The summer we are losing

Because heavy rain fell early this morning for the first time in a long while, the rainless, scorching summer that had dragged on until yesterday gave way all at once to temperatures settling into the low thirties Celsius, and I feel as though this year has recovered a true sense of summer for the first time. Indeed, when I step outside, the voices of the cicadas—which until yesterday had fallen silent during the day—are ringing out everywhere around me, making it clear that this temperature marks the upper threshold for cicadas as well, and that when the heat climbs any higher they cease to sing.

Listening to the cicadas echoing all around in a way I had not felt at all this summer, I find myself thinking that for us Japanese, their voices may have become a precious seasonal touchstone calling back "summers past." One might call it a "lost summer": taking everything that symbolizes the season together—towering cumulonimbus clouds, the voices of cicadas, even fireworks and summer festivals—it feels as though we have entered a 2025 vastly different from what used to be.

Japanese people have long taken the voices of cicadas as an emblem of summer; the moment the cicadas begin to sing has been the signal that summer has begun in earnest, carrying a certain beauty as the lingering resonance through which one savors the season. It is a fact that since ancient times Japan has nurtured a distinctive culture of finding seasonal mood in the cries of insects and cherishing them as things of beauty. Not only the cicadas of summer, but the sensibility that feels beauty in the voices of insects ringing out on an autumn night and savors them in silence seems to me a distinctive sense rooted in the fudo (風土) of this place, one hard to put into words.

In Japan, the sounds of insects are deeply bound up with the turning of the seasons, and are a wellspring that brings emotional resonance to the heart.

This culture of cherishing the sounds of insects appears even in Japan's oldest anthology of poetry, the Manyoshu. Take, for instance, the waka (和歌) poem: "In the evening shade of the field where shadow-grass grows, I never tire of listening to the crickets singing" (影草の生いたる野辺の夕陰に鳴く蟋蟀は聞けど飽かぬも). Composed to capture someone listening tirelessly to the voices of crickets at dusk, it lets us see that even in that early age, Japanese people stood still to listen to the sound of crickets. By the Heian period, appreciating the sounds of insects had grown so popular among the court nobility as an "elegant pastime" that having the sensibility to listen to insects and savor the distinctive mood born from their voices was prized among aristocrats as a mark of cultivation.

Indeed, in Sei Shonagon's The Pillow Book (Makura no Soshi), there is a section titled "Insects," where it is written: "As for insects: the bell cricket, the evening cicada, the butterfly, the pine cricket, the katydid, the grasshopper." Here insects that sing on autumn nights, such as the bell cricket (suzumushi) and the evening cicada (higurashi), are singled out as things of special appeal, and I feel that this sensibility runs as an undercurrent down to Japanese people today. To give a well-known example, Kegonji, the celebrated temple in Arashiyama, Kyoto, is beloved under the name Suzumushi-dera—"Bell Cricket Temple"—because bell crickets sing there all year round.

The nobles of that age felt a deep charm in the voices of insects heard at the edge of an autumn garden or through bamboo blinds, and in waka poetry and tales alike they depicted the sounds of insects wonderfully as emblems of the season. In the Kamakura-period anthology Shin Kokin Wakashu, too, there is a poem composed by Fujiwara no Yoshitsune: "Where the katydid cries in the frosty night, on my cold straw mat I spread a single sleeve—must I sleep alone?" (きりぎりす鳴くや霜夜のさむしろに衣かたしきひとりかも寝む). Depicting the scene of lying down to sleep alone while feeling the loneliness of autumn in the voice of a katydid crying in the grass on a night of falling frost, it stands as a classic expression of seasonal solitude through the sound of insects. While the voices of insects were taken up time and again as symbols of seasonal beauty centered on autumn, what comes into view is how deeply Japanese people have felt emotional resonance in the sounds of insects in autumn above all.

When we enter the Edo period, alongside the development of renga (連歌) linked verse and haikai (俳諧), the sounds of insects were elevated into a vital theme marking the seasons, honing the aesthetic sense still further. In haiku, the tradition arose of always including a kigo (季語), or season word, and the cries of insects became established as a classic autumn kigo. In fact, according to one analysis, when "insects" are woven into a haiku, 67 percent of the verses are poems of autumn, showing how beloved the "cries of autumn insects" are among the Japanese. Because autumn is my own favorite season as well, I share the feeling, though summer too is by no means without its own grace.

