Pink Tentacle shares this clip exploring an underground warehouse (apparently one of many built by the Tokyo Metropolitan Government) that contains supplies for citizenry in case of emergency.

Located 20 meters (65 ft) underground, the 1,480 square meter (16,000 sq ft) space contains emergency supplies to be distributed to the public in the event of a major earthquake. Items include 5,000 blankets, 8,000 rugs, 4,000 candles, 300 cooking pots, 200 t-shirts, and emergency medical supplies. A conveyor belt system is installed to help transport the supplies up to street level.

I knew they took Godzilla more seriously than they let on!
