However I do know these captivating photos are indeed of Tokyo’s G-Cans Project— an underground water draining system to help prevent the overflow of major waterways during the wet typhoon season. Just seeing the sheer size and design of this construction through these photos, which almost look illustrated, is amazing. I can only imagine what construction and upkeep of such an immense and interesting system like this must be like. It’s also a free tourist attraction, presumably only during the dry season.Josh Spear

I visited a huge underground water storage system underneath Istanbul a few years ago, dating from the 4th century!! I will have to look for some photos of that. If I can’t find any on the net, I have some old fashioned prints I can scan.
Here you go – I found this photo on the net:
