とろろ昆布 (とろろ昆布)

Toyama's vinegar-aged tororo-kombu craft produces shaved-kombu that no other origin replicates; 200+ year heritage.
Glutamate elevated by aging; iodine 100-300 mg/100g; thin-shave melts instantly in hot water.
Instant-dashi soup, onigiri filling export, hospitality umami garnish.
Vinegar-aged, paper-thin shaved kombu — a Toyama / Fukui specialty. Made by stacking aged whole kombu, pressing through vinegar fermentation, then shaving with razor-thin precision. The shaved-kombu format dissolves rapidly in hot water (a quick instant dashi) and adds umami to onigiri / soup / udon. Toyama produces ~80% of Japan's tororo kombu; Yamatoya and Kobashi-Showado are reference producers. Distinct from existing kombu entries (raw kelp varieties).
