In this mini-course, I will discuss what I consider to be the current issues in the analysis of three phenomena in Japanese: scrambling, omplex-predicate formation, and ellipsis. For scrambling, I will briefly present the analysis proposed in Saito 2003, and try to extend it to account for wh and quantifier scope. One consequence will be that the scope of those elements are determined derivationally. Similarly, I will take the movement analysis of complex predicates in Saito 2001 as the starting point, and apply it to the classical cases of complex predicates in Japanese, passives and causatives. Finally, I will consider the recent arguments for and against Soowon Kim and Satoshi Oku's DP ellipsis hypothesis. The discussion on each topic will be open-ended in the sense that we will have more problems (research topics) than solutions at the end.
