no offence to anyone but I don't think that Miyavi is 185cm, honestly..
I saw him in real and he didn't look so taller than I thought before . He was like 183cm or so.yea actually he was tall but couldn't be 185cm. or he can be 185cm with his boots on?
in my eyes Maya was taller next to Miyavi.
as for Karyu I saw someone who is a huge fan of Karyu said he is 187cm like tokyo tower haha (it's also with boots on??) he looks really tall indeed though I'm not sure
I just found other tall ones :
Tora (Alice nine) 183cm
Tatsurou (Mucc) 183cm
Toshiya (Dir en grey) 181cm (wiki said hes 181cm but I think hes more taller)
