In Japan, we admired nature which brought the blessing of the meal with God and came since ancient times, and we have the mind to respect.
We made various annual functions and festivals, traditions; means of the thanks of prayer and the crop of the good harvest and big catch. We gave "Shinsen" as a votive offering to God. "Shinsen" was a meal of God, and we were thinking that we were protected by God to eat a thing same as the meal.
The mind and tradition are inherited at the present, and make the origin of the Japanese meal-style.
