Likely
About 50% of wildlife watchers report a Black Giant Cicada sighting in Nagoya on a given day, based on 118 verified sightings from GBIF citizen-science data. It is the 3rd most-seen of the 195 insects we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Black Giant Cicada is recorded against all the insects logged in Nagoya (118 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.
