Blyxa japonica grows exclusively submersed, in shallow ponds, in swamps and slow-flowing woodland rivers rich in iron, in subtropic and tropical regions of East and South-East Asia. Throughout its area of distribution, it can also be found in rice paddies. This Blyxa species has become a very familiar plant in the aquarium hobby due to its attractive, grasslike, bushy habit.

Its cultivation is not especially difficult, if some basic requirements are met: sufficient light (0.5-1 watt per litre or more), CO2 supply and fertilisation with nitrate, phosphate, potassium and micronutrients. When cultivated in optimal conditions and under sufficient light, the plant displays golden and reddish hues and a more compact growth habit. Under insufficient light, B. japonica grows higher and greener, with a more lanky habit.
