The power grid in Japan runs at 50hz in half the country and 60hz in the other half.

    i'm real. I just wanted to make a point that "59.94Hz is such a weird number. Isn't the power grid running at 30Hz and TVs used to double it?" They don't double it, it was in fact running at 60hz or 50hz depending where you lived.
