In Japanese culture, the phrase "Itadakimasu" is said before what?

As Japan has a healthy background of Buddhist culture, it’s not surprising that itadakimasu is also related to the Buddhist principle of respecting all living things. Before meals, itadakimasu is said as a thanks to the plants and animals that gave their lives for the meal you’re about to consume. It also thanks all those involved, ranging from the hunter/farmer to the preparer of the meal. It’s common to say itadakimasu before eating a meal. The word itadakimasu is often translated as “I humbly receive,” but when relating to food, it’s often compared to saying “Let’s eat,” “Bon appétit,” or “Thanks for the food.” Some even compare it to the Christian tradition of saying grace before a meal.
