- She is the only 10th generation member that has not had past experience in the entertainment industry.

- She began ballet in second grade to help her fix her posture. However, by the time she became a Morning Musume member, she had already quit.

- Michishige Sayumi said that one of her dreams is for her sister Aneshige and Sato to meet each other.
- Kudo Haruka said that Sato can communicate with aliens, while Oda Sakura finds Sato's disappearances a mystery, and believes that there is no person who could beat Sato in communication skills. Oda once said in an old interview that Sato could be the next evolution of the human race.
- Their manager asked her to make something with someone (from the management) for the 12th generation to practice their sense of rhythm. But before they could, she’d already made it all by herself: a CD of her own composition.
- Tsunku commented: "She keeps acting the youngest one, but she's quite clever. She's bad at studying, but somehow she has the ability to pull through, making her a smart girl in one way. But if she sees this she'll just think she's smart, and that's kinda scary... Work hard!"
- Oda Sakura said that Sato composes music at home like it's her side job, and even does some recording in the car.
- She uses an iPad application to create songs using drums, piano, and guitar. She added Oda Sakura's voice to a song and made her own version of "Fantasy ga Hajimaru" (Masaki Version) featuring Oda. Sato also does programmed drum beats, EDM, vocal things, key modulations.
- She had created her own song titled "Jinsei wa Iroiro Aru♪" (人生はいろいろあーる♪).

- She can imitate the singing voices of some aces and Hello! Project's best vocalists, such as Tanaka Reina, Fujimoto Miki, Sugaya Risako, and Sayashi Riho. Fans sometimes find it hard to distinguish her powerful vocals from Oda Sakura's vocals.
- Miyamoto Karin said on the au headline web show Idol Mou Icchou that Sato always says "I can't do it", but when things begin, she suddenly changes like someone else and works it out. Miyamoto thinks of herself as a hard worker who can achieve only by practice, while Sato is gifted by nature. Miyamoto declared: "I want to beat her gifted talent with my effort." The host (known as Gurasu-san, a fan of Sato as well) says Sato is in some respects a tensai (genius), which Miyamoto agreed with.
- Lyricist and musical teacher Niira Etsuko told the behind-the-scenes story about the song "Princess Margaret" from LILIUM -Lilium Shoujo Junketsu Kageki- in a YouTube video. According to her, the arrangement of the song was mostly done by Sato. The original demo was only 1:15~1:25, which Sato changed to 1:26~1:35. Niira said Sato is genius and you can't easily find someone like her in Japan. Sato was scolded for adding too much to the arrangement, but Niira says it's her fault because she's the one who approved it. Lastly, she said that changing other's work to the extent that you are scolded for it is amazing and that Sato hit the nail on the head musically. "From the point of view of normal Japanese woman or their peace-at-any-price principle, Maa-chan is the one who causes trouble... I can see why she likes Reina," she said with a laugh.

- Oda Sakura and Iikubo Haruna said that Sato mistook the lyrics in "Utakata Saturday Night!". Sato often sung the line is "ato mawashite" (後回して; put it off later) as "atama mawashite" (頭回して; turn your head), but has since begun to sing it normally. You can see her lipsync it like this in her solo version.
- Oda also said that Nonaka Miki's younger sister noticed this while watching the MV and asked Nonaka: "This part... did Sato-san sang 'atama mawashite', onee-chan?" Then they asked Sato directly and she said she really thought it was "atama mawashite".
- If she could be reborn as someone else, she would be Tsuji Nozomi. When they first met, the mama Tsuji was different from the Tsuji she saw on TV, and Sato would like to become a mother like her.

- In 20 years after 2017, Sato wants to be working beside Tsunku. She wants to teach songs to Morning Musume members, decide their concert stages and setlists, and become a producer.
