To determine the travel time to Gyukatsu Motomura in Tokyo via subway, you'll need to know your starting station. However, if you're traveling from a central station like Shinjuku or Shibuya, it typically takes around 15 to 30 minutes, depending on connections and waiting times.
For the most accurate information, I recommend using a navigation app like Google Maps or a dedicated transit app for Tokyo, which will provide real-time directions and travel times based on your specific starting location.
