Conclusion: Oi river valley occupation group at 46%.
• Koi fish likely named at 38%.
Population climbs through to 36%.

At 35% Some cataclysm occurs resulting in cultural development collapse, while alphabet continues to develop. This might be the previously identified event that disperses population away from the Fuji River region.

At 30% Growth in population returns.
• Sake likely invented at 20%
• Kanji likely formalized at 8%.
Growth remains remains high until it drops to near zero at <1%.

You will notice that just like in Korean and Chinese family names, Q, V, and X fall in the 0% section. So it looks more like these phonetic objects are not in use regionally. And insufficient cultural input exists to introduce them. Roman Contact might have eventually introduced them, but the Roman civilization collapsed.
