arrested for having sex with a 15-year-old girl, is set to join German second-division club FC Carl Zeiss Jena, it was learned Tuesday. Kikuchi has been on trial at Jena and the club's official Web site quoted a senior Jena official as saying he "made a strong impression." Kikuchi, 23, was arrested in June after he admitted to having sex with the high school student in a car in Hamamatsu, Shizuoka Prefecture, in late May, violating a law prohibiting sex with those under 18 years of age.
