How to say "As a <position>, ..."


Example : **As a friend** , I think we should...

What do you add to ともだち to add the "As a" prefix?

Also, after that part, does the rest of the sentence follow the normal rules
of a Japanese sentence?

What I mean is, could I comfortably add "As a friend" at the start of any
Japanese sentence without changing anything for it to make sense?

Edit : Also, if you could put your answers in both Kanji and kana, that would
be great, since I do not understand Kanji yet. Thanks




Generally speaking, ～として is used for "as a". You use a noun before として. For
example:

> As a friend...  
>  友{とも}だちとして...
