Case (Inrō) with Design of Seated Monkey Looking at a Wasp (obverse); Crabs with Fan beside Waves (reverse) 19th century

This 19th-century inrō, a traditional Japanese container for small items, was created by the renowned artist Mori Sosen. The inrō features two distinct scenes: one depicts a seated monkey observing a wasp, while the other portrays crabs beside waves and a fan. The intricate details and realistic portrayal of the animals are characteristic of Sosen's style, known for his mastery of the "kacho-e" genre, which specializes in depicting birds and flowers. The inrō serves as a miniature showcase of Sosen's talent for capturing the beauty and essence of nature.
