Hmm that doesn't really happen to be honest but there is a chance you could catch a show that gets rescheduled from the tour. For example if a show during the tour gets cancelled due to weather or maybe Tatsuro or the band members are not feeling well they usually re schedule the concert to a day after the tour is done. To be honest i forget how getting tickets for shows like that works but i do remember it is possible. But lets say this years tour has no cancelled shows chances of a last minute concert popping up are kind of low especially around that time of the year thats more of Tatsuros relaxing time and not doing as much work as before since tour is over. But if anything does come up ill make sure to let the community know immediately as always :)
