(The subtitles include translations of the Japanese dialogue. Also, I'm sure the company is putting on a bit of a show because they're being filmed, but regardless.)
The thing I think is fascinating about this video is how many of the comments are "oh wow, Japanese movers are so precise, so considerate, they work so hard"
and how few put together the pieces that they can do this because there's about eight people working on this move! These movers aren't individually packing each dish because they're of staunch moral character, but because they have time to do it! When I moved in the US, the moving company sent two guys and they weren't lazy, they did as much as two people could reasonably do! Which is 1/4th as much!
And having never been to Japan I don't want to make sweeping statements about how it actually works there, like I said I doubt this is a typical or low-budget experience, but this is not the only video I've seen of "hard work" that was secretly a video of adequate staffing.
Here's another one! So many comments about how US kids eat processed junk, so few noticing that US school kitchens don't have big rows of people washing and chopping vegetables!
Japan made it a political and financial priority to provide decent school lunches, and the US didn't. It's so frustrating seeing people try to take that down to the individual level with comments amounting to "American kids only want to eat pizza because they are inferior in character."
(have you eaten US public school pizza? trust me, nobody with options wants that)
