6349 Acapulco           Discovered 1995 Feb. 8 by M. Koishikawa at the Ayashi Station of the Sendai Astronomical Observatory.
Named for the city in Mexico, Acapulco is the international sister city of Sendai, Japan, affiliated since 1973. Acapulco is a famous resort and well known as one of the three most beautiful ports in the world. Hasekura Tsunenaga, the retainer of the famous Japanese feudal lord Date Masamune, made a stop there after he crossed the Pacific Ocean on his way to Rome.
