Plenty of traditions here. And I mean plenty.
New Year's Eve calls for soba noodles, which symbolizes long life, then, there's a big TV song fest that pairs male and female singers for song matches, then the total is tallied for a team win. After that, there's the two year worship, going to a neighborhood shrine or temple and worshiping for the first time in the New Year. While waiting in line, the Buddhist temple bells will ring 108 times to cast out the 108 worldly temptations that plague us humans.
Come the morning, first, we toast with "toso" sweetend sake(Japanese alcohol) spiced with an herb

okay, this is a very expensive laquered set, ours is more like the following

,
then we eat special New Year food (this is for the entire family for Jan 1 through Jan 3, not one serving for one person)

that includes a special soup that differs with regions, it's either miso based or clear soup

, but always with "mochi" rice cake in it. Then, people troup off to the local shrine or temple if they hadn't gone on New Year's Eve. Families gather at their parents' homes, and children get special New Year allowances. Traditional play like kites and tops and a game thats somewhat like badminton, only with wood paddles, card games, board games, etc etc.
Or, a quiet 3 days (New Year holiday is Jan 1-3 here, with most people off from Dec 28-31 as well for the end of year holidays) if one prefers.
I'll probably be joining friends at a Jazz club after I finish household chores on New Year's Eve, will go to my mother's on Jan 1 as my brother will be coming also, on Jan 2 go to a shrine that I often accompanied my father on New Year, then on the 3rd, I intend to visit my father's grave since it's his birthday.
Then it's back to work on Jan 4.
