Older videos of Japan’s impressive underground bicycle parking have been seen on the Web before, but this new video featuring the topic is trending again now. As biking is so popular in Japan’s congested urban areas, engineers have created a very unique way to park all those bicycles: underground.

The entire process is automated. Simply roll your bike into the groove, enter your payment, and your bike is taken underground by a robot arm. To retrieve your bike, just wave your ticket. Genius!
