According to lastnames.myheritage.com, here is the origin and meaning of the Awaragi last name.

The surname Awaragi has its roots in Japan, where it is believed to have originated from the combination of native Japanese elements. The name is thought to derive from the word awaragi, which can be associated with the concept of to be in a state of confusion or disorder, reflecting a historical context where names often described the characteristics or circumstances of the family. The surname likely emerged in the Edo period (1603-1868), a time when many Japanese surnames were formalized, and families began to adopt names that reflected their geographical origins or occupations. Awaragi may have been associated with specific regions or clans, indicating a connection to local governance or agricultural practices, as many surnames in Japan are tied to the land and its stewardship.

Culturally, the surname Awaragi may have variations in spelling and pronunciation, particularly as it has been transliterated into different languages. In regions outside Japan, such as in the United States or Brazil, where Japanese immigrants settled, the name may have undergone phonetic changes or adaptations to fit local linguistic patterns. However, the core meaning and cultural significance often remain tied to its Japanese origins. The spread of the surname can be attributed to migration patterns, particularly during the late 19th and early 20th centuries, when many Japanese moved abroad for work or to escape political turmoil.

Notable figures associated with the surname Awaragi are less documented in mainstream historical narratives, which may reflect the commonality of the name among various families rather than a singular prominent lineage. However, the cultural contributions of individuals bearing the surname, particularly in the arts, agriculture, or community leadership, may have played a role in shaping local identities and preserving cultural heritage. As with many Japanese surnames, the legacy of Awaragi is intertwined with the broader historical context of Japan's social and economic transformations, particularly during the Meiji Restoration and subsequent modernization efforts.
