## What is SigmaMethod Constitutional Law?

Constitution Memorization is a focused study app designed to help you read the Constitution of Japan and remember its key wording through repeated fill-in-the-blank practice.
The app includes the Preamble and Articles 1 through 103 of the current Constitution. It brings together article reading, 181 fill-in questions, review of difficult material, bookmarks, and visual progress tracking in one simple learning experience.
Whether you have a few minutes during the day or want to prepare intensively before an exam, you can study at your own pace.
【KEY FEATURES】
■ Read the Constitution of Japan
Read the Preamble and Articles 1 through 103, organized by chapter for easy navigation.
Return to the original text whenever you want to confirm an answer, review the context of an article, or reinforce your understanding.
The constitutional text included in the app is based on legal data published through Japan’s e-Gov services.
■ Practice with 181 fill-in questions
Test your memory with 181 questions that hide important words and phrases from the constitutional text.
Think of the missing wording, reveal the answer, and evaluate your own understanding. Actively recalling the text helps reinforce key expressions more effectively than simply reading them repeatedly.
■ Focus on difficult material
After checking an answer, mark the question as mastered or choose to study it again.
Questions you find difficult remain easy to identify, allowing you to spend more time on the articles that need additional attention.
■ Create a personal study list with bookmarks
Bookmark questions and articles that you want to remember or review again.
You can begin a study session using only bookmarked questions, turning your saved items into a focused personal review list.
■ Track your learning progress
Each question is categorized as mastered, in progress, or not yet studied.
A clear progress chart shows how much you have completed and what still requires attention. You can also return directly to difficult articles for additional review.
■ Designed for consistent daily study
The interface is designed to minimize the steps required to begin studying.
Complete a few questions, check the answers, and return to anything you missed. Even short study sessions can build into lasting knowledge when repeated consistently.

・People preparing for qualification or public-service examinations
・University students reviewing constitutional law

・Anyone who wants to revisit difficult articles efficiently
