tsuridōrō 釣灯籠

Also *kaitomoshi 掻灯. A lantern hung from the corner of the eaves of a building. They are usually small, 4-or 6-sided, and made from metal, copper or wood. The lantern is designed to fit under the overhanging eaves of the roof; the shape is often curved, with the portion under the flame holder being wider and the area above narrower. 

The lanterns have a long history dating back to ancient China. They were introduced to Japan in the Nara period for use in imperial palaces; later these hanging lanterns were called *tōrō 灯籠; they were also termed akashi 灯 and miakashi 御灯. Hanging lanterns exist today in the Seiryōden 清涼殿 and Higyōsha 飛香舎 of Kyoto Gosho 京都御所.
