The source of the name “SHUCHU YORU OKU Ⅰ” refers to the phase from a classic Chinese poem. The piece is made by using a hand-forming technique, which is the traditional style of Raku ware. This is a thin, shoe-shaped tea bowl. The undulating peristome is quite gentle with the rim partially being pushed inward. The whole body is unevenly covered with an ocher engobe. The area from the mouth to the notched hip is covered with an ash glaze. From the rim to the body, there are a myriad of lines of a black, a green glaze. It looks as if shallow water plants and a boatman in a breeze under a full moon. Inside the trimmed foot of the piece, the ‘RAKU’ mark of Kichizaemon XV is impressed. This work is one of the “Night Voyage” series.
