This is a hand-painted matcha cup made by the renowned Kutani ware craftsman "Nidai Kosei," a piece that combines artistic value with Japanese aesthetics. Craftsmanship and Creator: Handcrafted by the master Kutani ware craftsman "Nidai Kosei," this cup utilizes the wood-firing technique (resulting in a glaze with the natural texture and rustic feel characteristic of wood-fired pottery). It features hand-painted decorations—a "Ugly Ox" motif on the body and an image of "Old Man of Longevity" on the inner wall, along with auspicious Japanese calligraphy such as "Fuku no Kami" (God of Fortune). The style blends folk charm with refined literati elegance. Shape and Size: A typical Japanese matcha cup, its shape is round and full, with a textured, coarse pottery body. The bottom bears the maker's signature and seal, typical of Kutani ware. It is both a practical tea ceremony utensil and, due to the master craftsmanship of "Nidai Kosei," possesses high artistic and collectible value, representing a masterpiece of traditional Japanese ceramics.
