Rare Vintage Japanese Glass Fishing Floats

Glass Fishing Floats: Unique Collectibles from the Pacific Ocean

Glass fishing floats were originally used by fishermen worldwide to keep their nets, longlines, or droplines afloat. These hollow glass balls or cylinders, made to provide buoyancy, were commonly used by Japanese deep-sea fishing industries from as early as 1910. Today, most remaining glass floats found in the Pacific Ocean were made in Japan, with some originating from Taiwan, Korea, and China.

Handcrafted by glassblowers using recycled glass—often from old sake bottles—these floats feature unique air bubbles and imperfections. Identifying marks, sometimes including kanji symbols, were often embossed while the glass was still hot. Though no longer used in modern fishing, these beautiful glass floats have become popular collectibles for beachcombers and decorators, prized for their original netting and maritime history. Perfect for home décor, water gardens, or lanai spaces, these rare finds add a touch of nautical charm and heritage to any setting.
