Take exit #3 at Shin-Nakano station, turn right at the stop of the stairs, head to the nearby intersection and cross to the far side (i.e., cross twice, to the side with Welcia pharmacy).
Walk down the main road (Ome Kaido) for one or two minutes. You will pass a shoe shop, a police box, a temple and finally a carpet shop called Galata Bazaar.
Turn left at the next side street and you will see our office one shop down. Our office has "Fontana" written in blue on the window.
