This black Raku tea bowl by Raku Tokunyū VIII reflects the classic techniques of the Raku lineage, formed by hand without the use of a wheel (tezukune) and shaped through direct touch using fingers and simple tools. The bowl’s softly rounded body and subtly irregular lip enhance its wabi-sabi character, emphasizing intimacy, tactility, and use. Fired at low temperature in a small kiln, the deep, lustrous black glaze (likely inherited from his father Chōnyū’s glaze formula) was achieved through reduction firing, resulting in a rich, glossy surface.

The bowl is titled Konoshitayami (木の下闇), meaning “darkness beneath the trees,” a poetic phrase frequently used in waka poetry and tea culture to evoke filtered light, quiet shelter, and contemplative shadow. This imagery resonates with the bowl’s enveloping form and subdued black surface, suggesting a protected, inward space central to wabi-cha aesthetics.

Rather than being signed, the bowl bears only the impressed Raku family seal, stamped here on the side of the body rather than on the foot. Tokunyū did not personally inscribe his works, and no signature bearing the name “Tokunyū” exists, as the name was granted posthumously after his death. Authorship is thus expressed through lineage, technique, and seal, revealing a youthful yet faithful adherence to Raku tradition.
