Akechidaira Plateau (明智平) is located near the top of the ascending Irohazaka Winding Road. At the plateau, there is a parking lot with a free observation area that offers nice views onto the Irohazaka and the valley below. During autumn, this becomes a popular autumn color spot as fall colors spread across the landscape.
A rest house stands beside the parking lot, serving as a souvenir shop, cafeteria and the lower station of the Akechidaira Ropeway. In three minutes, the ropeway carries visitors to an observation platform further up the mountain for spectacular views over Kegon Waterfall and Lake Chuzenjiko. Outside of winter, it is also possible to reach this upper observation deck in about two hours (one way) via a hiking trail from Lake Chuzenjiko. The trail also connects to Mount Hangetsuyama.
The Akechidaira Plateau is located along the ascending road of the Irohazaka Winding Road and cannot be accessed from the descending road. Two-way traffic between Chuzenjiko Onsen and the Akechidaira Plateau was abolished in 2019.
From JR or Tobu Nikko Station, take a Tobu bus bound for Chuzenjiko Onsen or Yumoto Onsen and get off at the Akechidaira bus stop (35 minutes, 1100 yen one way, 3-4 buses per hour). Buses in the opposite direction do not stop at Akechidaira.
