Those wires between the buildings are peculiarly coloured... They've used black & blue, which would suggest that there's 200V across them, but no neutral (green), required to get 100v. Further, black, blue & green are pole-to-premises colours, not black, red & white like you see in the breaker panel, etc.

So there is no digital terrestrial TV (DVB-T) in Japan?
