This is soba which is Japanese buckwheat noodles.
In Japan people eat soba at New Year’s Eve.
It is called Toshikoshi soba.
It is a Japanese custom which started in the Edo era.
Soba is easier to cut than other noodles.
So people eat it as meaning to cut out the calamities of the past year.
They eat it with shrimp tempura, fried bean curd, etc.
I like to eat it with Nishin (cooked herring ).
This is the Kyoto style for eating soba.
