Especially when it comes to reliability. Imagine receiving a note from the rail line operator stating that the train was late to give to your employer...

4:18 A little bit resemblance to the Philippine's LRT 1 (Yellow line color), and LRT 2 (Orange line color), but their Japanese train counterpart is much longer in length. Why is that so? Japan, thru its JICA, gave technical assistance to the Philippines in the building and development of the train system. I don't know what is the name of the Line (that one in Yellow and Orange color)? Of course the red one is the Marunouchi Line. By the way, the name "Ochanomizu" station reminds me of a long-nose scientist who takes care of "ATOM" in the Astroboy series.
That's GTO-chopper sound, not inverter sound. It's very unique system using separately-excited DC motor, emits sound like violin at accelerating or regenerative braking.
