Gion Corner Cultural Show tickets

Are tickets for the Gion Corner show (6;00, 7:00) available for purchase in the tourist center inside Kyoto Station?

For individuals (meaning not as part of groups or 20 or more people), you don't need to book, they say (in the details given in Japanese). I suppose you can just show up for the performance.

I dont think they sell them in the infocentre at the station. You will need to buy them at Gion Corner before the performance. They openthe ticket office of the theatre half an hour before the beginning of the show. When we went there, there were already quite a few people queing for the tickets at that time, so I recommend getting there even earlier than 30 mins before the show.
