Gibōshi (擬宝珠) is a type of ornamental finial used on Japanese railings.^[1] Gibōshi bridge ornaments resemble an onion; the ends are bulbous and typically come to a point. It is believed that the shape of gibōshi was from hōju (宝珠; "sacred gem" or "cintāmaṇi") which is used to decorate roofs.^[2] They are often found on bridges in Japanese gardens, temples and shinto shrines.^[2]

Gibōshi come in two styles; normal style and Kamakura style.^[2]
