A traditional brush used in everyday Japanese kitchens.

This small, quiet tool
has long been used in Japanese kitchens.

Made from natural plant fibers,
it’s especially suited for cleaning cast iron.

Nothing fancy.
Just something that works.

What is a Karukaya brush?

A karukaya brush is made from the roots of a grass plant
and shaped into a slim, stick-like scrubber.

Because the fibers don’t absorb oil,
it removes residue without stripping the seasoning too aggressively.

It also dries quickly after use,
making it clean and easy to handle.

Made for everyday use

As the brush wears down,
the binding can be removed
so it can be used for longer.

Two sizes are available,
both comfortable to hold
even for smaller hands.

The fibers are firm,
so gentle pressure is enough.

Often paired with cast iron pans
such as River Light.

If you care for cast iron regularly,
a simple brush like this makes a difference.

This is the one I use in my own kitchen.
