Translation of "Truthfully" in Japanese

Truthfully, hip-hop is one of this generation's biggest perpetrators,

本当のところ ヒップホップは 当代きっての主犯格に入ります

Truthfully, in order to wear the badge of authentic masculinity,

正直に言うと 本物の 男らしさの印を得るためには

Yes, truthfully, until it was right in front of me like this, I half-doubted it ...

ああ、オレも実際、こうして目の当たりにするまでは半信半疑だったが・・・。

Truthfully, if I'd said I didn't have any regrets over my snap decision I'd have been lying.

実のところ、即決を悔やんでないといったら嘘だった。

Truthfully, at that time, I didn't have the first idea about such talk: family links, blood relations or whatever.

正直なところ、その当時の僕は血縁がどうとか、続柄がどうとか、そういう話はまるで理解出来ちゃいなかった。
