Uchiki Co., Ltd. is an established company renowned for its traditional craftsmanship of Yamanaka lacquerware, notably the "Shima" cups. Their artisanal products combine the functionality of stainless steel double-walled glasses with Yamanaka lacquerware, creating items that are one-of-a-kind due to the nature of their craftsmanship, each exuding its unique beauty.

The "mirror finish," made possible by the skilled polishing techniques of Tsubame-Sanjo, adds an elegant touch to the dining table. The fusion of the "lacquer" of Yamanaka and the "polishing" of Tsubame-Sanjo is a rare combination, earning international acclaim under the name "Uchiki Shima." They have been selected as a "Takumi (Master Craftsman) Enterprise" by the Japan External Trade Organization (JETRO), and the collaboration between Yamanaka lacquerware and Tsubame-Sanjo craftsmanship is poised to receive even greater recognition in the future on a global scale.
