How to say "mole" in Japanese

• ほくろCommon
  nounCovers the small dark spot on the skin. Since it is usually written in kana alone, write it without kanji; it can also suggest a charm-like beauty mark.
  あの人ひとは眼めの横よこにほくろがある。↗

  That person has a mole at the side of his eye.
• 防波堤ぼうはていCommon
  nounIn the sense of 'mole' this means the breakwater protecting a harbor. For the everyday meaning of 'mole' (a skin spot or the animal), this is not the word you want.
  波なみが激はげしく防波堤ぼうはていにぶつかった。↗

  The waves dashed against the seawall.

For the skin blemish use 「ほくろ」; for the harbor structure use 防波堤. The two senses are unrelated, so pick according to whether you mean a mark on the skin or a breakwater.
