As a special example, there is a case in which Sendai City in Kagoshima Prefecture became Satsumasendai City by attaching the old provincial name of Satsuma to Sendai which was homophony of Sendai City in Miyagi Prefecture although the Chinese characters that make up the word is different from that of Sendai in Miyagi Prefecture; this city name was created at the time of merger (the nearby local governments disliked the image of incorporated merger and this was one reason why Sendai City became Satsumasendai City).
また、特殊な例としては鹿児島県の川内市が宮城県の仙台市と同音の「せんだい」であったことから合併に際して旧国名を冠し薩摩川内市となった事例がある（周辺自治体が編入合併のイメージを嫌ったことも理由）。
