Although I will do a couple of more detailed posts, here is the small feast we laid out for New Years Osechi Ryori.
Here, you can see that there were a few meats, Chinese BBQ Pork (cha siew), some Maguro and Hamachi sashimi, Futomaki and Braised pork belly stew. That small dish in the middle is true fresh ground wasabi, nothing you have had, from tube or powder gets close.
In this picture, you can see that Futomaki (sushi rolls), along with Kitsune sushi (inarisushit), Sugar cured cucumber (Tsunemono), Oden (a fish stew), Teriyaki Chicken and some fresh crabs, and again, the braised Pork belly stew.
There were other dishes, such as kuromame, a traidtional food for good health, various salted and mirin-cured vegetables, most of which have some association with good luck or good health. Pork belly is a rarity, but, would have been most common as a winter food, as it would have been most common for slaughter to happen in late fall. The oden is another traidtional dish, and really represents Spring and rebirth, with the use of spring vegetables, such as bamboo shoots, fuki (coltsfoot) and renkon.
