Imuta-ike (藺牟田池) is a freshwater caldera lake in Satsumasendai, Kagoshima Prefecture, Japan.

This is very rare in warm areas and the pond was designated a Natural Monument as the "peat forming vegetation of Imuta-ike" in 1921.

As for fish, species include Zacco platypus (Oikawa (追河)), Black bass, Carassius langsdorfii and Oryzias latipes.

A rare dragonfly, Libellula angelina is found, leading to the pond's selection as a Ramsar Site.

Prior to the Taishō era (1912–1926), Imuta-ike was known for the growth of common rushes (Juncus effusus), the raw material for tatami mats.
