Giboshi

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.
