Classic ’90s police drama gets remake; Koki Mitani pens “Sherlock Holmes: Bizarre School” mini-series; CM of the Week: Boat Race Promotion Agency

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.)

In Mitani’s version, which has been adapted for puppets, John H. Watson is a exchange student from Australia at the Beton boarding school in London. His roommate is Sherlock Holmes, a “problem child” whom the other students find unfathomable, but he instantly takes a liking to Watson.

CM of the Week: Boat Roace Promotion Association

Boat racing is one of the four “public sports” — a euphemism meaning you can gamble on them. Lately, ads for motor boat racing has used women in color-coded costumes.

The latest features a chorus line of six women in shiny cat suits dancing suggestively to a hard rock song. The focus of attention is the woman in red, who is not only plus-sized but the wildest dancer in the group. At the end of the spot the camera zooms up on her masked face and the words “Guess who?” appear on the screen.

No prize for a correct answer. Big girl? Good dancer? It has to be Naomi Watanabe, who first made her name as a TV personality lip-syncing and dancing furiously to Beyonce songs. Apparently, the series will continue with more mystery dancers.
