Yuko Oshima (大島優子) getting ready to celebrate her 25th birthday today!

Happy birthday to Yuko-san, my favorite member of AKB48! Since Mariko Shinoda was graduated from AKB in July, she became the oldest member of the 48s with Haruna Kojima.

She won the best newcomer actress award on 2013 Japan Academy Award in March.
