Observing the city of Pusan from the airplane, we can see many mountains.
It looks like Kansai in Japan.
Pusan is the second largest city in Korea with a population of about 3.5 million.
If a city has more than 3 million people, it must be a big city having a professional baseball team or a good museum.
Pusan has been having connection with Japan from ancient times because of its short distance.
