Nuphar subintegerrima is a species of rhizomatous aquatic plant endemic to Japan.

Nuphar subintegerrima has emerging or floating leaves. The leaves are 5-11 cm long, and 4-8.5 cm wide.

The pedunculate, solitary, yellow flower extends above the water surface. Ripe fruit detach from the plants.

It reproduces vegetatively through its rhizomes.

It reproduces sexually. Flowering occurs from May to November.

It was first described by Robert Caspary as the variety Nuphar japonica var. subintegerrima Casp. in 1866. It was elevated to the species Nuphar subintegerrima (Casp.) Makino by Tomitaro Makino in 1910.

It occurs in streams, bogs and irrigation ponds.

It is pollinated by the fly species Notiphila maritima.

The larvae of the moth species Neoschoenobia testacealis feed on leaves and flower stalks of Nuphar subintegerrima.
