Acrida cinerea
In 3 days ~50% in a week ~80%
Acrida cinerea, sometimes called the Oriental longheaded grasshopper/locust or the Chinese grasshopper though this name is also applied to Oxya chinensis, is a member of the Acrididae family. Like other members of the genus Acrida, Acrida cinerea lacks stridulatory organs on its legs and so they do not make noise while moving.
Acrida cinerea, like other Acrida species, is a pest of many agricultural crops. It is found throughout China, Korea, Japan, South East Asia and Indonesia. Historically it has been used as a human food source, and it has been investigated for its nutritional value for the poultry industry. Wikipedia →

Possible
About 20% of wildlife watchers report an Oriental Longheaded Locust sighting in Osaka on a given day, based on 162 verified sightings from GBIF citizen-science data. It is the 11th most-seen of the 352 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July and August
In those months about 40% of wildlife watchers report an Oriental Longheaded Locust in Osaka on a given day, against under 5% in December to April, the lowest months.
5th of 15
Of the 15 cities where we can rate Oriental Longheaded Locust sightings, Osaka ranks 5th at about 20%. The best odds are in Nagoya (Japan, about 40%), Daejeon (South Korea, about 30%) and Daegu (South Korea, about 30%).
Same family: Acrididae
The closest relatives of the Oriental Longheaded Locust that you can see in Osaka (family Acrididae, Short-horned Grasshoppers) are Slender Green-Winged Grasshopper (about 20%), Patanga japonica (about 20%) and Carinate Locust (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Oriental Longheaded Locust is recorded against all the insects logged in Osaka (162 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.
