At the Tsubame Industrial Materials Museum, you’ll experience the artistry behind tsuiki-doki—a traditional metalworking technique where a single sheet of copper is hammered into shape. Guided by this centuries-old craft, you will add your own hammered patterns to create a one-of-a-kind pure copper tumbler. It’s not only a hands-on introduction to Japanese craftsmanship, but also the chance to take home a unique work of art made by you.
