Most of the cultivated areas along the route are gardens like this rather than the tea plantations in the previous photo - much of the land along the riverside and bikepath is used for what would appear to be community vegetable gardens. And they seem to be tended exclusively by elderly Japanese women and men dressed in farming garb - surprisingly, no children or young people at all.

The route itself is relatively well-marked, with signs like this here and there to let you know you're on the right path. However, in several places they could use a sign or two - see Nuts & Bolts for details.
