Wow, I figured you had ventured off into hyperbole land but first thing I see in that matterport is a toilet separated from the main living space by a curtain.... a crapper curtain. Down with human dignity!
This was my only real gripe, to be honest. In an American context I can understand that this is a tight space for someone likely pulling in high five figures. But by Japanese standards, if you gave the WC a pocket door, you'd have a decent 1LDK that would run for about USD 1200-1500 a month (in Tokyo).
