Kyoto station is so vast. You may be surprised if passing through there without this Kyoto station guide as the background knowledge that is not only a station, but a huge complex facility.

For you who have a time, “How about going exploring, your trip has already begun from this station”.

The red and green illuminated place at the head of picture is the grand staircase.
