Early Life[]

Ogawa Saki was born on November 18, 1996 in Saitama, Japan to a couple whose names are undisclosed.


Ogawa Saki joined Hello! Project as a member of Hello Pro Egg in June, when she passed the auditions alongside 31 other girls.

In November 2005, Ogawa received a role in a musical as "Henrika" in "34 choome no kiseki" The musical ran from November to December.

In 2006, Ogawa continued her training and appeared at numerous Hello! Project concerts as a backing dancer, including the Country Musume concert "Country Musume LIVE2006 ~Shibuya des Date~".

In 2007, Ogawa was selected along with Okai Asuna to represent Hello Pro Egg in their collaboration with Kodansha's release of Mottainai Baasan Ondo. She also took part in television, "Chao.TV" (started 2007/09/02).

In November 2007, Ogawa was a part as a backing dancer for ℃-ute's "Cutie Circuit 2007 ~MAGICAL CUTIE TOUR~" concert.


On April 4, Tsunku announced on his blog that a new group, later named "S/mileage,"[1][2] was in the works.[3] The members listed were Wada Ayaka, Maeda Yuuka, Fukuda Kanon and Ogawa Saki. He stated the lineup was subject to change, and that it would be their "major debut".

From November 11 to 19, Ogawa starred in Koisuru Hello Kitty alongside the other S/mileage members and Mano Erina.


On February 18, Ogawa had her first solo event at Pacifico Heaven in Tokyo.[4] The fanclub event was a competition with all four members to see who would fill up the most seats in order to win another solo fanclub event.[4] Ogawa came in fourth place.[5] As part of her revenge, Ogawa had her second solo event on March 31.[5][6] After failing a second time, Ogawa had a 3rd solo event on April 30.

In April, Ogawa made her debut as a member of Oha Girl Maple, an idol unit made for the children's show Oha Suta.[7] With the Oha Girl tradition to have a unique challenge in every line-up, Ogawa was challenged to learn baton twirling during her time in the group.

In May, Ogawa and the rest of the S/mileage members graduated from Hello Pro Egg in the spring concert.


On August 24, it was announced that Ogawa would graduate from S/mileage and Hello! Project on August 27 at a live event for "Uchouten LOVE".[8]

Announcement from S/mileage Site[8]
Thanks for always supporting S/mileage.

We have an important announcement about S/mileage’s Ogawa Saki.

Following the Uchouten LOVE Live Event on August 27th at Higashi Betsuin Hall in Nagoya, Ogawa Saki will be graduating from S/mileage and Hello! Project.

Comment from Tsunku[8]
Thank you gratefully for your continual support of Hello! Project and myself.

Let’s get right to the announcement I want to tell you.

From S/mileage, who has recently gain 5 sub-members, Ogawa Saki will be graduating from S/mileage and subsequently from Hello! Project.

Early in May this year

“Earlier, I have been contemplated and consolidated with staffs, about returning to being a normal middle school student. I feel very strongly about this, please let me quit.”

She has made this request.

Even being the youngest in the group, I have entrusted her with her singing skills.

However, now, from here on and out, as a group and each member individually, their strong desires to improve persist.

Even as a producer, it’s not in the best interest of the group and members to continue to force a member in doubt to endure more group activities, therefore Ogawa’s request has been accepted.

It was officially announced at first that this unit’s member might increase or decrease, it was due this is reason that an urgent S/mileage member audition was held in June this year.

Due to various conditions of the group, herself and other parties involved, as well as terms and conditions on contract, it was not until today that this information and her will can be reported, please accept my apologizes.

Also, she is still an immature student.

A working adult would understand that abandoning work half way is an inexcusable act, but please consider her straight and strong feelings, and watch over her with your warm and love.

Therefore, all fans, please take care of S/mileage which is still in its infant stage.

For this hasty written letter as a report, please excuse me


S/mileage Producer


Comment from Ogawa Saki[8]
Thank you for always supporting me.

As of August 27, 2011, I, Ogawa Saki, will graduate from S/mileage as well as Hello! Project.

Since our major debut last year in May, I have enjoyed every single day as part of S/mileage.

However, somewhere down in my heart, I felt there was a gap between myself and the S/mileage me. I have talked it over with the staff many times and have been constantly worrying about it, and with everyone working their hardest to move forward and myself still uncertain of things, I decided that it was not in the best interest of S/mileage and I will return to being just a normal girl.

I apologize for the last minute announcement.

While there may be feelings of sadness, S/mileage will always be a group with it’s trademark smile!

I’ll be working my hardest to end with a smile until my last event on 8/27, I know there isn’t a lot of time left but I hope you can support me!

The new members will power up S/mileage after I graduate so I hope you’ll continue to support them.

Thank you very much for all your support up til now.
