AI-assisted summary
Description from the seller
Item Description
This work is a yakishime (unglazed, high-temperature fired) spherical flower vase by ceramic artist Kobayashi Masami (born 1952), who is based in Kasama City, Ibaraki Prefecture. He is known as one of the leading artists representing Kasama ware (Kasama-yaki).
The vessel form is rounded like a ball, with a small opening positioned slightly off-center at the mouth. The surface transitions in a gradation from a deep moss green at the shoulder to a pale sandy tone toward the base, displaying the distinctive texture of yakishime firing produced by wood-kiln firing and the action of ash. Across the entire vessel, fine root-like incised lines (sgraffito decoration) spread organically downward from the neck, which is the origin of the work's title, "Yakishime Senmon-ki" (Yakishime Incised Line Vessel). A small impressed seal design can also be identified near the base on one side. The unglazed foot ring reveals an iron-rich clay body characteristic of reduction firing, with a glossy reddish-brown glaze accumulation at its center.
This work comes with its original wooden box (tomobako, approx. 13.5 × 13.5 × 13 cm), making it a collector's item with documented provenance.

Artist Profile
Kobayashi Masami was born in 1952 in Hokkaido, Japan. He originally aspired to become an industrial designer but encountered ceramics along the way, and in 1972 began studying under master ceramicist Nakano Koji. He was part of the wave of artists who relocated to Kasama, Ibaraki Prefecture, helping to establish it as a prominent centre for contemporary Japanese pottery, where he remains based today.
His accolades include the Excellence Prize at the Ibaraki Prefectural Arts Festival Exhibition (1974, 1975, 1978), the Gold Prize at the International Ceramics Exhibition (1982), the Mainichi Grand Prize at the Kasama-Mashiko Ceramics Artists Exhibition (1994), and the Grand Prize at the North Kanto Ceramics Exhibition (1998-1999).
His work has been shown at the Suntory Museum Grand Prize Exhibition (1991), the 12th Japan Ceramics Exhibition (1993), and the 35th Japan Contemporary Crafts Exhibition, where he received the Contemporary Crafts Grand Prize (1996). He later held a solo exhibition at Matsuya Ginza Gallery in Tokyo (2011).
Kobayashi's works have also been acquired by museums abroad and featured in exhibitions overseas, reflecting international recognition of his practice. His work is characterised by abstract, free-form sculptural ceramics, held in both private collections and public museum holdings.

Seller's Story
We have been experienced as an antique dealer for more than a decade, we select and purchase high-quality products from all over Japan. I carefully select items with good taste, whether famous or not. I offer you an encounter with unknown Japanese goods.
Owner Profile
Name: Michito Nagahiro
Born in 1986 in Sapporo, Hokkaido. From an early age, I have been fascinated by the beautiful and practical designs of Japanese art, antiques, and consumer products, as well as the mindset and dedication of craftsmen and artists. I frequently visited museums and solo exhibitions as part of my daily life.
In 2012, under the guidance of a top mentor in the industry, I established myself as an antique dealer, handling a wide range of items, including Japanese antiques and artworks. Since 2017, I have specialized in selling Japanese antiques and fine art, primarily in Europe, achieving over 20,000 successful sales to date.
In 2019, I launched a completely free service to support individuals in Japan who experience loneliness. This initiative involves personally visiting people, engaging in conversations, sharing meals, and, if necessary, providing career advice. More than 1,000 people reach out to me annually for support.
Additionally, I am committed to promoting and supporting the sales of emerging artists whose work has not yet received public recognition. My philosophy goes beyond merely selling objects—I strive to convey the stories, history, and emotions embedded in each piece. By doing so, I aim to connect people with the lives of the artists and bring inspiration to those who encounter their work.
