Nishiyama in Old Bitchu Area

I set out from Takahashi to Bitchu's Nishiyama having seen one picture of a view from one of the lodges they have there on a tourist map. The road is winding and fairly long but it's a beautiful drive on a nice day. You drive by a seclusive reservoir, up the mountain to a camp site with fantastic views from the top. There are tennis courts and a park that to be honest have seen better days, but you will probably have them all to yourself. Was this once a vibrant holiday destination? I'm not sure, but it's a nice drive.
