Korea is generally more temperate than SE Asia. Hot and humid in the summer (when most annual rainfall occurs), cold and dry in the winter. The picture in this article shows a rice paddy in South Korea in June. Seems like it would be Irrigated in ASL terms.

Arable land in small alluvial flats of most rural river valleys in South Korea are dedicated to paddy-field farming. Farmers assess paddy fields for any necessary repairs in February. Fields may be rebuilt, and
bund breaches are repaired. This work is carried out until mid-March, when warmer spring weather allows the farmer to buy or grow rice seedlings. They are transplanted (usually by
rice transplanter) from the indoors into freshly flooded paddy fields in May. Farmers tend and weed their paddy fields through the summer until around the time of
Chuseok, a traditional holiday held on 15 August of the
Lunar Calendar (circa mid-September by Solar Calendar). The harvest begins in October. Coordinating the harvest can be challenging because many Korean farmers have small paddy fields in a number of locations around their villages, and modern harvesting machines are sometimes shared between extended family members. Farmers usually dry the harvested grains in the sun before bringing them to market.
The Chinese (or
Sino-Korean) character for 'field',
jeon (
Hangul: 전;
Hanja: 田), is found in some place names, especially small farming townships and villages. However, the specific Korean term for 'paddy' is a purely Korean word, "non" (
Hangul: 논).
