All Ichiseibutsu (lifelong item) iron products are delivered with an official certificate of authenticity from Japan.

Iwate Prefecture, located in northern Japan, is renowned for its traditional craft, Nambu Tekki—a distinguished form of ironware celebrated for its craftsmanship and heritage.

Renowned for its exceptional durability, Nambu Tekki is often said to last for generations—strong enough to be passed down to one’s grandchildren. However, due to its popularity, counterfeit products have become widespread, making it difficult to distinguish authentic pieces when shopping online.

At Phenimax, we offer only genuine Nambu Tekki, handcrafted one by one in the kiln of master traditional craftsman Mr. Sasaki, the third-generation head of Kaoruyama.

A genuine Nambu Tekki iron kettle helps stabilize the water quality, adapting to different water compositions across various countries. This enhances not only Japanese tea but also coffee and cooking, elevating flavors to new heights.

At Phenimax, we exclusively offer handcrafted, lightweight, and finely crafted Nambu Tekki, personally guaranteed by Mr. Sasaki. Each piece comes with an official certificate of authenticity and is delivered directly from Japan.
