The Nakamura family in Tokyo produces square, copper frying pans that are made especially for cooking excellent Japanese rolled omelets. The father is the boss, and under him, his 3 sons work, manually making the superb frying pans one by one. 2 of the sons are already married, and as such, they bring bento to work on most days, but on some special days, the mother of the family cooks lunch for everyone, and that's when they sit together and eat like the family they are.
