Justice system reform is being implemented in Japan. The number of attorneys ( bengoshi ) has substantially increased and concerns have been raised about the impact on the profession's quality and ethics. The profession has called for a slowdown in the increase. Does the increase really adversely affect legal ethics in Japan? Should the pace of the reform be slowed down, from the perspective of maintaining legal ethics? This paper begins to answer these questions through empirical analysis of (1) whether (...) there is an increase in cases of ethical concerns; and (2) whether such an increase (if any) is caused by the increase in bengoshi . The paper then investigates whether there is an over-supply of bengoshi . It concludes with a discussion of the negative impact that a slowdown of the increase may have on access to justice and the bengoshi profession's (ethical) responsibilities. (shrink)
