why are some japanese monster movies from the showa era tear jerkers in the end ?

3. I recently watched Raiga,

which is a spoof of monster movies. I was amazed when I saw the location, because I was very familiar with it-- the Asakusa district of Tokyo. Raiga rises out of the Sumida River and starts knocking stuff around-- including the giant golden "hop" on top of the Asahi Beer building. In fact, he knocks it up in the air and it lands across the river, right in front of the entrance to Asakusa Station, which I used at one time in my commute. Then these two guys who are obviously tourists walk out of the station, and one of them points to the "hop" and says, "What's that?" The other one replies, "Monster doo-doo, what else?"
