This is a redesign of the kurojyoka, a traditional Kagoshima shochu ceramic teapot, to fit modern lifestyles. The traditional Kurojyoka was formed based on the Japanese hearth heating system, and its shape has remained the same despite changing lifestyles. This project is a continuation of Kagoshima's shochu culture and traditional craftsmanship by modifying this aspect and updating the kurojyoka to fit modern lifestyles.

The fact that the shape has been modified for the modern age.

Production Technology
The redesigned Kurojyoka has a mass produced design so that it can be used as a modern earthenware teapot for shochu and as an everyday household item for enjoying shochu. It is made using casting molding, a technique for mass producing ceramics, in which muddy ceramic clay is poured into a plaster mold.
The material is porcelain, which is durable and can be used for commercial purposes.
The glaze uses shirasu from the Shirasu Plateau, a characteristic of Kagoshima's soil, with the aim of it becoming an everyday household item made from local materials.
Design Challenge
In redesigning the Kurojyoka, we tried to make it a mass production type for easy general use, but there was a difficulty in that Kagoshima does not have mass production technology. Therefore, we asked a Nagasaki potter with mass production technology to manufacture the product, but used Kagoshima materials for the glaze, thereby creating a Kurojyoka with elements of the production area.
Project Duration
The project began in Kagoshima in February 2018 and ended in November 2019 and has been sold.
Inspiration
The project began with a request from MATHERuBA, which operates a cafe and store in Kagoshima, to redesign the Kurojyoka, a traditional Kagoshima porcelain earthenware teapot for shochu, to suit modern lifestyles and create an original product.
We therefore researched the origin of the shape of Kurojyoka for shochu traditionally used in Kagoshima, and found design inspiration in the abacus shape described in literature, which we redesigned into a shape that fits today's lifestyle.
