Summers and Bug-Catching
If you've ever played through The Legend of Zelda: A Link to the Past, or Pokemon Red and Blue, you may've come across the eponymous bug-catching net.
I recall this didn't make a lot of sense to me, but I mostly just went with it.
Having experienced a summer in Japan, it has suddenly made sense to me. In Japan, the telltale sign that summer has officially begun is hearing the annual cries of cicadas. You can hear the sounds in just about any anime series as well. It's extremely loud and constant for several weeks into summer. To Japan, the sound is endearing.
Cicadas, once above ground, have a very short 1-2 week lifespan, and a favorite passtime here is catching these bugs in nets to place inside jars.
Certainly, this isn't nearly as much of a thing in in the west. But I suppose there was no easy way to translate this concept, and so it was just kept in the games as-is.
