"AYAKA" is the first and only solo photobook released by Ayaka Kimura. The photobook was published by Wanibooks on August 21, 2003. The photography was done by Yoshimoto.
The title of the photobook is taken from Kimura's name and nickname, Ayaka.
The photobook shows Kimura being happy with a little seriousness. The photobook was also said to really show off her sweet side. The pictures were taken to illuminate her body and face. There were many shots of her in her bikini at the beach, since the theme of the photobook was summer. There were also shots of her in her kimono doing summer festival traditions, and her in summer-based clothes in forests and other green areas.
