The second sound is the buzzing of cicadas. In Japan, when summer arrives cicadas are terribly noisy, shrilling all day from morning till night, and are almost everywhere. Most Japanese, especially men, likely have caught cicadas or collected cicada shells during their childhood. There are about 30 kinds of cicadas in Japan, but only about 10 of them are the ones we can often hear chirping. I came to the U.S. two years ago, but I very rarely hear them. It seems that there are cicadas in the United States, but they’re often in forests away from people.
