Giboshi

Giboshi (擬宝珠^?) is a kind of ornament used on older Japanese bridges.

In Japan, giboshi bridge ornaments are said to resemble the bulbous flower of the onion.

The ends of giboshi are bulbous and come to a point, resembling the onion domes in Western culture.

They are often found in older Japanese bridges, and on bridges in Japanese gardens, temples and shinto shrines.
