Hi, Constantine!
This appears to be a species of Angustassiminea, possibly A. castanea (Westerlund, 1883). It's distributed from Japan to Taiwan, including Korea and the China coast, and is our most common assimineid. However, you mentioned that it was an alien species, so this may be a possibility.
Regards,
Ron

Dear Listers,
Despite its

this ubiquitous
American landsnail, Punctum minutissimum, can move
