In the Fukuoka dialect, flat high pitch spreads between a WH-word and a [+WH] COMP which binds it. Two assumptions are made to explain this phenomenon: (i) there is a rule which forms a phonological phrase between a WH-word and a [+WH] COMP, (ii) only the underlying accent of lexical head will surface. These assumptions also hold for the Pusan dialect of Korean, which shows striking similarity to Fukuoka Japanese.
