Shot at KITTE in Marunouchi, Tokyo.
I entered into a shopping mall called 'KITTE' operated by Japan Post. 'KITTE' means 'Stamp' in Japanese. There was an atrium lobby inside. And I could see many shops doing business on the each floor. It was not crowded and I walked around in a leisurely fashion.
The wall was separated by the pillars and the floors. I thought as if they were cells. And I could find wriggling people in the each cell.
