The Old Japanese Name for August

In ancient Japan, each month had a poetic name inspired by nature, daily life, and seasonal change.

August was called Hazuki (はづき / 葉月).
You can still find this beautiful seasonal name on traditional calendars and in classical literature today.

Meaning of Hazuki (はづき / 葉月)

Although the name literally contains the character for “leaf” (葉), it does not refer to the fresh green leaves of summer.

One popular explanation is that it comes from:

  • 葉落ち月 (ha-ochi-zuki) – “the month when leaves begin to fall”

Over time, the pronunciation is thought to have changed into Hazuki.

From this, Hazuki is often understood as:

“The Month When Leaves Begin to Fall.”


Why “the month when leaves begin to fall”?

At first, this may seem surprising.

August is still hot across much of Japan, and trees remain green.

However, according to the traditional calendar, Hazuki falls later in the season, when the first signs of autumn begin to appear.

People started noticing small seasonal changes, such as:

  • the earliest leaves beginning to fall
  • cooler mornings and evenings
  • insects singing more actively
  • hints that autumn was slowly approaching

Rather than marking a dramatic change, Hazuki celebrates the quiet beginning of a new season.


Cultural Meaning

Hazuki carries a feeling of gentle transition.

It represents:

  • noticing the first signs of autumn
  • appreciating subtle seasonal changes
  • enjoying the final days of summer
  • looking ahead to a new season

In modern Japan, August is also associated with:

  • summer festivals
  • fireworks
  • family holidays
  • the Obon festival
  • fields glowing under the summer sun

Even during the hottest days, nature quietly begins preparing for autumn.


Originally inspired by Chinese traditions

Like many traditional month names, Hazuki was influenced by ancient Chinese calendar systems.
Over time, however, Japan shaped the name through its own seasonal observations and appreciation of nature.

Today, Hazuki reminds us that the seasons rarely change all at once—
they begin with small, beautiful signs that reward those who take the time to notice them.
