The Shinkansen has regular service from Kyoto station every 15 minutes to and from Tokyo
It connects all the way to Kyushu in the south and Hokkaido in the north but it is typically cheaper to fly to these destinations via one of the airports in Kansai (Kansai international airport, Itami Osaka international airport, Kobe regional airport)
