This book offers an up-to-date and comprehensive reference to Japanese law with a primary focus on private law, including commercial and business-related laws such as corporate law, contract law, and competition law. It also covers a wide range of related topics, such as the protection of human rights, systems of dispute settlement, and criminal law and procedure. Fully updated and revised, this fourth edition expands on the major reforms and substantial changes Japanese law has gone through since the 1990s and analyses the successes and failures of implemented changes in light of developments since the third edition (2009), by referring to new amendments, judgements, and Supreme Court cases. Providing clear guidance and detailed analysis to help demystify Japanese law, this book is an essential reference work for all who have an interest in Japanese law.
