because, since (objective reason)

ので gives a reason in a softer, more objective way than から, so it suits polite requests and explanations. It follows plain forms, with な after na-adjectives and nouns: 静かなので, 学生なので. In very polite speech it can follow ます forms.

Examples

• 頭あたまが痛い[いたい]ので、早はやく帰かえります。

  Atama ga itai node, hayaku kaerimasu.

  Since I have a headache, I will go home early.

• 明日あすは試験しけんがあるので、今晩こんばん勉強べんきょうします。

  Ashita wa shiken ga aru node, konban benkyou shimasu.
