In this paper, I argue that there is a designated focus position in the CP layer in Japanese and that this position is activated only in limited contexts, such as ellipsis contexts. I argue that in fact one of the best cases for such a designated focus position involves Japanese right dislocation. Assuming the biclausal analysis of this construction, which involves ellipsis, I argue that the postverbal phrase occupies the position in the CP layer designated for a focused phrase. Finally, addressing the question of whether Focus projections can be activated only in root clauses, I investigate what may be called massively pied‐piped cases of Japanese sluicing and demonstrate that Focus projections can be activated by the same types of embedded clauses as Topic projections.

日本右位错在左边缘的焦点许可

在本文中，我认为日语中的CP层中有一个指定的焦点位置，并且该位置仅在有限的上下文（例如省略号上下文）中被激活。我认为，事实上，对于这样一个指定的焦点位置，最好的情况之一就是日本的权利错位。假设这种结构的双月形分析涉及省略号，我认为后动词短语在CP层中指定了针对性短语的位置。最后，针对焦点投影是否只能在根子句中被激活的问题，我研究了所谓的日本流域大口径案例，并演示了焦点投影可以通过与主题投影相同类型的嵌入子句来激活。
