With luck
About 10% of wildlife watchers report a Japanese Stag Beetle sighting in Osaka on a given day, based on 49 verified sightings from GBIF citizen-science data. It is the 66th most-seen of the 352 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.
June to August
In those months about 20% of wildlife watchers report a Japanese Stag Beetle in Osaka on a given day, against under 5% in October to May, the lowest months. Those are among Osaka's wettest months, with about 180 mm of rain a month against 55 mm in January.

GBIF citizen-science records
It is estimated from how often the Japanese Stag Beetle is recorded against all the insects logged in Osaka (49 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.
