Bframe5 brought something interesting to me attention about the Amazon jdorama Chase. From the Japanese wikipedia entry, it seems that although the Chase says that it is a work of fiction, the story and the murders in the jdorama are essentially the same as the real life Ashikage murder case.
The article also says that the makers of Chase did not interview the victims' families nor did they seek their permission and ignored their feelings. Because of this, Amazon stopped the distribution of episode 7 for a short while.
I have no idea why the creators did not just say it was based on real life events because the story of the reporter and the ending is the same. Maybe there are monetary reasons for it.
The facts that it is based on real life just makes the story all the more interesting. I will get to season 2 once I find time. I find Chase a very watchable show and hope everyone sees it.
