The 'River line' features numerous bridges, small tunnels and galleries, as well as a variety of rolling stock including Kiha 185-series trainsets that were some time ago offered in N scale by MicroAce. It is also notable for its picturesque surroundings, small towns along the banks of the river, and the mountains that still dominate the whole landscape.
Both parts of the line feature stations and towns that are so small that they almost look like a model train layout.
Sakamoto station is the third station of the Hisatsu Line. The station has two tracks and a wooden station building. Stop signs for freight trains led by the mighty D51-s are still preserved. The station was opened in 1908, and became unmanned after the electonic blocking was introduced in 1986. According to data collected in 2006, the station is used by 91 passengers daily.
This station was brought to my attention by the following photo posted by goagoa on Panoramio:

Impressed by the site's completeness and character, I have taken some time to count all the houses in the area surrounding the station. It turns out there are no more than 70 buildings at all. Fore one who would desire to model a complete station of a DMU-powered railway in Southern Japan, this is a very attractive prototype. Reducing the number of houses and the required length of track by what is called the selective compression, one would be able to reproduce the same picture by a modest amount of buildings and detail.
As far as operations are concerned, there used to be some freight traffic on this section of Hisatsu Line. Besides, according to Wikipedia, about 1 km away from the station there is an industrial branch, so there may still be an occasional movement of goods - no further information for these branches is available.
All station signs on the Hisatsu Line have an image painted on the station sign. The sign for the Sakamoto station features an observatory. One would never tell from the rural look of the neighbourhood that some serious scientific research is going on, however the place seems more than convenient for this type of activity.
