Uno Soyo ceramic kōgō and Japanese nerikō (incense balls)

In the art of Japanese incense, the kōgō is a small, precious box that preserves and enhances nerikō, refined incense pellets made from precious woods and spices. Together, they embody a sensory tradition characterized by elegant gestures and subtle fragrances, which Atelier Ikiwa is proud to celebrate with a carefully curated selection of superb kōgō, including this piece by ceramicist Uno Soyo, accompanied by a box of nerikō to introduce this little-known art.

The artisan
This kōgō was created by Uno Soyo (1888–1973), an eminent Kyoto ceramicist who specialized in kun glazes, celadon and purple glazes derived from research into Song dynasty jun firing techniques. Trained at the Kyoto Municipal School of Arts and Crafts and later at the Municipal Ceramic Laboratory, he devoted his career to the in-depth study of high-temperature glazes, mastering their delicate nuances and characteristic gradations. Recognized by Japanese cultural authorities for the importance of his techniques and the need to document them to ensure their transmission, he helped redefine Kyoto celadons in the 20th century. His works, often awarded at international exhibitions and distinguished by national honors, have been included in various public collections, reflecting his exacting research into color and light.

Technique and decoration
This kōgō depicts a stylized small crane, a lucky motif associated with longevity and good wishes. Its rounded body and slightly raised head evoke the bird in a calm posture, typical of the soft forms favored in chanoyu to create a discreet yet expressive presence. The glaze is a kun glaze, a technique inspired by high-temperature celadons, in which an iron-oxide-rich base and carefully controlled reduction firing produce a milky celadon blue with subtle variations. The bluish hues result from the glaze’s reaction in the kiln, creating the subtle color transitions characteristic of kun glazes. The piece is signed at the base with the ceramicist’s seal.

The nerikō
If you wish to enjoy the kōgō as intended, a box of nerikō is also included. This box contains thirty-six nerikō pellets, each made from a delicately scented blend based on sandalwood, created by one of Kyoto’s oldest incense houses. To use them, place two or three in the kōgō and leave the lid slightly ajar. To stop the fragrance from spreading, simply close the lid. Replace the nerikō pellets when they become dry. It is important to keep unused nerikō in the hermetically sealed plastic bag to prevent them from drying out.
