- For her, the hardest thing about being a Hello Pro Kenshuusei was not receiving any lines in "Oheso no Kuni Kara Konnichiwa".

- She wants to work as a model and idol at the same time.
- Tsunku's commented on Sasaki in late 2013: "Your dancing has gotten better. Because of that, I want your singing to get better, too. Within that, the details in feeling the rhythm, like we always say, and the feeling of conscientiously putting your heart into it. That feeling might be the part you're lacking the most. Your expressions are big, like "look at me!" and that's a good thing."
- According to an interview in JUNON magazine released in July 2014, Sasaki hoped on getting an orange member color.
- She admires Kudo Haruka because even with her husky voice she does her best to sing.
- She is the first ANGERME member to be born in the 21st century.

- She'd like to go to a haunted house with Kudo Haruka.
- She and former Morning Musume member Sayashi Riho are born on the same day.
- In Fukuda Kanon's final interview before her graduation, she had this to say about Sasaki: "She’s just so cute. Just having Rikako around brightens up a room. She has a rare gift and I hope she continues to invigorate ANGERME from her (sic) on, too."
- She shares the same last name as Up Up Girls (2) member Sasaki Honoka.
