Japanese "Itadakimas" is not Let's eat.
I thihk living in some country provide special experience for us because we can use language in cultual back ground. For example, Japanese people say "Itadakimasu" before eating. This means not equal "Let's eat". When we eat meat or fish, we deprive "life" from cow, pig, chicken, sarmon, yellowtail and any other creatures. Itadakimasu has meaning of appreciate for the life .
I found another aspects to understand the culture "itadakimasu". I beleave that there are "Yaoyorozu no Kami" around us. Yaoyorozu no Kami is one of the god live in eventhough a grain of rice. We are gratly appreciated to ear something. So "Itadakimasu" is not just sign for start eating but thank you for everything to regadring someones life.
I feel that language including someone's sowl. But we can not aquire the language like Rome was not built in a day. So I want to live in abroad and I would like to found culture in the country.
