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 Tokyo on a given day, based on 916 verified sightings from GBIF citizen-science data. It is the 13th most-seen of the 1013 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.
August
In that month about 40% of wildlife watchers report an Oriental Longheaded Locust in Tokyo on a given day, against under 5% in November to April, the lowest months.
7th of 15
Of the 15 cities where we can rate Oriental Longheaded Locust sightings, Tokyo ranks 7th 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 Tokyo (family Acrididae, Short-horned Grasshoppers) are Patanga japonica (about 10%), Carinate Locust (about 10%) and Migratory 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 Tokyo (916 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.
