コオロギが鳴いている。 （こおろぎがないている。） koorogi ga naite iru. In English, we say "crickets" when there is almost total silence. For example, in a classroom, if the teacher says something controversial and a student says, "Oh yeah, well, what about...?" If the teacher doesn't respond immediately, during the long pause preceding the teacher's answer, someone could say, "crickets" which means it's so quiet the only sound you can hear is the crickets chirping. Crickets chirp during the day, but everything is so noisy we don't generally hear them. At night, when the world rests, then we can hear them chirp. OK, Nihongo Hiroba, don't be a cricket!
