GOCHISOUSAMA
After finishing a meal in Japan, it is polite to say gochisousama (Goh-chee-sou-sama). This is an expression after the meal to express gratitude to the meal (and to someone who may be treating you). The translation can roughly be seen as “Thank you for the meal”. Now don’t get gochisousama mixed with arigatou! While both may have thank you in them, arigatou should be used when thanking someone, while gochisousama is strictly used after a meal.
