How to say "longevity" in Japanese

• 長生きながいきCommon
  noun, suru verb, intransitive verbThe everyday word for living a long life: use it in ordinary conversation about someone who has lived to a great age, or when wishing someone a long life.
  妻つまは夫おっとより長生ながいきするものだ。↗

• 長寿ちょうじゅCommon

• 長生ちょうせいCommon
  noun, suru verb, intransitive verbA separate word, read ちょうせい, meaning long life; it is a word in its own right, not a form of 長生き, and in meaning it is closest to 長寿.
• 寿ことぶきCommon
  nounA celebratory word for long life, carrying an auspicious, festive ring; it is seldom the neutral word for 'longevity' — for that, 長生き or 長寿 is the word you want.

For longevity itself, use 「長生き」 in everyday conversation and 長寿 in formal or written contexts; 長生 is a separate near-synonym of 長寿, while 寿（ことぶき） is celebratory rather than neutral.
