As the named "Stuffed Yu Sausage" suggests, these are yukkuris which are used to contain the sausage stuffing. Preparations begin in my area half a month before the new year.
Healthy koyukkuris are selected, and at two weeks of age they are stuffed into special bamboo tubes or wooden containers. This is so they will grow into elongated shapes. During this period the yukkuris cannot be removed from the vessels. All that's needed is to feed them daily.The Spring Festival is here! Everyone prepares food for the celebration. The tradition in my area is to prepare large amounts of dried meatstuffs. The most impressive among these is the "Stuffed Yu Sausage."
