An antique Japanese image of a caravan of sorts

Hi. I have got a number of images- old paintings and prints of Japanese origin, these were collected during the late 1940s and 1950s (immediately after World War 2) by my late grandfather who was posted in Japan (Tokyo) on official work. Most of these prints seem to be later copies of famous works by some of Japan's older and well known artists from the 19th c. However, I have this one painting or image that nobody and no site seems to identify. 

This depicts a caravan of sorts, or maybe the entourage of some famous or powerful person , passing through a typically Japanese landscape. I can also see a mountain in the background, is that Mt Fuji? There are two persons on horseback and the rest walking. What does this scene depict? Approximately how old is this (it is a framed image) ? And who is the artist? 

I would be grateful for any help/ideas. Thanks.
