I've just watched a film "Our little sister" shot in Japan in 2014. As well as several urban electric railway sequences set s.w. of Tokyo there is a scene filmed at a rural station on a single track line, using a single maroon painted diesel railcar. All film references on google yield only city locations, but clearly this is not. I'm really interested to know where this line is. Has anyone seen the film (currently on BBC iplayer) and does anyone know where this rural line is?
