There are two types of tokkuri (sake bottles). The single one is a Ryusho piece from Kutani ware. It is a work by Hiroyuki Kida. Mr. Kida uses traditional Kutani techniques to create powerful yet delicate expressions. The set of two tokkuri and five ochoko (sake cups) is from Shozan of Kutani ware. The Shozan kiln is one of the Kutani ware kilns. Its characteristic feature is the overglaze painting, which is a characteristic of Kutani ware as a whole, and the beauty of the colored decorations is particularly outstanding.
