Film Identification

[Ken Shima]

Hello all,

I saw a film last year in Tokyo, from sometime in the 60s I believe  
and I can't for the life of me remember the title. It was a kind of  
Wrong Man detective story filmed in B&W.
	The premise is that a young mechanic in Tokyo finishes his last day  
of work, uses hard-earned money to buy a new car which he drives to  
meet his fiance who works as a nurse in a countryside hospital in  
Tohoku. She is quitting that day in anticipation of his arrival.  
Speeding north along dirt interstates and mountains he passes through  
a small town where a young man about his age flags him down for a  
ride. His passenger only rides to the other side of town and is let  
off at a bridge. Around the next corner, now alone the protagonist is  
flagged down at the police box and arrested for a murder committed  
minutes ago right around where he picked up the passenger thus  
beginning the wrong man angle.
	There are some striking scenes in this film where the detectives,  
prosecutors, defendant, and the victims all recreate the night of the  
crime at the scene of the crime, right down to having the victim's  
wife lay in bed next to a cop playing the role of the murdered husband  
in order to work out the details of the event. Through this  
traumatizing process the daughter character cracks and reveals that  
real events of that night. She had hide her testimony to cover up the  
fact that she was having an affair and had been watching with her  
lover from the roof of the house.
	After many months in jail and a number of fishy stories, extensive  
investigation by a detective or maybe friend of the protagonist  
reveals the murder weapon buried along the riverside and the real  
murderer caught in some yakuza debt in Tokyo. This sets the  
protagonist free to curse small town cops and narrow-sighted villagers  
as he speeds away with his wife and their new car honking in a cloud  
of dust.

Although I remember the plot pretty well, I can't for the life of me  
come up with the title of this film. Also, I keep getting it mixed up  
with Yamamoto Satsuo's "証人の椅子". Any ideas would be a help to  
my failing memory and greatly appreciated.
