Possible
About 20% of wildlife watchers report a Patanga japonica sighting in Osaka on a given day, based on 82 verified sightings from GBIF citizen-science data. It is the 26th most-seen of the 352 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.

Same family: Acrididae

GBIF citizen-science records
It is estimated from how often the Patanga japonica is recorded against all the insects logged in Osaka (82 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.
