Location: San Diego County, California

USBGN researcher Cheryl Cook believes this name is derived from a Temecula (Luiseño) Indian word Japa which Hanna described as meaning "prickly peat". Charles Hart in his Village Names of Twelve California Mission Records, notes a Diegueño Indian rancheria named Japacha listed in the records of Mission San Diego (n.d.).

Delisted from HPS Peak List because it was described as a "dinky little bump on the side of Cuyarnaca" and because the "point was below the summit" (1960).

Name first appears on USFS Cleveland National Forest map (1954).

Peak was added to the HPS Peak List in 1956.
