Not sure if it's been mentioned yet, but Maki Goto has a book called Ima no Watashi Wa『今の私は』coming out October 5th and is doing a handshake event at HMV books Shibuya on October 7th. Additional tickets have been made available to the handshake event due to popular demand.
This is most likely why we're seeing her on variety shows more lately.
