Nogizaka46 member Takayama Kazumi has joined Instagram (@takayama.kazumi.official).
On April 21, Takayama hosted a show on SHOWROOM to commemorate the paperback release of her novel 'Trapezium' (April 24). This is where she announced that she would be opening an Instagram account. In one of her posts, she explains where the title of her novel came from, "My editor and I came up with a bunch of titles to decide on temporarily. The final two were 'trapezium' and 'rectangle,' so we went with 'trapezium.'"
