The labels are in Japanese if you want to try with your phone. The intro through Google Translate:
"The survey conducted by the "Kowloon City Expedition" first produced an east-west cross-sectional view. This panorama depicts life when Kowloon City was at its most lively on top of that cross-sectional view. Based on the remnants of life that remained in the area, we have added documentary materials and the results of interviews. If you look at Kowloon City as a whole, where each room was colored by its own lifestyle, you will see that it was a dense city where "anything goes", embracing both the sacred and the profane."
