The script on the signs is clearly Korean, and the traffic speed limit sign (30) and road markings are typical of South Korea. The architecture features a mix of modern high-rise glass towers and older, smaller commercial buildings, which is very characteristic of Seoul. I see a yellow speed bump sign, common in residential or school zones in the country. The overall urban layout and the style of the paving suggest a developed area in a major Korean city. I am quite confident this is in Seoul.

Country: South Korea, City: Seoul
