It is all a far cry from its history, although there are distinct parallels.
The city became known around the world in 1950 when American General Douglas MacArthur led United Nations forces in a landing behind enemy lines.
A statue of MacArthur stands in Freedom Park, Korea's first western-style park.
Now the majority of visitors to the country who land here come through Incheon International Airport.
The city is a hub for all things: passengers, transporters, cargo - you name it, it passes through Incheon.
But there is more to the city than the sprawling modernity of the 21st century and the coming and going of people and trade.
There are a host of Joseon Dynasty buildings, including Incheon Dohobucheongsa, a local magistrates' office, and Hyanggyo, a Confucian school.
Further afield, Incheon is surrounded by popular island resorts including Yeongjong, Jakyak and Wolmi islands which boast superb beaches.
Eulwangi beach and Seopri beach, on Deokjeokdo, are two of the best and boats there leave from Yeon-an Pier.
And as you would expect, any city on the sea also has a wealth of seafood restaurants.
Tourist boats go out from the pier, and fishing boats come in.
