Kohshi went to university in Yokohama and is actually a math teacher.
He is writing the lyrics for B'z and underwent a lot of different looks throughout his carreer. Long hair, short hair, long hair...he also wears the latest fashion, which, looking back on the 80s might look strange ("hotpants", need I say more ?).
Kohshi likes dogs and wants to be a breeder once retired. He even gave his dog a guest appearence on his solo album (the barking in "jealous dog").
Kohshi's birthplace is the destination of many B'z "pilgrims" .
His Mama has a little shop with B'z memorabilia and will tell you all kinds of stuff about her son .
Go to Tsuyama to see Kohshi's old house, his school and so on (we have a video about it in the video-section). Even though the place seems to be in the middle of nowhere, it is busy due to all the (female) fans, especially when rumour has it that Kohshi is there.
Three things he can't live without :
contact lenses, notebook (I know I know, those are only 2 things >-< )
Inaba san's "nickname" is 178 (japanese: Ichi Nana Hachi = Inaba).
He married twice and his baby son was born in the summer of 2002.
