How to say "ubiquitous" in Japanese

• 普遍ふへんJLPT N1approx.Common
  no-adjectiveThe noun for the idea itself: universality, what holds true everywhere. It suits abstract or philosophical discussion; for the everyday 'found everywhere' sense of ubiquitous, this is seldom the word you want.
• 普遍的ふへんてきCommon
  na-adjectiveThe adjective form: use it when you want to say something — a truth, value, or principle — is universal, holding everywhere. For concrete things that are simply found everywhere, it is not the natural pick.
  それには絶対的ぜったいてきで普遍的ふへんてきな意味いみはない。↗

  It has no absolute and universal significance.

Both words cover the abstract side of 'ubiquitous' — universal, omnipresent, holding true everywhere: choose the noun 普遍 for the concept of universality, the adjective 普遍的 to describe such things, and look elsewhere for concrete 'found everywhere'.
