关于本原料
Premium kombu variety from the Shiretoko-Rausu coast in eastern Hokkaido. Distinguished by an exceptionally rich, slightly fattier dashi character — sometimes called the 'king of kombu' in Kansai dashi circles. The cold Sea of Okhotsk waters around Rausu and the steep underwater shelf produce slow-growing kombu with thick, deeply flavoured fronds. Allocation-controlled supply through the Rausu Fisheries Cooperative; commands the highest per-kg pricing of any Japanese kombu variety. Distinct from the existing rishiri-kombu and ma-kombu entries in profile and price.
