■ The Iconic 'Gakken no Gakushu' Returns After 16 Years!
Launched in 1946, 'Gakken no Gakushu' was beloved by many children as a comprehensive learning magazine with supplements that allowed them to learn across subjects like social studies, math, Japanese, and arts and crafts. It is being revived for the first time in 16 years since its suspension in 2010. It is reborn as a learning material where craft kits, the magazine, manga, and an online community are integrated, allowing children to learn through experience while moving their hands and expanding their interest in the world.

■ First Installment 'Haniwa no Daikokuho-ten' is a History Starter Kit!
'Haniwa no Daikokuho-ten' is an experiential kit for children encountering history for the first time. Supervised by the Tokyo National Museum, this product allows you to create a small museum at home by assembling the National Treasure Haniwa 'Keiko no Bujin' (Armored Warrior) or polishing magatama from stones. It is a teaching material where you learn by moving your hands, observing, thinking, and summarizing.

■ National Treasure Haniwa Restoration Kit Supervised by the Tokyo National Museum!
The highlight of 'Haniwa no Daikokuho-ten' is the assembly kit that restores the National Treasure Haniwa 'Keiko no Bujin.' The 'Keiko no Bujin' was the first Haniwa to be designated as a National Treasure in Japan and is said to be the masterpiece of Haniwa. The kit was reproduced at a 1/6 scale (approx. 20cm in total length) based on 3D data for research that measured the real National Treasure. With a material containing stone powder, it has a texture and weight like unglazed pottery, giving it a strong presence. By restoring it from parts themselves, children can experience authentic archaeological research.

■ Learning Expanded Through the Magazine, Manga, and Community
The magazine features articles that expand interest in history, such as introductions to the work of archaeological researchers, articles on the experience of building burial mounds, and messages to children encountering history for the first time from Professor Michifumi Isoda. Furthermore, it is linked with the Gakken manga 'Himitsu Series' and the online community 'Asobunda Kenkyujo,' allowing for continuous deepening of learning.

■ Supervision: Tokyo National Museum
The Tokyo National Museum, which opened in 1872 and has the longest history in Japan, supervised the project. The kit's 'Keiko no Bujin' was developed based on high-definition 3D data used for research. In addition, researchers spent time selecting the exhibition works and providing audio commentary, making the content more authentic.
