History 
The name and a logotype was published on October 26, 2005 as a result of public contest. The use of the name started on March 27, 2006 when the Kintetsu Higashi-Osaka Line was extended to Gakken Nara-Tomigaoka Station and renamed the Keihanna Line. Etymology 
The term "Yumehanna" can be broken into "Yume" and "Hanna"; "Yume" means dream in Japanese and "Hanna" (阪奈) is a kanji abbreviation for Osaka (大阪) and Nara (奈良). The committee for the name selection explained the reason for the victory of the name as follows: "It successfully expresses the hope for the future of the connection of the Science City and the Osaka Bay Area. Also, the use of hiragana creates the soft nuance of the word and a friendly image." References
