BULLET TRAIN originaly had 8 member as they debuted in 2011 and than continued as 7 member after one droped out after 1 year. Later on in 2018 and 2020 another member left making them 5. In 2022 their company now added 4 new members to the group.
Till earlier of 2022 BULLET TRAIN only consisted out of Kai, Yuki, Ryoga, Takuya and Takashi, (with Sho, Koichi and Yusuke as former members) but now added the 4 new members called Shuya, Haru, Aloha and Masahiro.
BTW wtf is with the name Aloha? I hope thats not the dude's real name 
but there is not much info on the new members yet. Apparently the new member allready joined in August, but they just only released 2 days ago a new album with the new members added to it.
I wonder what their company thought of by adding them instead of just making a new group, since BULLET TRAIN exists for 11 years by now and never had member changes of adding new member despite that 3 member left the group over the years. IDK it feels just weird when groups ad new member after existing for so long
