In this paper I report two kinds of sound changes in Kagoshima dialect. First, I report close vowel's changes, such as [a?] (<aki, 'autumn'), [a?] (<aʒi, 'taste'), [a?] (<abu, 'horsefly'), [a?] (<aku, 'harshness'). These changes, commonly called 'nisshoka', are caused by devoicing final [i] or [u]. Second, I report alveolar's changes in Segami dialect, spoken in Kami-Koshiki island, Kagoshima prefecture, such as [arama] (<atama, 'head'), [abuja] (<abura, 'oil'), [neːzii] (neːzu, 'temperature'), [kuːnu] (<kudzu, 'trash'). In this dialect, these changes occurred very systematically, and so the distinction between /t/, /r/, /c/ and /d/ was not lost after the changes.
