How to say "self-centred" in Japanese

• 身勝手みがってCommon
  na-adjective, nounThe everyday word for someone who acts as if they alone matter, disregarding those around them; it covers both 'selfish' and 'self-centred' and is the default choice in most contexts.
  彼かれの身勝手みがってな態度たいどに腹はらを立たてた。↗

  His selfish attitude put my back up.
• 手前勝手てまえがって
  na-adjective, nounA four-character compound covering the same self-centred, selfish sense as 身勝手, but less common; learners will seldom need to produce it, though it is worth recognising.
• 一人勝手ひとりかって
  na-adjectiveLess common than 身勝手, this emphasises doing as one pleases without consulting anybody else — hence 'very selfish'; it fits someone who decides or arranges things entirely on their own.
• 狷介けんかい
  na-adjectiveReally means obstinate, stubborn or headstrong; its 'self-centred' gloss is secondary, so it is seldom the word you want for ordinary selfishness — use it when unyielding stubbornness is the point.

For everyday 'self-centred' selfishness use 身勝手; 一人勝手 stresses acting without consulting anyone, 手前勝手 is a less common four-character equivalent, and 狷介 really means stubborn rather than selfish.
