Akagisan Dai 1
('Akagisan Number 1') is a small ski hill - the self-proclaimed 'smallest ski area in Japan' - located high up on Mt Akagi in the eastern region of Gunma Prefecture and to the south of the ski areas in Minakami and Katashina.
There are currently no operating ski lifts at Akagisan Dai 1, just a 60m long 'snow escalator', so it is more like an ungroomed playing-in-the-snow type area than a proper ski hill. Akagisan Dai 1 is normally only opens on weekends and holidays.
There used to be two more small ski areas nearby, Akagisan Dai 2 (Number 2) and Akagisan Dai 3 (Number 3), but they are no longer operating. Akagisan Dai 1 itself actually used to be a much larger ski area, complete with a Ropeway and two ski lifts. The full story about Akagisan Dai 1 (and the other two areas) can be found on SnowJapanHistory.com
