How to say "infamous" in Japanese

• 悪名高いあくめいたかいCommon
  i-adjectiveCovers the core sense of infamous: widely and unfavorably known. It is the common, default choice for people, places, or incidents famous for bad deeds or a bad reputation.
  その悪名あくめい高たかい犯罪者はんざいしゃは昨日きのう逮捕たいほされた。↗

  The notorious criminal was caught yesterday.
• 破廉恥はれんち
  na-adjective, nounReally means shameless or disgraceful conduct, so it matches infamous only on that side. For the 'famous for bad deeds' sense it is seldom the word you want, and it is less common.
  破廉恥はれんちな人間にんげんは自分じぶんの母ははさえも裏切うらぎるだろう。↗

  An unscrupulous person would sell even his own mother down the river.
• 札付きふだつき
  no-adjectiveDescribes a person whose bad reputation is fixed and well known — notorious, and hardened in it. It is less common, and it characterizes the person rather than a deed, event, or place.

Choose 「悪名高い」 for the general 'widely known for bad things' sense; 破廉恥 stresses shameless, disgraceful conduct rather than notoriety itself, while 「札付き」 describes a person whose bad reputation is firmly established.
