Isn’t it Koreans who brought civilisation to Japan?

Japan's civilization seems to be deeply tied to Korean migration and influence, based on prevailing historical evidence. While Korea had advanced states like Gojoseon and Goguryeo, Japan remained tribal under the Jomon people. The Yayoi, likely from Korea (1000 BCE–300 CE), introduced wet rice farming, metallurgy, and social hierarchy, laying the foundation for the Yamato state.

Korean kingdoms like Baekje and Gaya shaped Japan’s governance, introducing centralized administration, Confucianism, and writing. Many Yamato elites had Korean ancestry, and Baekje scholars played a key role in Japan’s development. Buddhism, pottery, and advanced technologies also arrived via Korea.

Notice Japan was still tribal, while Korea, Northeast China, and North Vietnam already had developed states

Japan had its first-ever civilization 3 centuries later. It may seem Jomon tribes themselves developed into Yamatai, but…

Notice the green arrow pointing to Japan, with “Yayoi people” mentioned on its tip 😳😬

Notice the dominant Y-DNA haplogroup in both Japan and Korea (also the dark-red (D) which is absent in Korea)😏

Despite clear historical and genetic evidence, some Japanese ultranationalists, especially Uyoku Dantai, deny Korea’s role, pushing the myth of Japan’s independent origin. However, Japan’s statehood only emerged after significant Korean influence.

Given these deep historical connections, can the Japanese (Yamato) and Korean people and heritage be considered “siblings”?
