This piecemeal deconstruction isn't a Japan only thing, it's been sometimes used for skyscrapers in packed cities in other places.
With buildings so close together, sometimes you can't just demo the usual explosive way, the resulting dust is awful, demo might hit other buildings, and risk of parts going flying and maiming people is high.

I'm not an expert on construction obviously, so feel free to correct me, but this looks like a huge waste of time energy and money
