This chapter deals with null pronouns in Japanese (henceforth, Japanese pro). It is argued that Japanese pro differs from ordinary pronouns such as in English and behaves like SE anaphors in the sense of Reinhart and Reuland (Linguistic Inquiry 24:657–720, 1993) (R&R) with respect to Condition B effects: it is sensitive to R&R’s Condition B, hence unable to take a coargument as its antecedent, while it is insensitive to R&R’s chain condition due to its [-R] property, namely the lack of ϕ-features. According to the main tenet of the minimalist program, R&R’s chain condition is reformulated under our movement theory of anaphora. It is further argued that the [-R] property of Japanese pro is observed in anaphoric configurations other than those relevant for Condition B effects. It is demonstrated that in those configurations, Japanese pro behaves just like PRO in showing different interpretive possibilities, depending on whether it is locally bound or not. This fact is captured under our movement theory in such a way that locally bound pro forms an A-chain, showing typical [-R] properties, whereas non-locally bound pro forms a heterogeneous chain that includes a null operator-like member, hence showing [+R] properties. Finally, this chapter discusses the Japanese reflexive zibun, with the intention of highlighting the similarities and differences between this reflexive and Japanese pro.
