ちょうど道を渡ったところに right across the street
The building and the street seem like one in a European country. Actually the place is right across the street from the Imperial palace, around Hibiya area. The street one block away from here was crowded. This sidewalk, however, was quiet. It would be a nice walking route.
★This old building is Nihon Seimei Building. I wonder how old the building is?
