Irohazaka is a pair of winding roads that connects the lower and higher elevations of Nikko in Tochigi prefecture. The road for downward traffic was built in 1954 and has 28 hairpin turns. On your way down, you will witness a beautiful view of two waterfalls. The road for upward traffic was built in 1965 and has 20 hairpin turns. The upward road leads to Akechidara Plateau, where you can get a beautiful view of the winding Irohazaka roads from the observation deck. Visitors can go up to the observation deck via a ropeway from the parking lot.
The name "Irohazaka" comes from two words: "iroha" and "zaka." "Iroha" are the first three syllables of the old Japanese alphabet, originating during the Heian period, and "zaka" means slope.
