The Kamifukami dialect spoken in Yatsushiro, Kumamoto, has a two-pattern accent system. Among the two-pattern accent systems in Kyushu, bunsetsu obligatorily serves as an accentual unit and, except in a few cases, the “expansion of an accentual unit,” where a single accent pattern spans over two or more bunsetsu, has not been observed. However, this study reveals that the Kamifukami dialect exhibits the expansion of an accentual unit in a wider range of environments than other dialects. It also confirms that a two-pattern system in this dialect is typologically unusual because bunsetsu does not necessarily function as an accentual unit.
