おかげで・おかげだThanks to; owing to a helpful cause

Credits a person, thing, or circumstance for a welcome result. It often expresses gratitude or appreciation, not merely a neutral cause.

Giving credit for a good result

おかげで links a helpful cause to the result that follows. The person who benefits does not have to be the speaker, but the result should normally be clearly welcome to someone.

People and helpful circumstances

The credited cause may be a person's help or simply a favorable condition.

Choosing the right cause expression

おかげ gives positive credit. せい instead assigns blame for an unwelcome result. Use ので when you simply want to give a reason without built-in praise or blame; ため is common for a more report-like statement of cause.
