The flower that no longer comes on time

This year, the subtle shifts of planetary climate change have made themselves felt even in the texture of daily life. The abnormal summer heat that set in with a tropicalized rainy season around May brought home to me that Japan has already lost its four distinct seasons and is settling largely into two: summer and winter. In an ordinary year, mid-October would bring the calm, cool air of autumn, a time when people turn quietly to their books and adjust their bodies with seasonal foods as they ease gently toward winter. Yet even now, daytime temperatures in the cities along the Pacific coast still climb toward thirty degrees Celsius, and a walk outside leaves one sweating. Denied a gradual transition in keeping with the season, both mind and body are thrown into severe instability, and illness follows. Because the distress of a single person cut off from the turn of the seasons spreads simultaneously across urban populations, society itself inevitably grows unstable, and I cannot help sensing that Japan, too, is moving steadily toward deep division.

These effects show themselves not only in human health, but in a single flower. Sensitive and honest to the turning of the year, many plants have since ancient times bloomed only at a fixed point in the calendar, serving the Japanese as markers of the changing seasons. Because those markers answered not merely to shifts in the weather but to movements of the heart, a great deal of culture and art grew out of this attunement before modernity severed the city from nature. Cherry and plum blossoms are the classic heralds of spring, while the flower that announces the arrival of autumn is the red spider lily — higanbana (彼岸花).

Sending up its unmistakable crimson along the ridges between rice paddies, the higanbana has long been known as a flower that blooms without fail on the autumn equinox. Yet as I traveled through various regions this year, I found remarkably many places where it had not bloomed at all during this season. As its Japanese name indicates, higanbana takes its name from higan (彼岸), the Buddhist term for the other shore — the Pure Land of enlightenment, free from worldly desires and suffering. In Japan, higan is one of the seasonal markers of the traditional calendar: two seven-day periods each year, fourteen days in all, centered on the spring and autumn equinoxes with three days before and three days after. An old everyday proverb says that "heat and cold alike last only until higan," making it less a Buddhist observance than a vital signal of the turning season. To reach higan, in other words, originally meant the end of winter or the end of summer, and the higanbana, bursting into bloom right on cue, was its living emblem.

In a normal year, temperatures begin to fall gradually after the Obon period in mid-August, and by the time of shubun (the autumn equinox), the flower stalks of the higanbana shoot up from the earth. This year, however, the plant could not keep pace with an erratic climate, leaving many regions with the eerie sight of higan arriving without a single higanbana in bloom. Other anomalies are underway as well. In the mountain districts I still visit frequently for fieldwork, mosquitoes that would ordinarily have vanished by this time of year are still swarming in vast numbers. Global climate change is already remaking whole ecosystems at a speed that far outstrips our imagination. What I personally find most unsettling of all is the behavior of typhoons. Several typhoons normally strike the Japanese archipelago directly between late August and October, leaving damage across the country, yet for some reason their impact this year has been extremely limited. It is evidence that some immense shift is taking place on a planetary scale, and I find it deeply uncanny.

Since the Meiji era, when Japan abandoned its highly developed lunisolar calendar for political convenience and adopted the Gregorian calendar suited to an industrialized society, the great majority of contemporary Japanese — living as they do in the cities of the Pacific industrial belt — have paid almost no attention to these ecological transformations. Yet the bulbs of the higanbana have judged that it is "not yet autumn," altering or holding back their blooming period as they begin to adapt to a changing climate. Modern humans, by contrast, have not only failed entirely to adapt; they continue to live by a calendar that ignores the turn of the seasons, pouring their energy into keeping a zombified industrial society alive. Though we face a climatic shift of a magnitude seen only once in several centuries, or several millennia, urban life has wholly severed and stripped us of the chance to feel the breath of nature. In cities such as Tokyo and Osaka in particular, a "concrete-first" society forged in collusion with the political vested interests of the Liberal Democratic Party's postwar one-party dominance has robbed people of the very opportunity to register the signals sent out by natural ecosystems. Anyone who visited Tokyo or Osaka this summer will know that the root cause of the heat waves gripping the Pacific coastal cities lies in the high-rise office towers and residential blocks thrown up recklessly along the waterfront in defiance of natural order. This vast, chaotic wall of concrete blocks the wind from the sea, trapping the cities in abnormal heat waves, nauseating humidity, and sudden linear rainbands. These are not natural disasters. They are human-made disasters.

