A carefully selected mixed set of 7 authentic Japanese hand-blown glass fishing floats, collected in northern Japan. This attractive lot includes two rare cylinder-type floats (rolling-pin style) and five spherical floats, showcasing a harmonious range of traditional sea-glass colours. Notably, this set features floats with original Japanese markings, including a clearly legible Kanji mark “川口” (Kawaguchi) and a Katakana mark “シ”, both highly appreciated by collectors as indicators of regional production and genuine working use. These floats were traditionally used by Japanese fishermen from the early to mid-20th century, particularly along the northern coastal regions such as Hokkaido and Tohoku. Japan was one of the earliest countries to adopt glass fishing floats, beginning production in the early 1900s as a durable and buoyant alternative to wooden and cork floats. By the 1930s–1960s, Japanese hand-blown glass floats were widely used not only throughout Japan but also across the Pacific. Many traveled overseas through fishing networks and ocean currents, later becoming treasured collector’s items. Each float was individually mouth-blown, resulting in natural bubbles, tool marks, swirling glass textures, and slight asymmetry. These features clearly distinguish genuine working floats from modern decorative reproductions. The cylinder-type floats included in this set were typically used for longline or net stabilization and are considerably rarer today than standard spherical examples.
