Morioka cold noodles were first made by a native of Pyongyang on the Korean Peninsula, who improved on the authentic taste. Morioka cold noodle is characterized by its firm translucent noodles made of wheat flour and potato starch, and many people are attracted by the unique flavor of the noodles with a firm texture, the rich soup made from beef bones, and the spiciness and sourness of kimchi. Those who do not like spicy food can adjust the spiciness by the amount of kimchi. At the "Pyonpyonsha Cold Noodle Factory" in Morioka Handmade Village, visitors can experience making cold noodles by hand.

Cold noodles are one of the three most popular noodles in Morioka (wankosoba, cold noodles, and jaja-men).
