🍚 Bakudan onigiri
The Oki Islands are an archipelago in the northeast of Shimane Prefecture, consisting of four main islands and more than 180 smaller islands. The area is 346.22 km2, and the coastline extends 468 km. Surrounded by the sea, the Oki Islands produce a wide variety of seaweed. In winter, seaweeds such as laver and arame are harvested, and in spring, tengusa and hijiki are harvested. From December to February, when the northerly winds blow, the rock seaweed fishing begins. Aiming for calm days when the sea surface is still, the fishermen gather on the rocks at the water's edge and carefully gather the seaweed that has grown on the rocks. This "nori picking" has become a winter tradition in Oki. The rock seaweed harvested in Oki has a reputation for being thick, crunchy, and fragrant. After harvesting, the seaweed is pre-treated to remove pebbles and other debris, and then processed into laver sheets. Most of the seaweed is consumed locally, but some is distributed in and out of the prefecture. It is also an indispensable ingredient in the "iwanori zoni" (a traditional Oki delicacy), and is an essential ingredient for the New Year's holiday. Bakudan-onigiri" is a popular lunch box or snack that makes lavish use of iwanori. The name "bakudan" is derived from the appearance of the large, round rice ball covered with iwanori seaweed.
