This is a vintage Japanese cast iron pagoda lantern, likely from the mid-20th century, used for garden decoration or lighting. It features a distinctive curved, pagoda-style roof with a handle on top for carrying or hanging. The lantern has an aged rust patina on its cast metal body, which includes a hinged latticework door for inserting a candle or tealight. Typically standing on three legs, these decorative items are often referred to as "Sankyaku Tsuridoro" (tripod hanging lanterns).
