How to say "besides" in Japanese

Choosing the right word
  • しCommon
    particle, conjunctionCovers the additive 'and besides, what's more' sense: it adds one more reason or point to what has just been said. Typical when you are listing reasons for a judgment or choice.
    トムも来こなかったしジェーンも来こなかった。↗
    Tom didn't come, nor did Jane.
  • かつJLPT N1approx.Common
    conjunction, adverbCovers the additive 'and, moreover, as well as' sense: it joins two parallel points or qualities, asserting both at once. Usually written in kana; typical in written statements that affirm two things together.
    彼かれは作家さっかでもあり、かつまた政治家せいじかでもある。↗
    He is a writer and a statesman.
  • adverbAdditive, with the 'on top of that' feel of its gloss: adds a further point beyond what was already stated. Typical when you want to stress that something applies even more than first said.
    彼女かのじょは快活かいかつで愛想あいそがよく、親切しんせつでなおかつ思おもいやりがある。要ようするに立派りっぱな人ひとです。↗
    She is bright, friendly, kind, and considerate. In brief, she is a good person.
  • かたわらJLPT N1approx.Common
    no-adjective, adverbReally means 'side; edge; beside' — a word of physical location. Its 'besides' reading is marginal: doing one thing alongside another, 'on the side'. Seldom the word you want for the additive 'besides'.
    メアリーは読書どくしょをしており、1匹ひきの猫ねこがかたわらで眠ねむっていた。↗
    Mary was reading, with a cat sleeping beside her.
  • 以外いがいJLPT N4approx.Common
    noun (suffix)This is the 'besides' that means 'other than, apart from': it marks what is excluded from the statement. Use it where 'besides' could be replaced by 'except', not for adding a further point.
    その仕事しごと以外いがいならなんでもやる。↗
    I'll do anything but that job.

For the additive 'what's more' sense of 'besides' choose 「し」, 「かつ」 or 「なおかつ」; for the 'other than, apart from' sense use 以外; 「かたわら」 is really 'beside' and only marginally 'besides'.
