The Kamado grill has its roots in ancient cooking methods, tracing back thousands of years. The word "kamado" is a Japanese term that translates to "stove" or "cooking range." The design and concept of the Kamado grill have evolved over time and have been influenced by various cultures.

Chinese Qin Dynasty (221–206 BC):
The origins can be traced back to the Chinese clay cooking vessels called "tandoors," which were used to bake bread and roast meats.

Japanese Mushikamado:
The design was adapted by the Japanese into a mushikamado, a clay pot with a removable domed lid and a base. This design was used for steaming rice and later evolved for grilling and smoking.

Post-WWII Adaptations:
After World War II, American servicemen stationed in Japan brought these clay cookers back to the United States. The design was further modified and commercialized in the Western market, giving rise to the modern Kamado grill.
