Azabu Juban / Minato-ku
Take the Namboku or Oedo subway lines to Azabu Juban Stn. Use exit #4 at Azabu Juban.
At the top of the escalators turn 180 degrees to your left (opposite the direction you exited the stn)
you will see a small drugstore with a pedestrian crossing over a very wide road that you will need to cross.
