Before Koichi left the group, he wrote the lyrics for the song 'the end for beginning'. The tour's name was also named after the song. And then after that 'the end for beginning' tour, he left the group on 16 January 2018 due to the difference in goals.
Koichi is a really good singer, and his voice harmonises well with Takashi's.
His laughter is also really unique.

MESSAGE
As always, we appreciate your support for Choutokkyuu.
We apologize for the sudden news, but it has been decided that Koichi will be leaving the group.
He has been active as a back vocal for Choutokkyuu since 2011, but after having discussions with him about what he would like to do in the future, his goals were different from what the group wanted to achieve, and after taking everything into consideration, we have arrived at the decision to let him stop his activities as a member of Choutokkyuu.
To all the 8Gousha, we deeply apologize for the sudden announcement.
Although Choutokkyuu and Koichi will now be walking separate paths, Choutokkyuu will not halt their activities and will still be chasing after their dreams with all the 8Gousha, running on the rails to their dreams while facing even more challenges.
As to when Koichi will leave the group, we have yet to finalise everything, but at this point in time, with regards to the already finished shoots, it will be the 7 of them appearing. However, as for the already announced 1st single in 2018, only 6 members will be in it.
Concerning the 2018 spring arena tour (Sweetest Battle Field), only the 6 members will participating in it.
