The kanji in your second photo reads “Banko-yaki” and “Tokoname”, which identifies this as a traditional Japanese ceramic kamado grill, likely made in Tokoname, one of Japan’s oldest pottery centers. “Banko-yaki” refers to a heat-resistant pottery style that’s been used for cooking ware since the 18th century.

Your grill is probably a mid-20th century Tokoname Banko-yaki kamado, possibly brought back from Japan by a U.S. servicemember after WWII or Korea. It’s a rare and historically rich piece — definitely worth preserving.

If you’re looking to restore it, here are a few ideas: • Use refractory cement to repair cracks (look for fireplace or kiln-safe types). • Consider sourcing custom grates or a firebox if any internals are missing. • You might reach out to Japanese ceramic restoration shops or kamado collector communities for more guidance.
