🍱 Kaiso Yose (Seaweed Yose)

"Kaiso Yose(=Seaweed yose)" is a local dish eaten along the Kashima coast, extending from Kashima in Ibaraki Prefecture to Choshi in Chiba Prefecture. One of these is kotojitsunomata and tsunomata, which are the main ingredients of "Kaiso Yose(=Seaweed yose)". The Katsuraura coast is blessed with various marine delicacies because it is a convergence point where the Kuroshio Current and Oyashio Current collide. Choshi Port boasts the highest volume of catches in Japan, and in addition to fish, you can also catch an abundance of seaweed. "Kotojitsunomata" is a 20-cm-tall seaweed that attaches to rocks in the intertidal zone. It is said to be named after the shape of its branches, which resemble the pegs that support the strings of a koto, a traditional Japanese musical instrument. Taking advantage of its property to thicken when heated and solidify when cooled, it was historically used as soap and adhesive. At the end of the year, merchants from Choshi came to sell "kotojitsunomata" for New Year's, and "seaweed yose" came to be made into Osechi dishes.
