Possible
About 20% of wildlife watchers report a Chestnut Tiger sighting in Nikko National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 36th most-seen of the 86 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July–August and October
In those months about 30% of wildlife watchers report a Chestnut Tiger in Nikko National Park on a given day, against under 5% in March–May, September and November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Chestnut Tiger is recorded against all the insects logged in Nikko National Park (6 verified sightings from 2019 to 2026), 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.
