Darma, or Dharma, Entered Japan at Least 15 Hundred Years Before to Day

A significant amount of the chinese culture comes out of india. They have absorbed it and made it their own. Then that propagated further east into japan. You will find every single non buddhist hindu deity, divinity, represented in Japane. The consumption of meat was prohibited because of the influence of darma. It is a misconception that the japane are pure buddhists.
