The Cast-Iron Pan That Never Needs Replacing: Japan's Nambu Tekki vs Your Nonstick Drawer

The nonstick pan you cook on has an expiration date its own maker set: 3 to 5 years, then you buy another one. A bare Japanese cast iron pan ends that loop for life. This video runs the honest math on Nambu tekki, the centuries-old cast iron of Iwate, Japan, against the nonstick pan you keep rebuying. It covers where the pan comes from (Iwate's 900-year iron-casting tradition and the Oigen foundry, casting since 1852), what seasoning actually is (real oil polymerization, a hard bonded surface, not folklore), the one small step that makes most people quit cast iron, why the old never-use-soap rule stopped being true back in the 1950s, and the honest limits: the weight, the slow heat-up, hand-drying so it never rusts, and the acidic foods to keep off a young pan. One pan, bought once for about $109, that gets better with age instead of wearing out.
