Kumagai

Kumagai Kajiya, also known as Kumagaya Blacksmith, is a tenth-generation workshop in Ofunato, Iwate, crafting professional fishing gear, durable gardening tools, and traditional ironware. Each tool is hand-forged with time-tested blacksmithing techniques, trusted by fishermen, divers, coastal harvesters, and gardeners for strength, sharpness, and long-lasting performance.

The lineup includes premium oyster knives, abalone hooks, scallop nata, tools for sea urchin, octopus, wakame, and onboard work, as well as precision weeding sickles, groove cutters, and grass-cutting blades.

This category also features the Sanriku Iron Abalone, a Nambu cast-iron item shaped like the local Sanriku abalone shell. When boiled in water, it naturally releases iron, making daily iron supplementation easy and helping improve circulation, energy, and hair quality. It also enhances soups, stews, and teas by removing chlorine and boosting flavor.
