Prunus incisa, the Fuji cherry, is a species of flowering plant in the family Rosaceae, which gets its scientific name from the deep incisions on the leaves. It is an endemic species in Japan and grows wild in Kantō, Chūbu and Kinki regions. It is called the Fuji cherry because it grows in particular abundance around Mount Fuji and Hakone.Toshio Katsuki. (2015) Sakura. pp.170–173 Iwanami Shoten. {{ISBN|978-4004315346}} A dainty slow-growing, early white-flowering cherry tree, this century-old cultigen from Hondo, Japan is highly regarded as an ornamental but the wood has no industrial value. It is hardy to -20 °C, and crossed with Prunus speciosa, has yielded the cultivar Prunus 'Umineko'.{{cite book |last1=More |first1=D. |first2=J. |last2=White |year=2003 |title=Cassell's Trees of Britain & Northern Europe |publisher=Weidenfeld & Nicolson |page=535 |isbn=0304361925}} It is in the ornamental section Pseudocerasus of the cherry subgenus Cerasus of the genus Prunus. Ma et al. classified it in a group with Prunus nipponica.{{cite journal|last1=Ma|first1=Hongmei|last2=Olsen|first2=Richard|last3=Pooler|first3=Margaret|journal=Journal of the American Society for Horticultural Science|title=Evaluation of Flowering Cherry Species, Hybrids, and Cultivars Using Simple Sequence Repeat Markers|year=2009 |pages=435–444|volume=134|issue=4 |doi=10.21273/JASHS.134.4.435|url=http://naldc.nal.usda.gov/download/37581/PDF|doi-access=free|url-access=subscription}}
