noun
warm friendship; cordial relations
A somewhat formal or literary term for a close, friendly relationship. Often used in written contexts or formal speech.

友情 is the common word for 'friendship' and is used in everyday conversation. 好誼 is more formal and often implies a relationship between groups or in official contexts.
親交 also means 'close friendship' but is slightly more common and less formal than 好誼. 好誼 carries a nuance of goodwill and warmth.
Compound of 好 (good, friendly) and 誼 (friendship, goodwill). The exact historical derivation is uncertain, but the word is used in modern formal Japanese.
