New Educational Launch: Manga-Based Rikeinou Puzzle

On November 10, 2025, a new title in the widely successful educational series, Manga de Wakaru! 10-Sai made ni, will be released by Nagaoka Shoten. Co-authored by Keiki Kawashima, the CEO of Wonderfy Inc., and professional puzzle creator Kazuya Yamamoto, this latest edition focuses on 'Rikeinou Puzzles', designed to make learning enjoyable for children aged 10 and under.

With over 1.4 million copies sold, the Manga de Wakaru series combines manga storytelling with educational challenges across various subjects like math, science, and English. Kawashima, known for developing the interactive educational app Think!Think! and several acclaimed puzzle books, brings his expertise to this project. This time, he collaborates with Yamamoto, a seasoned content creator and a representative of Japan in the World Puzzle Championship, ensuring that this new title is both engaging and educational.

Engaging Puzzles for Logical Development

The book features a total of 200 puzzles designed to naturally cultivate the foundational skills of mathematical thinking and scientific problem solving. It includes 192 standard puzzles along with 8 extremely challenging ones. Puzzles are organized in sets of four, allowing for frequent reviews and reflections through fun comic strip explanations that follow each set.

This approach not only promotes intellectual engagement but also offers a sense of accomplishment with every success. Additionally, the book incorporates motivational tools such as 'Daga Shiri' stickers for every four completed puzzles and detective badge stickers at the end of each chapter to encourage continuous learning.

The new publication will also offer gentle explanations for parents throughout the pages, making it a wonderful resource for family learning. This book aims to foster moments of 'thinking time' that are essential for children's cognitive development.
