としてAs (i.e. in the role of), For

When the case marking particle と is used to highlight a result, it regularly translates to 'as' in English. This nuance of 'as' simply assumes that (A) is a plain or unchanging fact from which something (usually an opinion or evaluation) is based. Combining this nuance of と with して (the conjugation form of する), として will present (A) as the base point from which (B) can be determined.

Despite being a combination of several individual parts, として is often considered to be a 副助詞(ふくじょし) (adverbial particle) by itself, meaning that it will most often be seen connected directly to nouns.

• ミキは友達(ともだち)としては最高(さいこう)だ。

  As a friend, Miki is awesome.
• このゲーム機(き)はDVDプレイヤーとしても使(つか)えます。

  You can use this game console as a DVD player.

As として works in the same way as a 副助詞(ふくじょし), it may be connected directly to a second noun to express that (B) is something functioning as (A).

• 動物(どうぶつ)を傷(きず)つける奴(やつ)は人間(にんげん)として失格(しっかく)だ。

  People who hurt animals are a failure as humans.
• これは会社(かいしゃ)としての目標(もくひょう)です。

  This is the goal as a company.

Fun Fact

This result use of と regularly appears when one particular aspect of something is being highlighted (while other aspects still exist). This simply means that nothing apart from (A) is being considered when expressing (B).

• タナカさんは友達(ともだち)としてはいい人(ひと)なんだけど、先輩(せんぱい)としてはよくない。

  Tanaka-san is a nice person as a friend, but not as a senpai.
