Origin and Style: This is Kutani-yaki (Kutani ware), a traditional craft of Ishikawa Prefecture, featuring vibrant overglaze painting using the "Kutani Gosai" (five colors of Kutani: cobalt blue, red, purple, green, and yellow). Design: The tokkuri (sake bottle) is decorated with bird and plant motifs, while the multiple sakazuki (sake cups/ochoko) feature different designs such as birds, pomegranates, and geometric patterns. Artist: The painting on the tokkuri and sakazuki is said to have been created or supervised by Isokichi Asakura (recipient of the Order of Culture), a master of Kutani-yaki, and/or his sons (Yoshinari and Masahiro).
