Elena Sasamiya (笹宮えれな / Sasamiya Erena) is a Japanese AV actress who debuted around 2015 (initially under the name Kato Aira / 加藤アイラ). She later worked as Sasamiya Erena, and has also been credited as Yuihaku Masaki (結白まさき) and Hazuki Shuri (葉月シュリ). She is known for her exotic features (sometimes described as having a mixed or half-Japanese look), tallish stature (reports of ~166–170 cm), and a voluptuous, full-figured body type that has varied across her career due to weight fluctuations and diet periods. She has appeared in dozens of titles (estimates of 70+ under various names, with higher totals including amateur/one-off works) for both major censored labels (such as Fitch, Mother/Muchi Muchi, WAAP, Planet Plus, and others) and uncensored platforms. She was particularly active in the uncensored scene from roughly 2018 onward. An interesting note is her name changes and continued activity under aliases into the early-to-mid 2020s, along with reports of body transformation over time that fans often discuss as a distinctive aspect of her filmography.
