Maybe this counts as infrastructure moe. Where else but Japan would a ridiculously non-standard low arch be maintained in a public space with a crazy duct-taped fabric warning people to watch their heads?! It’s so bad, it’s superlative.
Infrastructure moe?
Tokyo Moe 
This is Ueno station, isn’t it?
ochanomizu! i find that platform pleasant. so much green.
Yes! It’s Ochanomizu. I like the view of the Kanda. But aren’t these low arches ridiculous?
Yeah but I always go out of my way to duck under them.
Moe, no? So wrong, yet so inviting!
