I'm a bit worried that this comes across as an advert. It's not — I reached out to the team at GIKEN, they had no editorial control, and no money changed hands. (Although they did, of course, go through all the paperwork required to let me climb into their giant robot parking garage.) They also asked me to include this: “Eco Cycle and Eco Park are brand names of GIKEN LTD. in Japan”, which seemed a reasonable enough request.
