With luck
About 10% of wildlife watchers report a Colias poliographus sighting in Tokyo on a given day, based on 384 verified sightings from GBIF citizen-science data. It is the 43rd most-seen of the 1013 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.
September and October
In those months about 20% of wildlife watchers report a Colias poliographus in Tokyo on a given day, against under 5% in January, the lowest month. Those are among Tokyo's wettest months, with about 230 mm of rain a month against 75 mm in February.

GBIF citizen-science records
It is estimated from how often the Colias poliographus is recorded against all the insects logged in Tokyo (384 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.
