Consider this a late trip report. About 4 years late, to be exact.
In April of 2008, I made the journey to Sayama ski area in Saitama. Sayama is an indoor ski area, consisting basically of a long roof placed on a hill, with two single-chair lifts on either side of the single gelaende, which measures 320 m long. Obviously, the snow is entirely artificial. Surprisingly, the walls are not enclosed -- there are some plastic curtains between the slope and the lifts, with the curtains being open most of the day. The lifts are under the roof, but open to the outside. Sayama is located next
