T. j. ishigakiana Distant, 1892
Tanna japonensis, also called the evening cicada or higurashi (Japanese: 蜩, 茅蜩, ひぐらし?), is a species of cicada, a family of insects, and a member of the genus Tanna. It is distributed throughout East Asia, and is most common in Japan. Its shrill call can be heard most often in the morning and evening.
The adult male has a body length of 28–38 mm (1.1–1.5 in), the female is 21–25 mm (0.8–1.0 in). The male's abdomen is longer and thicker than that of the female, making it easy to distinguish between them. In addition, the intra-abdominal cavity of the male is more developed, giving it a more resonant call.
In Japan, their habitat ranges from temperate Hokkaidō in the far north to subtropical Amami Ōshima, close to Taiwan (variants and subspecies, such as T. j. ishigakiana), and live in a wide range of habitats. Outside of Japan, they live throughout China. They also were believed to have lived in the Korean peninsula, but this was a clerical error. They live in the cypress, cedar, and hardwood forests, from the mountainous regions in Hokkaido to the plains of northern Kyūshū, and even in southern Kyūshū, they can be found in slightly higher mountain elevations.

The peak time for hearing T. japonensis is autumn, but they can also be heard at the end of summer in some regions. From September until mid-October, their calls can be heard almost every day.
The males call with a distinctive, melancholy sound. This occurs before sunrise, and they often sing at twilight or after sunset, in dusk, when the temperature has dropped, or when it becomes cloudy. The call changes with temperature, being correlated with the firing rate of the tymbal nerve.
In Japan, the sound is popularly associated with melancholy, and it has been the subject of literature, and television shows, such as "Summer Evening" and Higurashi no Naku Koro ni (ひぐらしのなく頃に?, lit. When the Cicadas Cry), feature it as a sound effect or a plot point. Their calls are quite loud, but do not carry well over distance.
