Sexy Otonajan (セクシーオトナジャン) was one of the three Hello! Project shuffle units formed in 2005, along with Elegies and Puripuri Pink. “Jan” is a slang term used at the end of an adjective or noun to make it sound more cool and casual. Their unit's theme was "sexy."

- Tsunku made the following comment about this unit on his blog:
- This unit has the best potential of all, in my opinion. The leading member is Miki Fujimoto, and I added 2 girls who possess the most matured images among “Hello!Project Kids”. My dream finally came true for the new unit with sex appeal, and I named the unit as “Sexy Otona Jan”. I personally want this unit to succeed for a long time, but it’s just my selfish opinion. Lol. The song is ‘bossa-nova’ style, which reminds you of the romantic summer nights that grown-ups would enjoy by the beach. Please indulge yourself in this atmosphere. Special thanks to Yoshiko Miura who provided the lyrics for this song.
- Eight years after its original release, their song Onna, Kanashii, Otona was featured as a background track for the 2013 movie The Wolverine.
