1. Profile & AV Debut (Piloted Under Multiple Aliases)

Mayu Horisawa is a Japanese AV actress born on April 3, 2001, in Fukushima Prefecture. She has performed under names including Mayu Horisawa, Yasuda Hitomi, and Kaname Ria (Ria Kaname). She stands 155 cm tall with measurements 87‑58‑85 cm (F‑cup)—a petite yet prominently curvaceous appearance. She made her debut in 2021 with adult video releases under these aliases

2. Cheki Photos: Very Limited or Absent in Public Listings

There is currently no publicly confirmed evidence of published or circulated signed cheki photos (Instax/Polaroid-style memorabilia) featuring Mayu Horisawa. Unlike AV idols who frequently host cheki sessions or events, her presence in cheki distribution remains extremely rare or nonexistent in resale platforms or auctions.

3. Collectible Appeal (Hypothetical & Future Value)

Given her relative newness to the industry and limited known cheki output, any signed or event-issued cheki featuring her—if released—would be considered exceptionally rare and potentially highly valued among collectors. Scarcity and uniqueness often drive collectible pricing higher, especially for idols with small distribution footprint.
