义理是日本社会的基本伦理道德观念,主要有对社会的义理和对名誉的义理两类.通过调查发现义理并非是日本特有的道德观念.中国宋学的义理思想传入日本后逐渐与日本的社会文化相融合,形成了既保持东方本色又带有日本特点的文化现象,成为扎根于日本社会和文化的一种风俗、社会规范.义理与人情并非相互对立的两个概念,而是相互依存不可分割.“,”Righteousness is one of the basic moralities in the Japanese society and can be classified into two types: “righteousness to the society” and “righteousness to reputation”. Related investigation reveals that righteousness is not a morality existing in the Japanese society only. It was introduced to Japan in the Song Dynasty from China and integrated with the Japanese social culture, so as to create a new cultural phenomenon that kept the original characteristics and harmonized the Japanese social features, which grew into a kind of custom and social norm rooted in Japanese society. Righteousness and human relationships are not contradictory but integrative and cannot be separated.
