Today we will have a very early start taking the bus from Yunomine Onsen. The bus will take us to Shingu City. From Shingu we take the local train to Kii Katsura Station where we will catch a local bus in direction of Nachisan, our starting point for today’s hike. After about 30 min on the bus, we will get off Nachi Taki, Japan’s highest waterfall, which we will visit first. Then we will walk up to Nachi Shrine, the second of the Three Kumano Grand Shrines. Near the shrine is a Seigandoji, a Buddhist Temple of the esoteric Tendai Sect. This temple is the starting point for a 33 Temple Pilgrimage dedicated to Kannon, the Goddess of Mercy. It is also a center for Shugendo, an ancient tradition of mountain worship. Many yamabushi (mountain ascetics) still come here to worship and practice. We will have an early and quick lunch (around 11am) in the Nachi area (udon, soba noodles) before starting our hike. We will walk the Ogumotorigoe trail of the Kumano Kodo from Nachi Taisha to the settlement of Koguchi (14.5km; 6hours). After arriving in Koguchi, we will catch a local bus, and change buses a couple of times, to reach Kawayu Onsen. We will have dinner at the minshuku in Kawayu Onsen. In winter, there is time to experience the famous 1,000 people onsen in the Kawayu River. During warmer seasons we can dig our own pool in the riverbed. We need a swim suit to join the locals sitting in the river where the hot onsen water bubbles to the surface. Overnight: Tateishi minshuku or similar.
