The season the dead come home

Today marks the start of obon (お盆), a custom distinct to Japan. Originally an ancestral rite observed over several days centered around the fifteenth day of the seventh month of the lunar calendar, it is now most commonly held in mid-August of the solar calendar. At this time of year, people return in great numbers to their hometowns, and the cities empty out. In the countryside, relatives gather to welcome family returning from the cities and to remember their ancestors. Through this, the scene of family gathering together—something now rapidly disappearing—temporarily returns, and in rural areas in particular, most shops close. Anyone traveling through Japan at this time should be aware that outside major tourist spots, almost nothing is open.

Customs of obon that developed distinctively in each region are also celebrated in various forms as festivals, including bon odori (盆踊り) dances. While these began as rites to welcome the spirits of ancestors, today they tend to function largely as commercial spectacles aimed at drawing tourists. Even in Tokyo, it was once customary to bundle dried hemp stalks into torches and light them as waymarkers so that the spirits would not mistake their homes. In an era without electricity, fires of welcome flared across town, guiding ancestral spirits back home. That landscape has vanished, and many now regard obon merely as a summer holiday; yet it remains an essential season for remembering those who came before us.

In Japan, obon was observed on the fifteenth day of the seventh lunar month, but with the Meiji era it shifted to the solar calendar, and today most companies schedule their holidays in mid-August. During this period, city dwellers set off on a massive migration known as the homecoming rush. The origins of obon, however, trace back to the mid-sixth century, when Buddhism arrived in Japan via China, bringing with it the Indian rite of urabon (盂蘭盆). The root of urabon lies in Indian Buddhism, grounded in the story of Maudgalyayana (known in Japan as Mokuren), a disciple of the Buddha, as recounted in the Urabon Sutra. Seeking to save his deceased mother from suffering in the realm of hungry ghosts, Mokuren pleaded with the Buddha for her salvation. The Buddha instructed him to offer food and drink to monks on the fifteenth day of the seventh lunar month and transfer the resulting merit to his mother. Mokuren did as he was told, and his mother was freed from her torment. It was from this episode that the annual urabon-e (盂蘭盆会) arose in India: an offering to the monastic community on the fifteenth day of the seventh lunar month to rescue deceased parents and ancestors.

Translated into Chinese, the term became urabon, deriving originally from the Sanskrit ullambana, which carries the sense of hanging upside down in agony. In the course of its transmission through China, the rite fused with Confucian filial piety and Daoist beliefs in spirits, undergoing a complex transformation before reaching Japan in the Asuka period. In Japan, it further merged with ancient ancestral beliefs and folk practices, developing into a uniquely Japanese obon. Modern obon still holds Indian elements at its origin, yet almost no visible trace of them remains; it is better understood as an entirely different cultural creation.

According to the Nihon Shoki, in the fourteenth year of Empress Suiko’s reign (606), an observance called the "gathering of the hour" was established at each temple on the fifteenth day of the seventh lunar month. This is regarded as the first recorded instance of urabon-e in Japan, showing that it had already taken root as an imperial court observance. By the Nara period, it was instituted as an annual event of state Buddhism: around the fifteenth day of the seventh lunar month, memorial rites for imperial ancestors were conducted at court and in official temples. This incorporated Buddhist ancestor worship into state ritual, serving the dual purpose of protecting the realm and venerating the imperial ancestors.

By the Heian period, urabon-e had established itself firmly in aristocratic society, and mentions of comforting ancestral spirits appear in court diaries and tales. Over time, it spread to the common people, joining with Japan’s indigenous ancestor veneration to evolve into the distinct custom of obon. During this season, it was believed that the spirits returned home. People guided them with welcoming fires and sending fires, setting up a shoryodana (精霊棚), a spirit altar, laden with seasonal vegetables, fruits, and dumplings. Monks also made rounds from home to home chanting sutras before these altars, a practice called tanagyo (棚経). In this way, obon separated from urabon, transforming its meaning into the form we know today.

From the Kamakura to the Edo period, obon permeated village communities across the country, becoming the centerpiece of common life. Performing arts such as bon odori were added, and dancing through the night served not only as entertainment but also as a way to bind communities together and provide a setting where young people could meet their future spouses. Representative traditions that survive today—such as the Shoro Nagashi in Nagasaki, the Gozan Okuribi in Kyoto, the Awa Odori in Tokushima, and the Eisa in Okinawa—all grew out of these historical obon rites. The modern homecoming rush itself has its prototype in the Edo-period practice of yabuiri (藪入り), when servants were granted leave to return to their family homes at the New Year and obon. For the townspeople of Edo, Kyoto, and Osaka, it was a vital time spent with family.

