Description:

Xandre Store Exclusive - A Distinctive Work of Contemporary Okinawan Glassmaking

Artist: Seikichi Inamine (稲嶺 盛吉)

Studio Tradition: Chu-Fuki Glass Studio “Niji” (宙吹ガラス工房「虹」)

Origin: Yomitan Village, Okinawa, Japan

Category: Okinawan Hand-Blown Glass | Fine Art Rock Cup | Studio Tableware

Craft Tradition: 宙吹ガラス (Chūfuki Glass)

This exceptional Ryukyu hand-blown rock cup by Seikichi Inamine (稲嶺 盛吉) presents a compelling fusion of Okinawa's elemental landscape—earth, stone, and Pacific Ocean—through the language of contemporary studio glass. Recognized as a Contemporary Master Craftsman (現代の名工), Inamine is one of the most influential figures in the development of modern Okinawan glass art. His approach transformed the expressive possibilities of Ryukyu glass, moving beyond purely utilitarian forms toward highly individual works distinguished by texture, color, movement, and naturalistic inspiration.

This particular vessel is especially striking for its contrast between earth-toned crackle textures and a powerful cobalt-blue oceanic swirl. The lower body transitions through warm terracotta and sandy mineral tones into a pale, stone-like crackled surface. Around this foundation flows a substantial ribbon of deep cobalt blue and turquoise glass, creating the impression of Pacific water moving around weathered Okinawan rock. The juxtaposition is dramatic: rough against smooth, earth against ocean, opacity against translucency. The base carries an impressed 「吉」 (Yoshi) mark, providing an important physical identifying feature associated with Inamine's studio tradition.

Seikichi Inamine - A Defining Figure of Modern Ryukyu Glass

Seikichi Inamine (稲嶺 盛吉) occupies an important place in the history of contemporary Okinawan glassmaking. Working within the distinctive tradition of Okinawan recycled-glass production, Inamine became known for pushing the material toward increasingly expressive and sculptural forms. His artistic vocabulary embraced organic textures and unconventional materials, including natural substances incorporated into hot glass to produce surfaces evocative of earth, stone, ash, sand, and other elements of Okinawa's landscape.

As founder of Glass Studio “Niji” (宙吹ガラス工房「虹」) in Yomitan Village, his work helped establish an influential studio tradition that continues through subsequent generations of Okinawan glass artists. The Japanese designation 現代の名工 (Gendai no Meikō / Contemporary Master Craftsman) further reflects the high level of craftsmanship associated with his career.

Earth, Stone & Pacific Water

The artistic character of this cup is particularly compelling because its surface seems to translate Okinawa's natural environment directly into glass.

Earth: Terracotta and sandy mineral tones form the foundation, recalling the warm soil and weathered landscapes of the Ryukyu Islands.

Stone: The crackled exterior introduces a rugged, geological quality. Its irregular surface gives the vessel an almost ceramic or volcanic appearance despite being formed from glass.

Ocean: A sweeping band of cobalt and turquoise glass encircles the body, bringing the unmistakable visual language of the surrounding Pacific into the composition.

Together, these elements create a small-scale landscape in the hand-a distinctly Okinawan interpretation of contemporary studio glass.

The Signature Crackle Surface

One of the most visually compelling aspects of the vessel is its organic crackle-like surface treatment. Rather than presenting a perfectly smooth commercial finish, the exterior possesses an irregular mineral character that gives the cup considerable tactile depth. The surface catches light differently across its uneven contours, allowing the warm earth tones and pale mineral colors to shift subtly as the vessel is viewed from different angles. This tactile quality is central to the appeal of Inamine's work: the glass is experienced not only visually, but also through the hand.

Ocean Cobalt Sculptural Swirl

Encircling the body is a substantial sculptural ribbon of cobalt blue and turquoise glass. Its glossy character contrasts sharply with the earth-toned crackle beneath it, creating a sense of movement and depth. The blue element also serves a functional purpose, providing a natural gripping area while becoming one of the vessel's dominant artistic features. The result is a rock cup that feels simultaneously organic, sculptural, and functional.

Authentic Studio Marking

A particularly important feature for collectors is the impressed marking on the base:

「吉」 - Yoshi The mark is physically impressed into the bottom of the vessel and forms part of the object's identifying characteristics. For a collectible studio-glass work, such a maker or studio mark can be particularly valuable because it provides a tangible connection between the individual object and the artist's workshop tradition. Xandre Store recommends preserving detailed photographs of the mark as part of the item's permanent collector documentation.

Collector Significance

This cup offers a remarkable combination of artistic heritage, tactile craftsmanship, identifiable studio marking, and distinctly Okinawan visual language.

Rather than attempting to imitate European glassmaking traditions, Inamine's work demonstrates how Okinawan glass developed its own contemporary artistic vocabulary—one deeply connected to the island's environment and cultural landscape.

The piece is therefore suitable not only as functional tableware but also as a collectible example of modern Ryukyu studio glass.

Its compact scale makes it particularly versatile for collectors who appreciate fine craft objects that can be displayed individually or incorporated into a larger Japanese studio-glass collection.

Curator’s Note

This work is an excellent illustration of the philosophy that makes Seikichi Inamine's glass so distinctive: the transformation of glass into something that feels drawn from the natural environment itself. The warm mineral body evokes Okinawan earth and stone, while the sweeping cobalt and turquoise element recalls the surrounding Pacific waters. The two opposing visual languages meet within a single compact vessel.

For collectors of Japanese studio glass, the impressed 「吉」 marking adds another important dimension, providing a physical identifying feature that accompanies the artistic characteristics of the work. More than a drinking vessel, this is a small piece of Okinawan material culture interpreted through contemporary glassmaking-an object in which traditional chūfuki craftsmanship and modern artistic expression coexist naturally.
