The "Ichirin-sei" brass vase, crafted by Japanese master metal casting artist Shugoro Hasuda, is a work from his mature later period, possessing both artistic and collectible value. The vase is cast in brass with a matte sandblasted finish. The spherical body with a slender neck is decorated with three horizontal lines, reflecting Hasuda's typical "modern Japanese style" design language. Designed specifically for Japanese flower arranging (Ikebana), it can be used to hold a single flower, showcasing Eastern Zen aesthetics. The base bears his signature seal, and the vase comes with its original paulownia wood box, the lid of which features his handwritten inscription and red seal. An artist biography and explanatory notes are also included, making it a complete set for a masterpiece by a renowned artist.