It was after the Meiji Restoration that this historically nurtured current of Japanese culture underwent a profound shift. Once again, it becomes clear how decisive a turning point the Meiji Restoration was in sundering Japan's historical continuity.

The waves of Westernization and modernization after the Restoration deeply affected obon customs. With the adoption of the solar calendar in 1872 (Meiji 5), the observance moved from the fifteenth day of the seventh lunar month to July 15 or August 15 of the solar calendar, bringing confusion as dates diverged across regions. In parts of eastern Japan, the "new obon" (shinbon, 新盆), observed in July, took hold, while across western Japan and much of Tohoku, the "month-delayed obon" (tsuki-okure bon, 月遅れ盆) centered on August 15 became mainstream. This division was partly a choice made to match agricultural schedules, climate, and local rhythms of life, but it also reflects the fact that these regions belonged to different cultural spheres.

Modern urbanization went on to transform everyday lifestyles and how obon was spent. People who had migrated from farming villages to the cities began returning home at obon to visit family graves, and during the postwar era of rapid economic growth, this large-scale seasonal migration became a defining social phenomenon known as the homecoming rush, continuing to this day. Behind it lay the postwar expansion of railway and highway networks, which helped establish obon nationwide as an annual gathering for families and kin. In addition, because August 15 marks the anniversary of the end of the Second World War in Japan, the day came to be felt as a solemn occasion where mourning for the war dead overlapped with ancestral rites.

From the late twentieth century onward, regional bon odori and festivals drew attention as tourism resources and grew into events celebrated nationwide. Tokushima’s Awa Odori, Akita’s Nishimonai Bon Odori, Fukushima’s Soma Nomaoi, and Okinawa’s Eisa now draw crowds of visitors to areas that are otherwise quiet at that time of year. In the cities, by contrast, the custom has tended to simplify into quiet family visits to graves or prayer before the household Buddhist altar. In recent years, under the weight of nuclear families, depopulation, and an aging society, large-scale community obon rites have dwindled, and people increasingly regard the period merely as a holiday. Yet at the same time, movements by municipalities and cultural groups to preserve and revive traditional rites are gaining strength. Since the pandemic, new forms such as online memorial services and remote grave visits have emerged as people seek memorial practices suited to the times—though these, too, are signs of cultural decline.

In contemporary obon, not everyone is acutely conscious of its religious roots, yet its core—a time to remember ancestors and confirm family bonds—remains unchanged. In gestures such as the welcoming and sending fires, offerings, and visits to graves, the view of ancestral spirits held by the Japanese for more than a thousand years continues to breathe. The idea of urabon, born in Indian Buddhism, altered in China, and fused in Japan with ancestral belief, continues to live on in modern society, changing its form as it goes.

In today's society, where faith in ancestors has drifted away from daily life and finding a place of belonging in the city has become difficult, this season feels as if the ancient ancestors are trying to tell something to those of us who, since Meiji, have let go of what matters most. And around this time, as night falls, the summer heat begins to ease, and the subtle signs of the typhoon season begin to stir.

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 season the dead come home”, first written on 9 August 2025. Why do the dead come home at Obon? When ancestral faith drifts from daily life, belonging in the city is hard, Takahiro Mitsui argues, and obon is when ancestors speak — Obon from the Indian Urabon through China to Japan's ancestor faith.

In “The season the dead come home”, Takahiro Mitsui writes about Obon, ancestor worship, Buddhism transmission and Meiji calendar reform.

Takahiro Mitsui's thesis: Obon merged the Indian Urabon story of Mokuren with Japan's ancestor faith, and was shifted to the solar calendar in the Meiji era (SJ 187, published 2025-08-09).

Takahiro Mitsui: "The modern subject called "I" believes it stands alone, but we are only one part, at this moment, of a band woven of the ancestors. Through ancient ancestor worship and the Obon that flowed into it, this sensibility poured the sense of "not being the subject" into the bodies of the Japanese over thousands of years." (Equality is a meeting with your life at stake, 2026-08-12)

Takahiro Mitsui's thesis: Obon came from the Indian Urabon story of Mokuren through China to Japan, where it merged with ancestor belief (SJ 187).

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: “Whenever those who came before us fell into such a predicament, when nothing more could be done by their own strength, they always found their way out by moving their bodies.” (Project 2049 Vol.4, https://project-2049.takahiromitsui.com/vol-4 )
