Project concerts that Berryz Kobo would be going on an "indefinite suspension starting Spring 2015". The girls decided together that they would like to explore other opportunities. The decision to call this an "indefinite suspension" was made since the girls felt calling this move a "disbandment" would cause Berryz Kobo to disappear or fade away. The group continued its activities until the spring of 2015, when their final appearances and performances would be announced and take place. Tsunku added he would "like to see them chase new dreams" and asked for continued support throughout their remaining time as an active group.

The following day Kumai stated on her blog that she would finish her university degree and would pursue a modeling career.
