In the ancient time, Emperors, aristocrats and pilgrims have to ride horses or walk all the way to visit the grand shrines in Kumano. It was a tough long journey that might take a month depending on the starting point. Today, you may take JR and buses and complete the pilgrimage journey in 5 days, visiting the Ise Grand Shrine, Kumano Sanzan which include Kumano Hayatama Grand Shrine, Kumano Nachi Grand Shrine and Kumano Hongu Grand Shrine; as well as stopping over Kawayu Onsen and visiting Nitama the Stationmaster cat at Kishi Station.
The 5 days Ise-Kumano-Wakayama Area JR pass allows you to travel between Nagoya and Kansai, covering Ise, Kumano and Wakayama.
Please note that you will have to buy the JR Pass before you arrive Japan and redeem it at Nagoya Station (not at Chubu Airport) or Kansai Airport. Activate (redeem) the pass on the day you start using it for the next 5 days.
