Train system in Kyoto may be complicated for you. There are three types of railway, JR, Kyoto City Subway and Private company’s railways. Actually it’s a key to travel in Kyoto smoothly and avoid wasting your valuable time. Of course city of Kyoto has city wide bus service. But during peak season, bus service runs behind the schedule sometimes due to traffic congestion.
And also, there are many types of deals, such as ICOCA, Kansai Thru Pass, JR Pass, Kansai Area Pass, Kyoto city pass. Each pass has different conditions. You have to understand which train system is covered by your pass.
If you visit Osaka and make some day trips to outside Osaka, such as Kyoto, Nara, Kobe, Kansai Thru Pass is a good deal. But as I explained about this pass on the post, How to use Kansai Thru Pass. Compare pass and single fare, you have to make many train and/or bus trips. And I compared a regular fare and the price of pass in the link above. But it may be complicated for you. You may be overwhelmed.
I will show you some sample itineraries by using Kansai Thru Pass in this post. I hope this post let you understand this pass easier.
Miyakoji Rapid Service is the fastest local train that is operated between Kyoto (=京都) and Nara (=奈良). Most of local tourists take Kintetsu (近鉄) line to Nara. Because they have many more trains and very frequent. If you travel in Japan without Japan Rail Pass, you may use Kintetsu line. But most of travellers from foreign countries use Japan Rail Pass. So this Rapid Service is your best choice, because you don’t need to pay any extra. This line used to be very local and inconvenient. But JR West upgrade the trains and timetable. Now JR West operate many Rapid trains. It is very convenient and frequent departure these days.
