Thank you for viewing. I used AI to research this item as I was unsure of its details. It appears this commemorative item is a copper paperweight commemorating the inspection of His Imperial Highness Prince Kaninnomiya by the Osaka branch of the Japanese Red Cross Society in the early Showa era. It seems to have been created to commemorate an event held at the Osaka branch of the Japanese Red Cross Society in 1937 (Showa 12). It commemorates the inspection by His Imperial Highness Prince Kaninnomiya (Prince Haruhito Kaninnomiya). It is made of copper, weighs approximately 141g, and has a diameter of approximately 5.5cm. It is considered a valuable commemorative item related to the Imperial Family. The item has overall scratches. Please refrain from purchasing if you are looking for a perfect item, as this is a used item. Thank you very much!!
