In Tokyo they had a Stranger Things themed restaurant for a while. Pop up culture is pretty big in Japan so it worked out great I suppose. I don’t expect it to work in other places nearly as well. Especially if it’s a permanent structure.
I have an Amazon echo that is a glorified weather reporter and cooking assistant. It’s pretty useful for setting timers and for calculating conversions for measurements. I also use it as a white noise machine for bed time.
I do get the random interruptions where it some how responds to some random conversation I am having and I promptly cuss it out. It’s probably foolish for my privacy, but I don’t actively plan crimes in front of it, but who knows how it might bite me in the ass in the future.
There’s a surprising amount of green for major cities that otherwise look like concrete jungles. There’s usually plenty of parks and kids are in general very safe. Maybe this is just my comparison from originally living in the states, but it is super safe for children and the amount of expected unsupervised travel kids do in Japan is astonishing.
