About this app

This app provides all the preparation you need for the Disaster Prevention Specialist Examination.

It includes a comprehensive analysis of six years' worth of past exam questions, plus original questions, totaling 555 questions. Every question comes with an explanation of "why" each answer choice is correct, ensuring you improve your skills with every practice.

◆ What you can do with this app:

1. 555 questions: Past questions + original questions

Past questions from different years have been reorganized into "topics," and original questions have been added that explore the same topics from different angles. It systematically covers six areas: natural disasters, disaster-related information, disaster countermeasures by public institutions and companies, self-help, mutual assistance, and the Disaster Prevention Specialist system. The year of issue (from Reiwa N onwards) is also clearly indicated for past questions.

2. Illustrated textbook included (2026 edition compatible)

Includes an 11-chapter web textbook explaining "why" things happen. Each chapter features original illustrations, allowing you to deepen your understanding through visual aids. It also supports the latest revisions to the 2026 edition of the Disaster Prevention Specialist Textbook. You can open it in your browser from the button within the app.

3. Explanations that show why the answer is correct

Every question includes a detailed explanation for each option. Because it delves into the reasons for correct and incorrect answers, it helps you retain information through solid understanding rather than rote memorization.

4. Forgetting curve-based review mode

It automatically picks up incorrect and likely-to-be-forgotten questions, allowing you to review them by subject or a mix of all subjects. You can also solve only bookmarked questions.

5. Actual exam-style test mode

Tests of 10, 20, or 30 questions simulate the actual exam to check your abilities. You can also narrow down the questions to specific subjects or create mixed questions focusing on unstudied or difficult questions.

6. Learning analysis

It compiles practiced, incorrect, and likely-to-be-forgotten questions by subject. You can check the stability of your learning and the freshness of your memory with graphs.

7. Motivation-boosting card gacha

Clear tests to get disaster prevention knowledge cards from the gacha. Enjoyable learning is made possible with a collection of 120 images.

8. Daily Question Reminder

Supports the development of a daily study habit.
