In 3 days ~10% in a week ~20%
Arna pseudoconspersa, the tea tussock moth or Japanese browntail moth, is a moth of the family Erebidae. The species was first described by Embrik Strand in 1914. It is found in Japan, Taiwan, Korea, China, Vietnam and India.
Both the larvae and the adult moths have "hairs" containing toxins that cause rashes, and even dizziness and nausea in humans. It is also a harmful pest. The wingspan is 13–18 mm. The larvae feed on Camellia species. Wikipedia →

Rare
Under 5% of wildlife watchers report a Tea Tussock Moth sighting in Tokyo on a given day, based on 36 verified sightings from GBIF citizen-science data. It is the 309th 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.
June and October–November
In those months about 10% of wildlife watchers report a Tea Tussock Moth in Tokyo on a given day, against under 5% in July–September and December–May, the lowest months.
Yes
Of the 2 cities where we can rate Tea Tussock Moth sightings, Tokyo has the highest daily chance: under 5%. Next come Hong Kong (China, under 5%).
Same family: Erebidae
The closest relatives of the Tea Tussock Moth that you can see in Tokyo (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Japanese Nine-Spotted Moth (about 10%), Ramie Moth (about 10%) and Brown-Striped Semilooper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tea Tussock Moth is recorded against all the insects logged in Tokyo (36 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.
