Wooow! This 'Osechi' is so beauuutiful! Osechi is a traditional New Year's feast in Japan. Its ingredients are metaphors/wishes for different things. Since it is so elaborate and filled with some delicacies, it's nearly always the most complex and expensive meal a Japanese family will eat, if they can afford to eat one.

I heard each and every dish has their own special meaning~

Ro-chan has memorized them all~.

"Kuromame" have the meaning of "working diligently". Black soy beans. "Mame" is bean, but "mame" can also mean diligent.

"Kazunoko" means "prayer for many children." Herring roe. Literally, "children of herring". "Kazu" also means "counting (many)", so it symbolizes having to count up many children.

"Tatsukuri" means "to be fertile," I think? Sardines in soy sauce, the name also means "make rice paddies," because sardines were historically used as fertilizer for rice. It actually symbolizes, "wishing for a fertile (rice) harvest," although Ro is confusing it for children, here.

"Datemaki" is also... "children," probably. A rolled fish-paste and/or shrimp omelette. It references "being fashionable" because fashionable clothes are worn on auspicious occasions. Hence, it actually means, "wishing for auspicious days."

That one's "children," too!
