The casino closed at midnight local time today (8 December), but the operator did not indicate when the facility would be permitted to reopen.
Kangwon Land was forced to shut the casino after the government increased its Covid-19 regulations to the second stage in the Gangwon and Jeongseongun provinces.
This marks the third time this year that the casino has had to close due to Covid-19 measures.
Kangwon Land first temporarily shut its doors on 23 February and was not able to reopen until 1 July. However, the site closed again for a period in late August and had only been able to operate at limited capacity since October.
Last month, Kangwon Land posted an 81.1% decline in revenue to KRW76.62bn (£52.5m/€57.9m/$70.2m) in the third quarter, as well as a KRW40.3bn loss, as closures of its venues lasted longer than expected.
Venues were closed to the general public for part of the quarter and only open in a limited capacity for the remainder of the period.
