Rare
Under 5% of wildlife watchers report a Lasius japonicus sighting in Tokyo on a given day, based on 40 verified sightings from GBIF citizen-science data. It is the 284th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May to July

GBIF citizen-science records
It is estimated from how often the Lasius japonicus is recorded against all the insects logged in Tokyo (40 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.
