Meihan is a Sino-Japanese pronunciation of two-character kanji acronym for Nagoya and Osaka (名阪). The first character of three-character kanji that represents Nagoya (名古屋) is pronounced as mei, whereas the second character of two-character kanji that represents Osaka (大阪) is pronounced as han.

Construction on the Meihan Expressway began in March 1962, with an intended construction period of only one thousand days. The rapid construction of expressways in Japan at the time was spearheaded by Minister of Construction Ichirō Kōno in preparation for the 1964 Summer Olympics in Tokyo. It was opened as a two-lane expressway in December 1965.^[2]
