Educational Manga Supervised by the National Astronomical Observatory of Japan Released

KADOKAWA Corporation released 'Kadokawa Manga Science Series: Science of Stars and the Universe - Avert the Crisis on Earth!' (Original Concept/Supervision: National Astronomical Observatory of Japan, Art: Hako Matsuura) on May 27, 2026.

### Learning Calendar Mechanics Scientifically This book is an educational manga that unravels questions about the calendar, such as 'Why is a year 365 days?' and 'Why do seasons change?', by explaining the movements of the Sun, Earth, and Moon. The National Astronomical Observatory of Japan's official character, 'Honoka,' leads the narrative.

### Appeal as a Fantasy Adventure The story takes place in 'Astera,' an alternate world where the concept of the calendar has been forgotten. The protagonist, Daiki, gets lost in this world and faces a crisis that threatens both Earth and Astera, creating a dramatic narrative that allows readers to learn about the mechanics of the universe naturally.

### Key Highlights - Natural engagement with difficult themes through characters. - Enjoyable as a pure story with unpredictable plot twists. - Making the study of the universe relatable by focusing on the familiar daily calendar.