Even as nature begins to respond to planetary change and sends out signs at every turn urging human beings to do the same, urban dwellers treat those signs as though they did not exist, seeing nothing beyond the maintenance of an unalterable system and losing sight of themselves in the process. That is where we stand today. I am not suggesting simply that Japan ought to return to the old calendar. Rather, we need to rethink a way of living that draws on a distinctively Japanese capacity: holding two calendrical worlds — two orders of time and space — at once, and moving rapidly back and forth between them. The ecosystems of the natural world are teaching us precisely this. As I pursue these thoughts day by day, traveling back and forth between the city and nature, and between the present and antiquity, I find myself noticing things that would ordinarily pass me by. Among them, what has occupied my mind most of late is the relationship between the Japanese and alcohol.

Across the country, the rice harvest has come to an end, and communities are entering the season of festivals held to celebrate the crop and offer thanks to the gods. These rites mark the transition into winter, and in former times this was the season when farmers, having finished their great labor of the year, were at their liveliest. Just as late November brings the Niinamesai (新嘗祭), the rite in which the spiritual power expended by the emperor over the course of the year is restored by the gods, this spiraling, nonlinear way of living — an alternation of expenditure and renewal — was surely one of the finest elements of ancient Japanese culture. At shrines across Japan, one frequently sees offerings of rice presented to the gods at this time of year, and at shrines dedicated to deities of brewing, offerings of sake as well. I came across several such scenes again this week, and yet a question lingered in my mind. Since the start of this year I have been studying precision nutrition on my own, and recent advances in genetic analysis, together with clinical findings, have made it clear that a large proportion of Japanese people in fact have little or no tolerance for alcohol.

Strictly speaking, a lack of alcohol tolerance involves the ALDH family of enzymes, which metabolize the acetaldehyde produced along the histamine metabolic pathway, and above all ALDH2, which plays a central role in breaking down alcohol. ALDH2 falls into three genotypes: GG, known as the wild-type homozygote; AG, the heterozygote; and AA, the mutant homozygote. Because the GG type carries no mutation, those who have it handle alcohol well; the vast majority of white and Black people belong to this group, as do roughly half of the Japanese population. Its risk is that high metabolic capacity makes it easy to drink to excess, predisposing people to alcoholic cirrhosis or pancreatitis, though normal enzyme activity allows acetaldehyde to be broken down efficiently. Known as the predominant type among Westerners, GG is reported in Japan to be especially common in prefectures with deep-rooted drinking cultures, such as Yamagata, Akita, and Kagoshima.

The heterozygous AG type, meanwhile, accounts for roughly 40 to 45 percent of Japanese. With enzyme activity at only 30 to 50 percent, people in this group carry a heightened risk of esophageal cancer even without heavy drinking, and they have a moderate intolerance that causes their faces to flush easily when they drink. Finally, there is the mutant homozygous AA type. People with this genotype cannot drink at all; mere contact with alcohol can turn their bodies bright red, and because ALDH2 enzyme activity is almost completely absent, their capacity to break down acetaldehyde is exceedingly low. Even a few sips bring on facial flushing, headaches, palpitations, and nausea. Roughly 5 to 10 percent of Japanese fall into this extremely alcohol-intolerant group, a genotype now known to be concentrated among East Asians — above all Japanese, Chinese, and Koreans. Among Westerners, by contrast, the AA type is virtually nonexistent, which makes it difficult for them to fathom why anyone would be unable to drink at all.

When we bring these findings together, an unexpected picture of Japanese history begins to emerge. To take my own case, I am an AA type with no tolerance whatsoever, and I never touch alcohol. This has nothing to do with the "sober curious" trend now popular among younger people in the West; I literally cannot drink a single drop. Yet here is where the story grows interesting. Looking at my parents, my father drank heavily for decades, and my mother handles alcohol remarkably well. By the ordinary rules of genetic inheritance, someone born to a father who is AG and a mother who is GG — both on the tolerant side — should not end up wholly unable to drink, and yet I am AA. I also have two younger brothers, and the three of us are split to extremes: the middle brother is a GG who can outdrink anyone, while the youngest, like me, is an AA who cannot drink a drop. How could this be?

