The Silent Launching Pad: How the ancient Japanese “Sodai” (Era) /”Sojin” (People) Rewrites the Peopling of the Americas

Executive Summary

Global academic discourse regarding the “First Americans” remains bottlenecked by a Eurocentric, Siberian-centric paradigm that overemphasizes the inland Mammoth Hunter lineage (Ancient North Eurasian / ANA) and the Clovis-First model. Furthermore, Western understanding of Japan’s deep past rarely looks beyond the Jomon period (approx. 16,500 years ago).

This report presents a disruptive, multi-wave migration framework proving that the true pioneers of the New World were maritime populations originating from the Japanese Paleolithic—the Sodai (祖代) / Sojin (祖人) era—who utilized the Kelp Highway via a unique Migration along Pacific Ocean Rim (MPOR).

1. The Three-Wave Stratified Migration Framework

The initial peopling of the Americas cannot be attributed to a single, monolithic inland migration. Archaeological and technological typologies dictate a clear three-stage stratification:

[Wave 0: Zero Wave]  ➡  South America Deep Stratum (Population-Y/Coastal People as like Hokkaido Sojin) / Primitive Lithic Typology A

[Wave 1: First Wave] ➡  North American Coastal Pioneers (OAM/Hokkaido Sojin)   / Advanced Lithic Typology B

[Wave 2: Subsequent Wave] ➡  Inland Mammoth Hunters (Siberian ANA)   / Clovis Fluted Typology C

The inland Mammoth Hunters, long celebrated by Western academia as the “First Americans,” were actually a later, subsequent wave. They did not discover an empty continent; they arrived to find a land already settled by coastal predecessors.

2. The Izu-Sodai Mariners & The PAHK Gateway

The technological blueprint for New World maritime migration was perfected 38,000 years ago in the Izu Archipelago of Japan.

• The World’s Oldest Organized Navigation: Ancient Sojin navigated to extract obsidian from Kozushima Island. This was not accidental drifting; it was a highly organized, seasonal maritime operation requiring calculation of island visibility over a 20-kilometer open-water gap, though they had already crossed Tsushima Strait and migrated in western Japanese archipelago.
• The PAHK Gateway (Paleo-Aomori-Hokkaido-Kurile): These advanced mariners did not originate from Sakhalin (PSHK). Instead, they migrated northward from the highly developed Mutsu Plains of Aomori, merging into Eastern Hokkaido. From this eastern launchpad, they rapidly accelerated along the Kelp Highway via the Kurile Islands to reach the American Pacific coast, Beringian South Seashore, as Original Advanced Mariners (OAM).

3. Resolving the Genetic Mystery: Population-Y and the MPOR Theory

Harvard Medical School’s groundbreaking discovery of an Australasian genetic signal (Population-Y / Onge / Aboriginal Australian affinity類縁性) in the deep indigenous strata of South America (such as Amazonian and Patagonian tribes) has left mainstream scholars baffled. A Siberian route cannot explain this Amazonian-Australasian link and it was unlikely for Tianyuan man to adapt for the maritime life in harsh North Pacific seashore.

The Maritime Pacific Rim Origin Route (MPOR) flawlessly resolves this enigma:

1. The Sundaland Outflow: During the Last Glacial Period, ancestral populations related to the Andamanese (Onge) and Australasians moved northward along the now-submerged continental shelves had migrated along coast to north and dispersed clockwise along coast of the Akebono Sea (曙海) (comprising the modern Yellow Sea, Bohai Sea, and East China Sea) to Northern Kyusyu.
2. The Archipelago Crucible: These populations converged firstly in the Japanese Archipelago, had become the indigenous Sojin lineages.
3. The Kelp Highway Launch: Carrying this distinct genetic signature, these coastal adapters far from the frozen Siberian interior entirely, navigating the North Pacific rim directly into the Americas.

Conclusion: A Call for Global Paradigm Shift

The Jomon culture did not emerge from a vacuum; it was built upon the 40,000-year-old technological and maritime foundation of the Sodai Era changing the terminology to Jomon after the appearance of pottery.

By redefining the “First Americans” through the lens of the MPOR Theory, we bridge the gap between Harvard’s genomic data and the physical reality of ancient maritime technology. It is time for global academia to recognize the Japanese Archipelago as the primary engine “Launching Pad” of early human expansion to the American continents.
