In Japan, commandments were introduced at a comparatively early stage in an incomplete way, so that their significance was not understood fully and they were researched in only a portion of the temples without any Jukai (rituals handing down the precepts).
日本においても比較的初期の段階で戒律が伝えられていたものの、不完全なものでその意義が十分されずに一部の寺院における研究に留まり、授戒の儀式も行われていなかった。
