With luck
About 10% of wildlife watchers report a Japanese Peacock Swallowtail sighting in Tokyo on a given day, based on 87 verified sightings from GBIF citizen-science data. It is the 162nd most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April to September
In those months about 10% of wildlife watchers report a Japanese Peacock Swallowtail in Tokyo on a given day, against under 5% in October to March, the lowest months.
Among the best

GBIF citizen-science records
It is estimated from how often the Japanese Peacock Swallowtail is recorded against all the insects logged in Tokyo (87 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.
