Hatanaka Yoshikazu Shoten Co., Ltd., founded in 1887 and based in Taka Town, Hyogo Prefecture, is a long-established company known for producing konjac sponges. Their signature product, Tsuyano Tama, is made from natural materials using a traditional method that takes over two months, resulting in a sponge that offers a gentle and soothing cleansing experience for the skin.
This sponge has excellent water affinity, and its fine konjac fibers effectively lift away dirt and excess oil without the need for scrubbing—just warm water is enough for a refreshing cleanse. It is especially popular among those with sensitive skin and those who prefer natural skincare solutions.
While preserving its traditional techniques, the company continues innovating to meet modern demands. Its products have received high praise both in Japan and abroad.
