TRAN PARAN’s innovative “Re Ochawan” (or “Re Bowl”) rice bowl has won the prestigious 2023 Social Product Award. The “Re Ochawan,” born from the desire for eternal earthenware, combines eco-friendliness with exquisite craftsmanship. By incorporating a powder made of discarded tableware into the clay and glaze, this rice bowl offers a sustainable alternative that benefits both the earth and pottery-producing regions.

Mino ware from Gifu Prefecture is considered Japan’s largest ceramics production base. The pottery-making process relies on resources like clay, feldspar, and silica, formed over eons by the earth’s environment. Yet, it’s plagued by three problems: environmental impact, unstable clay supply, and non-biodegradable waste.
The “Re Ochawan” addresses these issues head-on. By repurposing broken or unwanted tableware as components of new rice bowls, it creates a circular economy for ceramics.
The Japanese are no strangers to ceramic rice bowls. By shedding light on the overlooked issue of ceramic waste disposal and fostering collaborations, TRAN PARAN strikes a chord with consumers. Eloquent design, artisanal quality, and transparent recycling rates further bolster its appeal.
