TV Tokyo remakes one of the most famous TV dramas of the '90s, "Keiji" ("Detective"; Wed., 9 p.m.), which originally ran on NHK and starred Ken Takakura. This new version has Katsunori Takahashi in the titular role of Minoru Akiniwa, who works for the No. 1 Investigative Division of the Tokyo Metropolitan Police.

Akiniwa's entire life is defined by one tragedy. His wife (Maki Miyamoto) was shot in front of his eyes by a man named Tanabe, who Akiniwa had put in jail. He vowed revenge and eventually got it. Now he may have to relive that pain when his former subordinate and friend Murasawa is stabbed to death at his new assignment in the waterfront area. Akiniwa immediately goes to the crime scene and though it isn't his case he secretly vows revenge against the perpetrator.

In preparation for the Japanese broadcast of the third season of "Sherlock," NHK has commissioned superstar scriptwriter Koki Mitani to create a three-night series based on the iconic British sleuth called "Sherlock Holmes: Kimyo-na Gakuen" ("Sherlock Holmes: Bizarre School"; NHK-g, Tues.-Thurs., 7:30 p.m.)
