A Different Sound After Sunset

Summer in Japan has its own powerful soundscape.

For many people, one of its most recognizable sounds is the loud chorus of cicadas.

Their calls can fill parks, temple grounds, residential neighborhoods, and tree-lined streets during the hottest part of the year.

But the seasonal soundscape does not remain the same.

As summer moves toward autumn, other insect voices become increasingly noticeable, especially in the evening and at night.

Crickets and other singing insects call from grasses, gardens, fields, and roadsides.

This is not a sudden change.

There is no single evening when the sounds of summer disappear and the sounds of autumn begin.

The seasons overlap.

Some summer sounds remain while others gradually become more noticeable.

And little by little, the night begins to sound different.

Sometimes autumn reaches your ears before it reaches your eyes.

Why Are Insect Sounds Connected with Autumn?

Insects make sounds in many parts of the world.

So the insects themselves are not uniquely Japanese.

What is interesting is the cultural attention that certain insect voices have received in Japan.

For centuries, the sounds of singing insects have appeared alongside autumn in Japanese poetry, literature, seasonal imagery, and other forms of cultural expression.

Their voices became one of many ways of recognizing the season.

This does not mean that every person in Japan hears an insect and experiences exactly the same emotion.

Seasonal associations are never that simple.

But Japanese culture has provided a long vocabulary of images and experiences through which people can notice seasonal change.

Flowers can suggest a season.

A particular food can suggest a season.

The moon can suggest a season.

And sound can too.

That is why an insect calling from an ordinary patch of grass can carry more than biological information.

In the right moment, it can also say:

Autumn is approaching.

Listening to Insects Has a Long History in Japan

The connection between insect voices and autumn is not a recent invention.

Japanese literature has described people listening to autumn insects for centuries.

Their voices appear in classical poetry and literary works, where sounds from grasses and gardens help create the atmosphere of an autumn evening.

Over time, listening to singing insects also became an activity people could deliberately enjoy.

The important point is not that people simply knew these insects existed.

They paid attention to their voices.

A tiny creature hidden in the grass could become part of the experience of a season.

That gives us another way to think about seasonal culture in Japan.

Appreciating a season does not always require a spectacular landscape.

Sometimes it begins with noticing something very small.

The Insects Behind the Autumn Soundscape

Several insects are especially familiar in discussions of autumn sounds in Japan.

One is:

鈴虫 — suzumushi

Usually called the bell cricket in English.

Its Japanese name contains the character 鈴 (suzu), meaning “bell,” reflecting the association between its clear call and a ringing bell.

Another is:

松虫 — matsumushi

Another well-known singing insect associated with autumn.

And then there are:

コオロギ — kōrogi

Crickets whose calls are commonly heard in grassy places and around everyday environments.

There are many species, and you do not need to identify each one to experience the seasonal soundscape.

In fact, when walking outside on a September evening, you may never see the insect making the sound.

It may remain completely hidden.

You only hear its voice.

And perhaps that is part of what makes the experience distinctive.

The source is small and almost invisible.

But the sound can fill the night around you.

Why Does the Same Sound Feel Different in September?

A seasonal sound does not exist by itself.

Think about everything else that is changing around it.

The sun is setting earlier than it did in midsummer.

The strongest heat of the day eventually gives way to evening.

There may be moments when the air feels slightly cooler.

The intensity of summer is beginning, slowly, to loosen its grip.

Then you hear insects calling from the grass.

The sound becomes part of everything else you are already noticing.

A sound becomes seasonal partly because of everything happening around it.

This is why the arrival of autumn can be difficult to place on a single date.

You may notice it through several senses at once.

The air.

The light.

The length of the evening.

And the sounds coming from somewhere you cannot quite see.

None of them needs to announce the new season alone.

Together, they begin to change the atmosphere.

You Can Hear Autumn Without Knowing the Insect

If you visit Japan in September, you do not need to become an expert on insects.

You do not need to know whether every call belongs to a suzumushi, matsumushi, or another kind of cricket.

Simply listen.

Try a quiet residential street after sunset.

Walk beside a river or through a park.

Listen near grassy areas, gardens, or temple grounds.

The exact sounds will depend on where you are, the weather, the time, and the insects living nearby.

But the point is not to complete a checklist.

It is to notice whether the evening sounds different from the daytime — or from the summer you imagined.

This is one of the easiest seasonal experiences to overlook because there may be nothing obvious to photograph.

No famous temple is required.

No mountain covered in red leaves.

No ticket.

No reservation.

Sometimes all you need is a quiet evening and a few seconds of attention.

Autumn Is Not Always Red and Gold

Images of Japanese autumn often show the season at its most dramatic.

Maple leaves glowing red around a temple.

Golden ginkgo trees lining a city avenue.

Mountains covered in autumn color.

Those scenes are real, and they are beautiful.

But they represent only one part of the season.

If you wait for red leaves before looking for autumn, you may miss many of its earlier changes.

September offers a quieter version.

Autumn may be present in a breeze that lasts only a moment.

In evening light.

In grasses beside a river.

And in voices coming from the darkness.

Before autumn changes the color of Japan, it begins changing its sound.

Listen Before You Look

The next time you experience early autumn in Japan, do not search only with your eyes.

When evening comes, stop for a moment.

Listen beyond the traffic, footsteps, and ordinary sounds of daily life.

There may be another layer underneath them.

A small repeating call from a garden.

Several voices rising from a riverbank.

An insect hidden somewhere in the grass.

You may not know its name.

You may never see it.

But perhaps you will recognize what the sound is telling you.

The season is beginning to change.

Japanese even has a familiar expression for these voices:

虫の音 — mushi no ne

The sounds — or voices — of insects.

In the next article, we will look more closely at this expression and what 音 (ne) adds to the way these sounds are described in Japanese.

For now, simply listen.

What sound tells you that a new season has arrived where you live?
