About this ingredient
Pickled daikon radish — a foundational Japanese tsukemono with 400+ year heritage. Production methods: shio-takuan (salt-only), nuka-takuan (rice-bran fermented, the heritage style), kasu-takuan (sake-lees pickled). Iyo (Ehime) and Hyogo dominate commercial production. Modern industrial-scale takuan often uses turmeric for the iconic yellow color; heritage producers preserve the traditional white-aged version. Distinct from existing fermented food entries.
