Japewia is a genus of lichen-forming fungi in the family Lecanoraceae. The genus was circumscribed in 1990 by the Norwegian lichenologist Tor Tønsberg, who assigned J. tornoënsis as the type species. The new genus is named in honour of Peter Wilfred James, a notable lichenologist, with Japewia being derived from the first letters of his initials (Ja) and his surname (Pe) followed by a typical Latin suffix (-wia).
