One vessel has two clear roles
Iwachu presents model 12804 as an iron kettle-and-teapot combination rather than an enamel-lined serving pot that must stay away from direct heat.
Iwachu · Model 12804 · Made in Japan
A Japanese-made 0.65-liter cast-iron vessel with an unenameled interior, black baked finish, tortoise-shell pattern and removable tea strainer, listed for use as both a direct-fire kettle and a teapot.
What it changes in the tea ritual
Model 12804 is compelling because its purpose is not limited to serving. The unenameled iron body is listed for direct-fire water heating, while the included strainer lets the same compact vessel move into a teapot role once the flame is off.
Iwachu presents model 12804 as an iron kettle-and-teapot combination rather than an enamel-lined serving pot that must stay away from direct heat.
The current listing specifies no interior enamel, which supports the kettle role but also requires drying and maintenance unlike an enamel-lined teapot.
A removable tea strainer is listed with the vessel, allowing the same body to move from heating water to brewing and pouring.
The listing identifies Iwachu, Nambu ironware and Japanese manufacture instead of relying only on a general Japanese-style description.
The black baked finish and geometric new-tortoise-shell motif bring visible iron character to a vessel with a listed full capacity of 650 milliliters.
Who it is for
It suits someone deliberately choosing authentic Japanese Nambu ironware, direct-flame compatibility and a compact serving volume over lightweight, maintenance-free convenience.
