In 3 days ~40% in a week ~70%
Hyalessa maculaticollis is a species of cicada found in Northeast Asia in the order Hemiptera. Regarding the classification, the genus of the species was changed from Hyalessa to Oncotympana because of its difference from the species found in the Philippines.
In Japan, the name of this cicada is derived from the sound it makes. It is known as minminzemi (ミンミンゼミ, literally, minmin cicada) because of its well-known male song that sounds like 'mi—n, minminminminmi...' (Japanese: ミーンミンミンミンミンミー...).
In Korea, it has the name chammaemi (참매미) (literally 'true cicada' or 'common cicada'), indicating the commonality of this species in Korea. In China, it is called diāo liáo (蛁蟟). Hyalessa maculaticollis is found in China, Japan, the Korean Peninsula and maritime areas of Russia. Individuals in Korea, Eastern China and Far East Russia were considered to be Hyalessa fuscata (Distant, 1905) but recent taxonomic data shows H. fuscata is a synonym of H. maculaticollis.
In Japan, they are distributed from the Oshima Peninsula in southern Hokkaido to Honshu, Kyushu, and their surrounding islands (Tsushima, Koshiki Islands). Their distribution is limited by the... Wikipedia →

Possible
About 20% of wildlife watchers report a Robust Cicada sighting in Tokyo on a given day, based on 688 verified sightings from GBIF citizen-science data. It is the 22nd most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report a Robust Cicada in Tokyo on a given day, against under 5% in November to June, the lowest months.
5th of 8
Of the 8 cities where we can rate Robust Cicada sightings, Tokyo ranks 5th at about 20%. The best odds are in Daegu (South Korea, about 30%), Seoul (South Korea, about 30%) and Sendai (Japan, about 30%).
Same family: Cicadidae
The closest relatives of the Robust Cicada that you can see in Tokyo (family Cicadidae, Typical Cicadas) are Large Brown Cicada (about 30%), Kaempfer Cicada (about 20%) and Black Giant Cicada (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Robust Cicada is recorded against all the insects logged in Tokyo (688 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.
