Isu Station

Close

This is a transit station on Line 4 that connects Gangbuk and Suwon-Uiwang-Gwacheon from Seoul's southern central point and through Gangnam, connecting Gangseo to the northeastern part of Seoul. Of course, there are many floating populations and a complicated subway transfer station. The transit route is very long, so the transit environment is not very good. You have to walk a lot. Aladdin's second-hand bookstore on the upper platform of line 4 is where young people and a small number of homeless people come to know the road.
