What are Japanese seasonal greetings?

A seasonal greeting ("jikō no aisatsu") is a formal phrase used to open a Japanese letter or business document, capturing the feel of the current season before the writer gets to the point. Built around the pattern "...-no-kō," these phrases describe a season's distinctive climate or imagery in a formal, classical-sounding register, showing consideration for the reader from the very first line. This tool lists the standard seasonal greetings for every month together with their reading and meaning, so you can look one up quickly when drafting an invitation, a letter of apology, or a note to someone of higher standing.

Because the weather shifts even within a single month, the correct phrase often changes between the first half and the second half of the month. A seasonal greeting is placed right after the opening salutation (such as "Haikei") and leads into a line wishing the recipient continued health or prosperity, with the letter finishing on a closing word that matches the opening one, such as "Keigu."

How to use this seasonal greeting list

  1. Pick a month Filter the list down to the month you are writing in, or the month your letter is expected to arrive.
  2. Choose a greeting from the list Compare the candidates shown and pick the one that matches the formality of your document and the actual weather.
  3. Check the reading and meaning Read the pronunciation and explanation so you avoid misreading or misusing the phrase.
  4. Pair it with an opening and closing word Place it right after an opening salutation like "Haikei," continue into the body text, and finish with a matching closing word.

Tips for getting more out of it

  • A seasonal greeting normally follows the opening salutation (like "Haikei") and leads into a line wishing the recipient prosperity, such as "...and I hope your company continues to thrive."
  • The word "kō" (候) means roughly "the season of," and appears at the end of virtually every seasonal greeting. Swapping it for "...no ori" or "...no migiri" produces an equally polite variant.
  • In everyday business email, seasonal greetings are often simplified into a season-neutral stock phrase such as "I hope this finds you well" rather than a month-specific expression.
  • For personal letters, choosing a phrase that matches the actual weather (e.g. "amid this lingering summer heat") rather than the strict calendar date tends to feel warmer and more sincere.

Frequently asked questions

Seasonal greetings are formal expressions reserved for official letters — invitations, letters of apology, ceremonial documents. In everyday business email, they're usually simplified into a plain opener like "Thank you for your continued support," without a season-specific phrase.

Weather can shift noticeably within a single month, so a different phrase is chosen for the first half versus the latter half. February, for example, uses "risshun-no-kō" near the start of the month and "yokan-no-kō" toward the end, matching how the actual weather is changing.

It's typically followed by a line wishing the recipient continued health or prosperity — for a company, something like "I hope your company continues to thrive"; for an individual, a wish for the wellbeing of "you and your family."

If you open with "Haikei," follow it with the seasonal greeting, then the body text, and close with "Keigu." If you open with the more casual "Zenryaku," the seasonal greeting is skipped entirely and the body text begins right away — that's the correct pairing.

Side Note — the uniquely Japanese custom of seasonal greetings

Seasonal greetings are a custom unique to Japanese letter-writing culture, expressing the changing seasons at the very start of a letter as a gesture of consideration for the reader. The practice is thought to trace back to Chinese classical letter-writing etiquette, and seasonal phrasing already appears in the correspondence of Heian-period court nobles. It spread among ordinary people during the Edo period through "ōraimono" (textbooks that taught letter-writing), and continued to be taught as a foundation of formal epistolary Japanese well into the modern school era.

Seasonal greetings are deeply intertwined with the "24 solar terms" (nijūshi sekki), a calendar system of Chinese origin that divides the year into 24 segments. Terms like "keichitsu" (the awakening of hibernating insects) and "risshū" (the start of autumn) are lifted directly from this system into greeting phrases — so learning to read seasonal greetings is also a way of learning Japan's traditional sense of the seasons.

While the spread of email and chat has reduced everyday use of letter-specific seasonal greetings, they still play an important role in formal documents — invitations, letters of apology, and correspondence with someone of higher status. Choosing the right seasonal phrase is still considered a marker of refined Japanese writing skill and cultural literacy.
