It is due to a Japanese law that states if any children of a specified age or lower, are able to watch the said show then it has to be censored. AFAIK. I remember Tokyo MX used to air late night versions of anime that was uncensored but that trend seemed to have stopped.
What I am waiting for so far:
Amagi Brilliant Park
Akatsuki Yona
Cross Angel: Tenshi to Ryuu
Donten ni Warau
Fate/Stay Night 2 (Reanimated and better storytelling from Ufotable)
Garo: hanno no Kokuin
Gundam Build Fighters Try
Gundam G
Hitsugi no Chaika
Log Horizon 2
Kiseijuu
Kaitou Joker
Inou Battle wa Nichijou-kei
Mushishi 2
Psycho-pass 2
Selector spread
Terra Formars
World Trigger
