内ない部ぶ闘とう争そう

I got caught up in the company's internal power struggle.

• 内ない紛ふん

  内紛 is similar but often implies a more open or disruptive internal dispute, while 内部闘争 is a broader term for any internal struggle.

• 内うち輪わもめ

  内輪もめ is a more colloquial term for family or small-group squabbling, whereas 内部闘争 is used for formal or organizational conflicts.
