今回は、日本史の常識を覆す「旧石器時代」の真実に迫ります！

戦前までは「縄文時代以前の日本列島には人は住んでいなかった」というのが定説でした。しかし、群馬県・岩宿遺跡でアマチュア研究家の相沢忠洋氏が「打製石器」を発見したことで、日本の旧石器時代の存在が証明され、歴史の教科書が大きく書き換わりました。

実は、当時の人々はただマンモスやナウマンゾウなどの大型動物を追うだけの原始的な生活を送っていたわけではありません。遺跡から出土した「黒曜石」の謎を紐解いていくと、私たちが学校の授業で習うイメージを遥かに超えた、驚くべき先祖たちの技術力と活動範囲が浮かび上がってきます。

氷河期の過酷な気候環境や、黒曜石・石器作りの高度な技術に秘められた、私たちの先祖の知性に迫ります。歴史好き必聴のエピソードです。ぜひ最後までお聴きください！

[Episode Description]

In this episode, we challenge common knowledge about Japanese history and dive deep into the truth of the Paleolithic period (the Stone Age)!

Before World War II, it was widely believed that no humans lived in the Japanese archipelago before the Jomon period. However, this historical assumption was completely overturned when Tadahiro Aizawa, an amateur archaeologist, discovered knapped stone tools at the Iwajuku site in Gunma Prefecture. This breakthrough proved the existence of Japan’s Paleolithic era and rewrote the history textbooks.

In reality, the people of this era were not just primitive hunters chasing after giant mammals like mammoths and Naumann's elephants. By uncovering the mysteries of "obsidian" (volcanic glass) found at these sites, we reveal the incredible technological skills and massive mobility of our ancestors—far beyond what we were taught in school.

Join us as we explore the intelligence of our ancestors, hidden within their advanced stone-tool craftsmanship and survival skills during the harsh Ice Age. This is a must-listen episode for all history lovers. Enjoy the show until the very end!
