Naomi Osaka's ten nearest neighbors by audience shape are activists, academics, civil society organizations, and journalists — not other athletes. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 0.96 indicates near-identical audience profiles.

The top 10 form a tight band running from 0.96 down to 0.94, consistent with the flat shape classification. Shaun King (0.96) and Bernice King (0.95) are the two activists in the set; Melissa Harris-Perry (0.94) and Cornel West (0.94) represent academics. Civil society anchors the cluster through NAACP (0.95) and Color Of Change (0.94), both organizations. Michelle Obama (0.95) is the lone politician; Soledad O'Brien (0.94) the lone journalist. Ava DuVernay (0.96) rounds out the set as an artist. The Undefeated (0.94), a sports and culture website, is the only media property in the top 10 — and the only entity with an explicit sports connection. No other athlete appears in the top 10.

The cluster's character is civic and cultural rather than athletic: the audience Osaka draws looks most like the audiences following activists, academics, and advocacy organizations, with scores compressed into a narrow range that signals a coherent, well-defined community rather than a diffuse one.
