Waiting in hotel rooms, waiting for rain delays, waiting for matches to start. There is excessive downtime.”At the 2025 Japan Open Tennis Championships, Taylor Fritz’s love for Tokyo was on full display as he delivered some incredible performances at the ATP 500. The American made it to the finals of the event before going down against Carlos Alcaraz.
