1st week sales, #9 on overall Oricon book charts, 17,836 copies.
For reference, her first photobook [Mayuyu], released 13th May 2011, sold 45,209 copies on it's first week on sale
Going to also compare to the aces of the sister groups:
Matsui Rena: 26,492
Yamamoto Sayaka: 27,622
Watanabe Miyuki: 29,800
I'm not really surprised by the low sales of this photobook - her first photobook was brilliant, had a large variety of photos, and displayed her
assets well. This photobook has small paper size (A5) and is severely lacking in variety - just school uniforms, school sportsday...
