Shot at Tokyo International Forum in Yurakucho, Tokyo. The big architecture had a big glass-paneled wall. Among the iron frames, the corridors were running along the wall. I thought it was not made for the convenience because the corridors didn't connect any rooms. So few people walked the corridor.
When I watched the corridor, a businessman emerged into view. He was walking slowly and passing by me slowly. After he walked away, the corridor became deserted again.
