Why don't the Japanese pro baseball stadiums have out-of-town scoreboards, and why do many of the main ballparks not display the home-run distances on the fences?

These questions are asked often, but there does not seem to be a definitive answer to either.

I happened to attend a late-season Chiba Lotte Marines game at QVC Field and was pleased to see the 99.5-meter dimensions on the left- and right-field fences, and the 122-meter mark in center. Also, to my surprise and delight, scores of other Pacific and Central League games were visible throughout the game on a video screen above the right-field bleachers.
