On the other side of the railway tracks to Taga Shrine in Nogata is a small museum on the local coal industry called the Nogata Memorial Hall of Coal.
My father was a coalminer, as was his father, and I grew up near a big coal mine, so I have a particular interest. As a young lad I was a trainspotter so also have a soft spot for old steam engines of which there were a couple on display complete with puffing and whistling soundtrack
Most of the interesting stuff is lying around outside, but there are some displays inside.
I wrote a lengthy article on the place and the history of coal in Japan which you can read here.
