Annandaira was a ski area located in Yamanouchi Town in the northern region of Nagano Prefecture. It was on the lower western slopes of Boderayama, about 3km off Route 292 at a point before the road starts to climb up to the Shiga Kogen area. Annandaira opened in 1980 and closed in 1986 and so only had a short lifespan, but it has a fascinating story:
