Beauty clinic Takasu Clinic has been asked by multiple patients whether or not AKB48 member Kashiwagi Yuki's breasts are natural, prompting the clinic to release a statement on the topic.

After fans began comparing photos from last summer to swimsuit photos taken in 2011, speculation that Kashiwagi had gotten plastic surgery to increase her cup size started spreading around the internet. Because of this, questions came pouring into the office wondering if "Yukirin" had ever consulted Takasu Clinic for silicon breast augmentation.

In response to this, Takasu Clinic director Takasu Mikiya asserted that "as a doctor, (he is) 99.9% sure that she has not had (breast augmentation) done".

Takasu went on to point out several reasons why she could not have had surgery within that time span: the idol hasn't had the time between lessons and live performances to visit the clinic, and is not a suitable candidate for breast augmentation by fat or hyaluronic acid injection due to her already thin build.
