Tanna japonensis, also called the evening cicada or higurashi (Japanese: 日暮, 蜩, 茅蜩, ひぐらし, ヒグラシ), 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.
One of its possible kanji names (茅蜩) is derived from the character (茅) for a category of grasses that includes Miscanthus sinensis, a type of reed that it inhabits. In Japan, it is also known as kanakana (カナカナ) because of the noise that it makes.
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.
The body is coloured reddish-brown with green around the compound eye and in the centre and back of the thorax; mountain dwelling specimens tend to be darker. In Japan, their habitat ranges from temperate Hokkaido in the far north to subtropical Amami Ōshima, close to Taiwan (variants and subspecies... Wikipedia →

With luck
About 10% of wildlife watchers report an Evening Cicada sighting in Sendai on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 56th most-seen of the 128 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Evening Cicada is recorded against all the insects logged in Sendai (10 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
