Rare
Under 5% of wildlife watchers report a Miyama Stag Beetle sighting in Tokyo on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 644th 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 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Miyama Stag Beetle in Tokyo on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Miyama Stag Beetle sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
3rd of 3
Of the 3 cities where we can rate Miyama Stag Beetle sightings, Tokyo ranks 3rd at under 5%. The best odds are in Sendai (Japan, about 10%) and Osaka (Japan, about 10%).

GBIF citizen-science records
It is estimated from how often the Miyama Stag Beetle is recorded against all the insects logged in Tokyo (11 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.