One key, I think, is that the Japanese relationship with alcohol — much like the rise of the "sober curious" movement even among predominantly GG Western youth — is at root less about alcohol itself than about a pushback against human relationships mediated by drink, and against the social systems that have fostered them. My father is a textbook example. Born and raised in an age of abundance as Japan hurtled forward through rapid economic growth, he spent the prime of his career in the bubble economy. Working in the client-driven advertising industry, he had client entertainment almost every night; for decades he worked day and night and drank until dawn, so much so that I scarcely remember him being at home when I was a child. Looking back now through what I have learned of precision nutrition, I can see that my father was never naturally strong with drink. He was an AG who learned to drink because the social environment of Japan at the time demanded it — a temporary adaptation of the body that would exact a heavy toll later on. Roughly ten years ago, in fact, he spent about a year battling stage-four cancer, and although he recovered, his health remains persistently unstable, with serious disruptions now emerging in his alcohol metabolism itself.

My mother, on the other hand, appears to be a natural GG: she is extraordinarily strong with alcohol and never gets drunk no matter how much she drinks. The reason lies with my maternal grandfather. He was born into a wealthy farming family in Akita Prefecture, a region with a deep history of sake brewing, where heavy snows once cut villages off for nearly half the year and left people with little pastime other than drinking. The inhabitants of that region have historically had a formidable tolerance for alcohol, and even as a child visiting my grandfather's family home in Akita, I remember the sight of sake bottles lined up across the table from breakfast onward. Now ninety, my grandfather can still hold his liquor remarkably well. My paternal grandparents, by contrast, were both born on the coast of Shimane Prefecture — my grandfather in a fishing village, my grandmother in a hot-spring town — in what was once Iwami Province. One would ordinarily expect people from such backgrounds to be heavy drinkers, yet I sense here an intriguing history of genetic mutation leading down to me: the movement of the bloodlines that made me who I am.

Iwami Province gained renown for its silver-bearing mountains, and from the Warring States period into the Edo period, war after war was fought over control of the Iwami Ginzan silver mine as one hegemon gave way to the next. For a long stretch of history, to command Iwami Ginzan was to command Japan. In the end, the Tokugawa house brought the mine under the direct control of the Edo shogunate, and throughout this process miners and laborers poured into Iwami Ginzan from across the country in search of work, creating a veritable melting pot unique in the Japan of its day and fueling immense prosperity. Along the coast of Iwami Province, moreover, abundant traces remain of independent trade with the Korean peninsula from ancient times, and judging from the deities enshrined at local shrines, the coast clearly flourished as a settlement for migrants from or by way of Korea. My paternal grandparents' homeland, in other words, was a true melting pot long before the emergence of "the Japanese" as a single unified people, and my reading is that a wide diversity of genes intermingled there.

My paternal grandfather died before I was born, so I never met him; according to my father, he could hold a fair amount of liquor, whereas my grandmother never drank a single drop. Another crucial piece of the puzzle is my maternal grandmother. She was born on a remote island in the Seto Inland Sea, a body of water whose islands had since antiquity lain along the main sea lane linking Kyushu with the ancient political heartlands of Nara, Osaka, and later Kyoto. Because of this geopolitical position, pirates made their home among these islands from early times, and by the Kofun period their presence already carried considerable weight. In myth, when Kamuyamato Iwarehiko — who would ascend the throne as the first emperor, Jimmu — traveled by this Seto Inland Sea route from Hyuga Province (present-day Miyazaki Prefecture) toward Yamato (southern Nara Prefecture), he was repeatedly set upon by pirates. Around the fourteenth century, this tradition of Seto Inland Sea piracy coalesced into the formidable Murakami naval confederacy, whose command of the seas at times threatened the central political authorities themselves. Traces of that history endure today: the technical heritage of those seafaring bands made the islands one of Japan's major shipbuilding centers around the time of the Second World War, and shipbuilding continues on certain islands even now. Given such a background, one might picture hard-drinking islanders, yet this grandmother, too, never touched a drop of alcohol. Naturally, on remote islands with histories as varied as piracy and maritime trade, all manner of peoples mingled over the centuries.

