It is said that the name of Irohazaka was given because the early Irohazaka had 48 hairpin curves.

The current “Irohazaka”, which was improved from the early Irohazaka, is divided into the first Irohazaka for downhill on the north side and the second Irohazaka for uphill on the south side so as to sandwich the Kegon Valley where Kegon Falls is located. The 48 curves that exist on these two slopes are likened to the 48 sounds of Irohazaka, and those signs are built on each curve.

The two slopes meet at the foot of the mountain and on the shores of Lake Chuzenji.

There are 20 curves from “I” to “Ne” on the second Irohazaka, which is a one-way uphill road that climbs to Lake Chuzenji. And there are 28 curves from “na” to “n” on the first Irohazaka, which is also a one-way downhill road to the foot of the mountain.

In the middle of the second Irohazaka, there are two parking lots, “Kurokamidaira” and “Akechidaira”, which also serve as rest areas.

There is a ropeway station in Akechidaira, and you can see Kegon Falls and Lake Chuzenji from the Akechidaira Observatory at the end of the ropeway.

I uploaded some videos of Irohazaka which is taken with my TDM900.

I hope you enjoy!
