Same thing I remember from way back in '92. We weren't in one of those 4wd trucks, we were in a Lexus car. I remember having to back up and move forward around a particularly sharp switchback and like JR, I was sure we were all about to fall off the mountain and die! We picked up an old woman walking along the road with a basket of firewood on her back and carried her to the other side of the mountain.
The fella that owned (leased?) the place at the time was a hotelier from Tokyo and a "hobbiest breeder". I purchased an old doitsu sanke female there, I was told she was from one of the hotels in Tokyo and was over 20 years old at the time. I still have her, in fact she has had a large spawn this season already.
The photo of the unusual shaped cabin, the concrete pools, and the background hit me like a hammer. I've an old slide photo (no digicams then) of the same place with me, Ukari Suda (Atsushi Suda's daughter) and her friend from Niigata City, Wendy (California girl teaching English in Niigata). Tough trip for me, having to sit between a beautiful Japanese girl and a beautiful California girl all day long as we drove from farm to farm buying koi.
I see from the photo on Mark's blog that electricity made it up the mountain. When I was there in '92 there was a generator to run the holding pools and give power to the shed.
