Hypoptychus dybowskii, the Japanese sandlance, is a species of hypoptychid fish found in shallow salt water off the coasts of Japan and Sakhalin (Russia) as well as possibly occurring in South Korea and China. It is a commercially important species where it occurs. This species grows to a length of 10 centimetres (3.9 in) TL. This species is the only known member of its genus.[1]

Like sticklebacks, it feeds on small invertebrates and fish larvae. Also like sticklebacks, it produces a sticky secretion from its kidneys when breeding. The parent uses the secretion to attach the eggs to sargassum.[2]
