How to say "peak" in Japanese

Choosing the right word
  • ピークCommon
    nounA loanword covering both the top of a mountain and figurative or statistical high points, such as traffic, demand, or performance reaching their peak. Natural in conversation, business, and weather or news contexts.
    朝あさのラッシュは今いまがピークだ。↗
    The morning rush is at its peak now.
  • 盛りさかりJLPT N3approx.Common
    noun, noun (suffix)Refers to the height or busiest point of a season or activity — the peak of summer, cherry blossom season, or when something is in season or full bloom. It does not refer to mountain tops.
    桜さくらの花はなは4月がつが盛さかりだ。↗
    The cherry blossoms are at their best in April.
  • 頂上ちょうじょうJLPT N3approx.Common
    no-adjectiveThe concrete top or summit of a mountain or hill. This is the usual everyday word for the physical peak you can stand on, and it is generally not used for figurative high points.
    私達わたしたちはついに頂上ちょうじょうへたどり着ついた。↗
    At last, we reached the summit.
  • 峰みねJLPT N1approx.Common
    nounA mountain peak, summit, or ridge, with a slightly literary or descriptive feel. It suggests a pointed summit or a line of peaks, and is not used for figurative or seasonal high points.
    その峰みねは雲くもの上うえにそびえている。↗
    The peak rises above the clouds.
  • 最高潮さいこうちょうCommon
    nounA figurative word for the climax, zenith, or apex of excitement, tension, or activity. It is not used for mountain tops, so it only matches the non-physical senses of 'peak'.
    試合しあいは最高潮さいこうちょうに達たっした。↗
    The game came to a climax.

For physical mountain tops use 頂上 or 峰; for seasonal, climactic or figurative high points choose 「盛り」, 最高潮, or the loanword 「ピーク」, which also covers mountain tops.
