Asadal is derived from the words "Asa" meaning "morning" and "dal" meaning "land". The creation of the word dates back to 2333 B.C. and is known to originate from the myth of Korea's father "Dan-gun".
He became the king of all Korea and created his kingdom "Chosum". He established his capital city at "Asadal", now Pyongyang and ruled his land for 1,500 years.
