Berryz Koubou member Sugaya Risako turned seventeen on April 4th!

"Thank you everyone," the idol wrote on her official blog, along with a picture of her birthday cake. "I'm aiming to be a charming woman."

Morning Musume's Michishige Sayumi also posted a blog entry about Sugaya's special day. "Yesterday, April 4th, was Berryz Koubou's Sugaya Risako-chan's birthday? I texted Risako-chan 'happy birthday', and shamelessly sent her (texts) until I got a picture. Here's that picture," she wrote beside a picture of Sugaya posing with her cake.

Fans commented, "Rii-chan, happy birthday!", "You'll be in trouble if you get any more charming," and "From now on, show us more kinds of Rii-chan!"

Happy belated birthday to Sugaya Risako!
