It is a day-flying species. There are two generations per year, with adults on wing from early June to mid July and again from mid August to mid September.
The larvae feed on the leaves of Trifolium repens, Taraxacum species, Equisetum arvense and Typha angustifolia. They are known to eat dead leaves as well as living tissue. Wikipedia →

Rare
Under 5% of wildlife watchers report a Japanese Nine-Spotted Moth sighting in Seoul on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 460th most-seen of the 525 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 August
In those months about 10% of wildlife watchers report a Japanese Nine-Spotted Moth in Seoul on a given day, against under 5% in July and September–May, the lowest months. Those are among Seoul's wettest months, with about 190 mm of rain a month against 20 mm in January.
7th of 7
Of the 7 cities where we can rate Japanese Nine-Spotted Moth sightings, Seoul ranks 7th at under 5%. The best odds are in Sendai (Japan, about 20%), Nagoya (Japan, about 20%) and Osaka (Japan, about 10%).
Same family: Erebidae
The closest relatives of the Japanese Nine-Spotted Moth that you can see in Seoul (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Fall Webworm Moth (about 20%), Spongy Moth (about 10%) and Kidokuga piperita (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Japanese Nine-Spotted Moth is recorded against all the insects logged in Seoul (5 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.
