We took a bus from in front of Yunomine Onsen to Shingu along the Kumano River. There were several foreign tourists on the bus. They got off the bus at the roadside station where there is a boat stop. From here, they took a 16-km (1.5 hour) river cruise down the Kumano Kodo to the back of Kumano Hayatama Shrine. On the left side of the road is Kounodori-koshi, said to be the most difficult part of the Kumano Kodo. We arrived at Shingu in about an hour. From here, we took a rent-a-car to the parking lot of Daimonzaka, which leads to Kumano Hayatama Shrine and Kumano Nachi Taisha Shrine. On the way, we had a tuna bowl lunch at a fishing port in Katsuura, Kii. The tuna boxes piled up at the fishing port are unfamiliarly long and thin. They are long and narrow, which is unfamiliar to me.
Daimonzaka, which leads to Kumano Nachi-taisha shrine, is a sightseeing spot where you can enjoy the Kumano Kodo easily, and is crowded with souvenir shops and restaurants in front of the gate. After climbing the last long stone staircase on Mt. Nachi, a large vermilion-lacquered torii gate appeared, and when we climbed further, we found a gorgeous shrine surrounded by the precincts of Nachi-Kumano-taisha, with Nachi-Kumano-taisha sitting in front. After visiting the shrine, we went next door to Seigishikakkoji Temple, the first stop on the pilgrimage to the 33 temples of the Saigoku region. From the temple grounds, we could see the five-story pagoda and Nachi Falls, which has the highest drop in Japan, splashing down from the water.
