The “Komaru” Cast Iron Kettle by master craftsman Rikuchō Ogasawara (1929–2012) is a timeless reimagining of the traditional Japanese tetsubin for modern everyday life. Handcrafted in Iwate, Japan, using the historic Nambu Tekki cast iron tradition with over 400 years of history, this kettle embodies durability, heat retention, and the quiet beauty of Japanese ironware. ・Charming Round Design True to its name, Komaru (“little round”), the kettle features a perfectly rounded body that feels comfortable in the hand. Its textured cast iron surface and balanced weight reflect the essence of authentic craftsmanship. Unlike many traditional tetsubin that can feel distant or ceremonial, Ogasawara named this a “kettle” to emphasize its role as a familiar, approachable daily tool. ・Functionality with Tradition The Nambu cast iron kettle not only boils water but also naturally improves its flavor. Cast iron reduces chlorine odor and allows for subtle iron intake through daily use, making it both functional and beneficial to health. Compact, affordable, and designed for accessibility, the Komaru kettle makes the tradition of Japanese cast iron available to everyday households around the world. ・Long-Lasting and Sustainable With proper care, cast iron can last for generations, developing a unique seasoned patina that enhances both its appearance and usability. Though maintaining a cast iron kettle requires more attention than an electric pot, this daily care fosters a deeper connection between user and object. Over time, what begins as a routine becomes a meaningful ritual. ・A Lifelong Companion More than just a tool for boiling water, the Komaru Cast Iron Kettle offers a slower, more intentional way of living. Each piece is handmade by skilled artisans, ensuring slight variations that add warmth and individuality. Practical, sustainable, and rooted in tradition, this kettle is not only a piece of functional cookware but also a lifelong companion crafted to enrich everyday moments. ■Product Information Brand: Ogasawara Rikuchō / Nambu Tekki, JAPAN Product: Cast Iron Kettle (Tetsubin) Size (Overall): W18.0 × D15.5 × H21.0 cm (W7.1 × D6.1 × H8.3 in) Body: Ø15.5 × H10.5 cm (Ø6.1 × H4.1 in, without handle & lid) Bottom Diameter: Ø10.7 cm (Ø4.2 in) Capacity: approx. 1.0 L full / ~0.7 L recommended (34 oz / ~24 oz) Weight: approx. 1850 g (4.1 lbs) Material: Cast Iron (traditional Nambu Tekki, durable and long-lasting) Heat Sources: Direct Fire / IH / Charcoal Not Suitable For: Microwave / Dishwasher