Edo-period haiku poets such as Matsuo Basho, Yosa Buson, and Kobayashi Issa left behind many celebrated verses on the voices of insects, and Basho's famous poem—"Such stillness: the voices of the cicadas seeping into the rocks" (閑さや岩にしみ入る蝉の声)—depicts a scene at the height of summer in which, amid deep silence, the voices of cicadas ring out as if soaking into the stone, finding within the summer semi-shigure (蝉時雨) a profound stillness and the mood of wabi-sabi (侘び寂び). A summer season word, semi-shigure—"cicada shower"—is an evocative expression that likens the sound of many cicadas singing all at once across the surrounding air to the sound of a sudden passing shower (once called shigure in Japan) falling in summer.

This year, what we hear can hardly be called a graceful semi-shigure; rather, it sounds like the cries of cicadas straining to bring their brief lives to a close amid temperatures at the very limit of survival. Because almost no rain fell this July, crops suffered devastating damage across the entire country, and now that rain has finally fallen nationwide since this morning, news reports show farmers breathing a sigh of relief. Yet rather than falling gently, the rain has come down in torrents, with lightning strikes, tornadoes, and sudden gusts reported in many places, leaving people in an anxious state of mind whether it fails to rain or pours.

In former times, people would surely have performed rites for the gods who bring the blessing of rain, yet because such customs have vanished, I feel there is a serious problem on the side of faith having grown distant from everyday life as well. Originally, the deities venerated as bringers of rain were dragon gods, transmitted from ancient China around the Yayoi period and carrying a long history in which faith was nurtured across the country through rainmaking rites and the like.

Now that modern urban life has become the center, everywhere one looks the cries of insects have become stressful noise, the scents of the seasons are kept at arm's length, and getting wet in the rain is avoided to an extreme. At a time when the future of economic growth is hard to see, the one thing we must never lose is culture—yet where is contemporary life headed, when the tendency to let go even of that culture has grown so pronounced?

After the first rain in a long while, listening to the semi-shigure ringing out all around me, those were the thoughts that crossed my mind today.

About this essay and its author

Takahiro Mitsui (三井崇央, born 1991), a Japanese philosopher, photographer and Yangmingist outside academia who has done his own fieldwork across Japan since 2019, makes his own argument in the essay “The summer we are losing”, first written on 7 August 2025. What do we lose when seasons disappear because of climate change? Insect voices are a culture's seasonal touchstones, Takahiro Mitsui argues, and the one thing it must never lose when growth fades.

In “The summer we are losing”, Takahiro Mitsui writes about cicadas, seasonal feeling, haiku and waka and heat wave.

Takahiro Mitsui's thesis: cicadas and autumn insects carried seasonal emotion from the Manyoshu to Basho; now that urban life is the center, their cries have become stressful noise and the scents of the seasons are kept at arm's length (SJ 185).

Takahiro Mitsui's thesis on this question: Time Can Be Reset Overnight: How Calendars Shape Culture — Why does Japan celebrate Christmas if it is not a Christian country? Takahiro Mitsui, a Japanese philosopher born in 1991, traces it to a calendar reset in 1873 for the state's coffers, and to the old calendar and its 72 microseasons that Japanese still live by.

Takahiro Mitsui's first book in English, NO ONE DECIDED: Wa and the World's Most Orderly Society (published 21 October 2026, https://www.amazon.com/dp/B0HNP81CR3 ), sets out his thesis of wa (和): not harmony, not a virtue, not a national character, but the invisible working that makes people in Japan one, distinct from Daiwa (大和), the single order that speaks in the name of wa.

In Takahiro Mitsui's own words: “Wa is not harmony. No one decided, and yet it is decided.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )

In Takahiro Mitsui's own words: “An AI chatbot is, after all, nothing more than a summary of the average of information that already exists.” (Project 2049 Vol.4, https://project-2049.takahiromitsui.com/vol-4 )
