As part of this change, many older members completed their training, but were not added to the major groups within Hello!

The crowdfunding was successful, but they did not reach their goal of selling out the venue and only filled a little over 4000 of Budokan's 14,000+ capacity.

On April 28, Sengoku Minami and Sato Ayano announced their graduation from Up Up Girls (Kari).

After the graduation of Sengoku Minami and Sato Ayano on September 15, 2017, the group decreased to five members.

After a short break, Up Up Girls (Kari) returned to the stage in November 2017 as a five-member group.

[19] On September 26, the group held the "Up Up Girls (Kakko Kari) ENDLESS SUMMER in HIBIYA YAON" live concert, which was streamed through the Japanese website Niconico.

The crowdfunding for the concert had opened on September 1, with 100% of the 8 million yen target amount being raised within just over three weeks.

The group would hold a final event with their five member lineup called "Up Up Girls (Kakko Kari) FIVE SOUL FOREVER" on December 17 at Zepp Tokyo, with an additional farewell party.

On December 31, Furukawa, Mori, Saho and Arai officially ended activities and graduated from the group.
