But to implement that idea, there needs to be a change in the national law, and how effective the plan would ease travel congestion for residents is still unclear. [...] While the increase in tourists means more money for the local economy, it also means crowded buses and subway stations, traffic jams, long lines at Kyoto's famous temples and shrines, and street garbage, leading to many residents' complaints and calls for action. Matsui promised to tackle the over-tourism problem in several ways, including calling on the central government for legal revisions that would allow Kyoto buses and the subway system to charge visitors higher fares while charging residents lower fares than they are now. Currently, the fares are the same for everyone. The system's purpose would be to prioritise the transportation needs of residents and discourage overcrowding of buses and subways by tourists.
