Yamada Nana graduated from NMB48 on April 3, 2015. She has supported NMB48 for about four and a half years since October 2010, as a first-year student up to a team captain. Nana’s memorial photo book “4 + 3 = 7” is completely visualized! Like the memorial photo book with shootings in local Osaka, Namba, and Okinawa; this movie is full of highlights from swimwear to school uniforms.
