The site, a 1.94 acres (0.79 ha) area, was listed on the National Register of Historic Places in 2016.

The NRHP nomination states:Chagui'an represents the intense suffering and hardship endured by the indigenous population (Chamorros) of the U.S. Unincorporated territory of Guam during the 31 month Japanese wartime occupation of the island.

The massacre site exemplifies the atrocities committed on Micronesian populations in the Pacific Theater of Operations and epitomizes the tragic extremes that can be inflicted on small, marginalized, native populations without political authority or the prerogative of military sanction in global conflicts.

Chagui'an is one of only a handful of war-related massacres of civilians that occurred on U.S. soil during World War II.
