On November 9, two days after Juice=Juice's first concert at Nippon Budokan, Takagi wrote on her blog that during the concert her voice cracked a few times and she could not control her breathing properly which resulted in her not being able to sing high notes the way she wanted. She admitted that this was because of a vocal cord nodule she has had for quite some time, but because of the group's tour and other work there was no time for her to have surgery and rest afterwards. Takagi was able to finish the Budokan concert safely, and after thinking about it to herself and speaking with her family and the staff, she decided it was the best time for her to finally undergo removal surgery. She had just returned from the hospital and would not able to speak for a couple of days or sing for three weeks after the surgery.
