For past actions, you can say ありがとうございました (Arigatou gozaimashita) , which thanks someone for something done in the past. Other variations include:
- どうも (Doumo) — a casual "Thanks!"
- どうもありがとう (Doumo arigatou) — a more polite "Thank you very much"
- どうもありがとうございます (Doumo arigatou gozaimasu) — very polite "Thank you very much"
- 本当にありがとうございます (Hontoni arigatou gozaimasu) — "Really, thank you very much," adding extra emphasis.
