Turn the Japanese Civil Code into knowledge you can recall—not just text you have read. Memorize Civil Law is a focused study app designed to help you understand, review, and retain the current provisions of Japan’s Civil Code. Important words and phrases are hidden to create practical cloze exercises, encouraging active recall and helping you identify what you truly remember. The app includes 2,278 questions based on the Civil Code provisions in effect as of June 24, 2026. KEY FEATURES • Learn through active recall Important terms are hidden within each provision. Think of the missing words, reveal the answer, and check your understanding. • Browse the current Civil Code Read provisions in a clean, organized layout that makes the structure of the law easy to follow. • Find provisions quickly Search by article number, heading, or text, and narrow the results by Book. • Save important articles Bookmark provisions you want to revisit and build your own focused review list. • Track your progress See how many provisions you have mastered, which ones are still in progress, and where you need more practice. • Review difficult areas Your learning status helps you return to provisions that require additional attention. BUILT FOR CONSISTENT STUDY Civil law contains a large amount of precise language. Simply rereading it can create the feeling of understanding without reliable recall. By hiding key expressions and asking you to retrieve them from memory, Memorize Civil Law turns each provision into a short, repeatable learning exercise. Whether you are preparing for an examination, reviewing legal fundamentals, or strengthening your knowledge of the Civil Code, the app helps you study efficiently—one provision at a time. Please note: This app is intended for learning and review. It does not provide legal advice and is not a substitute for official legal sources or professional counsel.
