The Psychometrer Eiji Series (starring Masahiro Matsuoka, Yoshihiko Inohara, Yuki Kohara, etc) is a MUST watch if you love the detective/mystery genre.
As the title suggests extrasensory powers are involved. The first series starts off with Eiji, the lead character using his powers to visualise scenes or items related to crimes to help solve police cases together with his two buddies - although his ability to harness his powers are rather limited. The second series continues in the same vein as the first but Eiji has greater control over his psychometrery ability.
Cool cast and great chemistry, consistently interesting cases that sometimes take unpredictable, disturbing turns.
