I wrote about the transfer among Kyoto, Osaka and Kobe in the previous post. There are lots of railways by Japan Railway and several private railways, such as Hankyu, Hanshin, Kintetsu and Keihan. This means you have many many choices to choose the ticket or pass. All private railways have own pass. And also JR West has Kansai Area Pass. You may be overwhelmed to choose the right ticket.
In this post, I would like to share the information about the discount ticket and pass that cover Kansai area. But if you stay in Kyoto or Osaka and visit the places in the city, you may find the deals in the links below:
Mt. Koya (Koyasan) has been getting popular destination in these days. Most common way to Mt. Koya is Nankai Railway line. It takes you to Gokurakubashi station where is located at the base of Mt. Koya. You may transfer to the funicular to Mt. Koya.
If you use JR deals, such as JR Pass (nationwide pass), Kansai area pass, Kansai Hiroshima area pass and other JR West passes, you cannot use the pass because Nankai Railway is not JR. If you do not use these JR deals, you may use other deals, such as Kansai Thru Pass, Koyasan World Heritage Pass.
You may use these JR deals partially to get Mt. Koya if you want.
