This is a lucky charm, a wooden Uchide no Kozuchi (magic mallet). I obtained it quite a while ago for my son's Hatsumiyamairi (Shinto shrine visit celebrating a baby's first month of life) as a good luck charm symbolizing wealth and good fortune, and also as an amulet for good health. I used to display it in the tokonoma (alcove in a traditional Japanese room). Size: Approximately 9.5cm (height) x 5cm (width) Weight: Approximately 40g If anyone is interested, please let me know.