Viewed in the round, then, my complete lack of alcohol tolerance is a genetic mutation inherited from both of my grandmothers. Simply bringing ancient history, myth, folklore, and genetics together in a plural inquiry grounded in fieldwork is enough to uncover a fascinating history leading straight to oneself — and that is part of what makes Japan so compelling. Even so, following this thread raises a larger question: why does the custom of offering sake to the gods run so deep in Japan? When nearly half the population lacks a strong genetic tolerance for alcohol — when the country is, in genetic terms, evenly split — why did a culture of drink spread across the entire archipelago?

What my cumulative fieldwork and research have led me to think is that beneath the surface of history lay a far more plural world of sacred drink, one whose primary ingredient was not rice, as we automatically assume whenever we hear the word "sake" today. Most contemporary Japanese alcoholic beverages are made from rice, sweet potatoes, or barley, with rice predominant, and the sake offered to the gods is almost without exception brewed from rice. Yet drawing on my own investigations into myth, ancient oral traditions, and folklore, I do not believe for a moment that rice culture once blanketed the entire Japanese archipelago, and I view the custom of offering rice-brewed sake at shrines as the product of the uniform standardization of Shrine Shinto from the Meiji era onward. That false picture, in my view, is the result of deliberate manipulation by Kunio Yanagita, the founding figure of Japanese folklore studies. From the time he launched the discipline before the war, Yanagita traveled throughout the country conducting fieldwork, and he must have seen again and again a Japan very different from today's — a Japan in which rice and wet-rice farming were not the axis of daily life. Yet whichever of Yanagita's writings one turns to, a fixed equation — "Japan = rice cultivation" — sits firmly in his mind, and he conducts his surveys across the country as if checking his findings against a predetermined answer. Put simply, his approach was arbitrary and did not reflect reality. Worse still, Yanagita held to the self-serving prejudice that regions unable to grow rice were inferior and stood outside the main line of Japanese history beginning with the emperors. In doing so, he cast aside the sophisticated Jomon-derived cultures that had lived by swidden farming centered on rich traditions of millets and tubers, lending his discipline of folklore studies to the construction of a monolithic image of the nation. Because Kunio Yanagita stood as the founder of the field, his work was cited on a vast scale down to the present day, and before anyone realized it, a picture of Japan built on his arbitrary values had hardened into common sense.

As a result, even regions that once knew no paddy fields — lands unsuited to wet-rice farming in the first place — are now almost universally covered in rice paddies, creating a landscape that is in fact an anomaly in the long sweep of Japanese history, while the swidden agriculture that once flourished across wide areas has withered to the point where only a handful of farming households practice it in the entire country. As the recent turmoil surrounding rice in Japan makes plain, this single-minded worldview of rice and paddy cultivation was fabricated under the wartime regime of the Second World War, with origins reaching back to Meiji. Simply put, rice-cultivation faith tied to the origins of the imperial house — the equation "emperor worship = Japan = rice cultivation" — was indispensable for inventing "the Japanese" as a single, unified national people. What if, in the course of that era, a brewing culture that had originally been richly plural was compressed into the uniform shape it wears today? That is the standpoint from which I am thinking, and following this insight may well open a path toward uncovering the ancient strata of Japan. Before an arbitrary image of the nation-state was erected in the Meiji era, I suspect, the offerings of drink presented to the gods belonged to a plural world of worship made from ingredients far beyond rice alone.

We live at a moment when not only planetary climate change, but every premise of modernity demands to be reexamined by each of us in turn. For Japan, that means a thoroughgoing reassessment of its history from Meiji onward. If we cannot make far-reaching decisions now, a future is bearing down on us in which neither the state nor the individual will be able to stand. In Japan, one cannot change the state or society as a whole; precisely for that reason, individuals have no choice but to keep changing on their own, ahead of the tide of the age. And everything will depend on what kind of ideal future each person is able to envision.
