萬川集海

"Although the author of the Bansenshukai was influenced by Chinese thought, and even indicates a connection to Chinese military traditions, he presents the material as the ultimate accumulation and perfection of Ninjutsu knowledge--as the name Bansenshukai itself suggests."

There is little doubt to me now there are deep connection between Babylon and the far east. Cuneiform writing lead to kanji, sumerian wrestling to summo, there is even a form of Japanese writing identical to the Hebrew one. The Japanese main god is also a goddess. 8 corner star appears in many of their symbols. But they are coming back to us.

Make way...
