A Natural ash glazed matcha tea bowl by Doi Masafumi, an artist trained in the fine tea tradition of Kyoto who creates works that balance everyday usability with a striking sense of design. The final color of each piece remains unknown until the firing is complete, and among his many bowls, this one stands out for the exceptionally beautiful blue that emerged from the kiln. The bowl measures 12.5 x 8.8 cm (5 × 3 1/2 inches) and comes housed in an original wooden box signed by the artist, titled Yohen Chawan (Kiln‑altered Tea Bowl). It was obtained directly from the artist at the end of 2025 and is in new condition.
Doi Masafumi was born in Nara prefecture in 1972, and graduated the Aichi prefectural ceramic research facility in 2000. For the next seven years he would work at a kiln in Kyoto, absorbing the many styles and techniques associated with Kyo-yaki before establishing his won kiln back in Nara. He held is first solo exhibition in Kyoto in 2009, and in 2011 was awarded at the Nihon Togeiten National Ceramics Exhibition, where he has been featured many times.
