The “Jomon period” (縄文時代), a historical era unique to Japan, remains largely shrouded in mystery, yet its characteristics continue to profoundly influence contemporary Japanese people. Personally, from the time I began independently researching Japan eight years ago, I became most deeply engrossed in investigating the Jomon period. Today, my research extends beyond the Jomon era, delving deeply into the subsequent “Yayoi period” (弥生時代) based on my comprehensive understanding of Japan’s deeper history.
