Escaping the dopamine world

"People are each different." In a modern world where everything is being individualized, each of us is pressed to set aside, deliberately, time and space to be with ourselves, and to take this up with a medium- and long-term plan. Introspection has become one of the essential skills for surviving a harsh age. But the world is not made of pretty phrases, and it is also true that a certain number of people are in trouble if others turn toward introspection. "Awakening" may be too grand a word. Still, once you are taken inside the structure of "dopamine addiction" that is the basis of marketing in the modern world, you cannot easily get out, and you are stripped of time (and money), the most important resource any individual has. This is now a serious problem facing all of humankind.

For people who are already taken into the structure of the modern world, who do not know its "outside" or do not even try to know it, this dopamine world is simply reality, however much they might wish to turn to introspection. As this polarization advances to its extreme, one side will be those who redesign their lives and possibilities on the basis of introspection and move into the future at an accelerating pace. The other side will be those whose minds and bodies are ruled by an excess of dopamine, and who end their lives without ever once taking themselves back. Obviously the point that joins the two layers becomes important then, and under names that will change, new philosophies and religions of one kind or another will rise one after another.

But introspection, as everyone knows, is no easy matter. It is not a momentary pleasure (a trigger of dopamine). It continues over a whole life, changing as it goes. However famous a monk or a Shinto priest may be in history, we should not forget that each of them became a pioneer by being buffeted by the currents of his time and still not giving up introspection, designing the future from within himself. In our age especially, with brain science so advanced, it is extremely hard for an individual to escape a dopamine world built by abusing it. Seen another way, the many events now happening in the world have the effect of amplifying dopamine. They can trigger it even in people who have no direct connection to the events themselves, and the resources taken from them (time, money) can then be collected in one place. One could call it a groundbreaking age for those who build such a system.

That is why people urge, even about small things in daily life, that we quit social media or keep our distance from it. The strange thing about social media is that people like me, who do not use Instagram, X or TikTok and have no accounts, are not even allowed to access them. Yet most people can no longer live without social media. Anyone who has traveled in Japan knows that in Japan, which stands at the very front of the dopamine world, it is extremely hard to find good food. Residents of the dopamine world presumably enjoy Japan's food without noticing, as the country that boasts the world's largest "number" of restaurants. But in reality the quality of Japanese food has very serious problems, and what it amounts to is a "flood of the coarse."

If you look in Japan for delicious sweets that are gluten-free and free of dairy, white sugar and additives, you cannot buy them in cities. Usually an individual living in the regions runs a small shop, or has no shop and sells from a mobile stall, so days and places of business change often. When I travel I go to such places too, and what I sometimes find troublesome is that information on their business can generally be found only through Instagram. It seems to me a strange structure. Even when you want to maintain or improve your health, you somehow have to step into the dopamine world of Instagram, as if it were an "initiation ritual," and the very people who work to promote health have not themselves escaped the dopamine world. After about five years of going around, frankly, I feel that this is the reality of Japan's wretched organic culture.

In an age when 99 percent of humankind is dopamine-dependent to one degree or another, the first priority is not "introspection." Before that, it is to review what we eat and restore health over time. Until we regain the health of mind and body, no matter how many kinds of meditation we try, we are not ready to remove the noise, so there is no way we can reach real introspection. The bodies of modern people are soaked in poison, beginning with pesticides, additives and chemical compounds, so we are asked to restore the body's natural ability to expel them and then, above all in what we eat but in all of life, to make an effort not to take in poison in large amounts. In a sense this is the shojin (精進), the devoted discipline, of modern people. In every age, such discipline runs against the mood of the times and defies it, and I cannot help feeling that continuing it is the road to introspection. Whether one is Japanese or not does not matter here. It is rather a problem on the scale of humankind.

Seen from another angle, the structure of the modern dopamine world feels very much like the system of Disneyland. It has been about ten years since young people in Japan became addicted to Disneyland. That is not simple escape from reality. For most young people it is a world that fits extremely well with the dopamine world, which is their world.

My own question is this. I think that modern Japanese culture also moves inside the structure of this dopamine world. There is, to begin with, no such thing as "Japanese culture." What existed was countless cultures nurtured plurally, each in its own place, and in Shitsurae I keep making that claim. Takaaki Yoshimoto, the greatest thinker of postwar Japan, presented this structure as "self-illusion," "pair illusion" and "communal illusion," but he did not get as far as a theory. The one who took over the hard task of turning the concepts he presented into theory is the philosopher I respect most, Tetsuji Yamamoto. I always hold that there is no understanding of Japan without understanding him. Even now, approaching eighty, Yamamoto sharpens his thinking every day to fulfill his mission and keeps publishing one ambitious work after another. Through him Yoshimoto's The Theory of Communal Illusion is being given its theoretical form, and when we reach an age in which people appear who use it, the "Japanese culture" as it is now understood will collapse and an essential Japanese culture will become manifest. This is a realm I too am always thinking about and working in, and it will still take years. But the essential Japanese culture has already started to move.

From this point of view, there may never have been an age when it mattered more to look inward at yourself, rather than being led astray by the dopamine world outside and wasting your life. The strength of facing yourself and designing your life (your possibilities) from within is entirely different from the structure of a world that has been systematized to trigger dopamine in great numbers at once. Put another way, it is an individual matter: how to live with a dopamine constitution that differs from person to person. As with Japanese culture, even in a dopamine world, dopamine metabolism differs from one person to the next. It is less that things are individualized than that the basic rule of the dopamine world is to keep people from noticing that each is different, and it is possible to escape from there. The builders of the system can still construct this dopamine world only within a single, uniform framework. They have not yet completed the recovery of people into an individualized dopamine world. That completion, though, is probably only a matter of time. To deepen our understanding thoroughly before it comes will be the most important factor for surviving the future, even more than it is now.

So we want to understand our own dopamine metabolism. By understanding our genes and knowing our dopamine metabolism well, it becomes entirely possible to leave the dopamine world or keep our distance from it. And as I said, escaping this dopamine world is the same as escaping Japan, the Japanese and Japanese culture, and it becomes the basic ground from which to see Japan, the Japanese and Japanese culture in the true sense. This is the starting point, and the real wonder of Japanese culture lies here, boundless and without limit.

But seen the other way, the builders of the dopamine world, once they obtain the genetic information of the people they have taken in, could update the system so that those people can never escape again. That is why, before they establish such a system, we need to prepare at the individual level: understand our own genes and metabolism, and deepen introspection thoroughly in line with them. The futures of those who prepare and those who do not will differ not at the level of the polarization now spoken of, but at a level that touches danger to life itself. And if the dopamine world is updated before individuals have prepared, the near future will arrive in which it is impossible to leave it.

This is probably hard to follow, so let us think about matcha, commonly regarded as a symbol of Japanese culture. Matcha is now consumed around the world. When I went to Bangkok this month, products with matcha in their names were flooding every corner, and travelers who come to Japan consume so much of it that one could call them matcha addicts. (It is not even known that the Japanese themselves do not drink that much matcha.) This past month my younger brother, who lives in Europe, has been back in Japan with his girlfriend, and she, from Europe, drinks matcha daily and has become addicted too.

Matcha is now known around the world as a leading symbol of Japanese culture, but have you ever thought about what lies behind that? What I want to ask is whether matcha was really so closely tied to the Japanese that one can call it a Japanese culture embracing all the Japanese.

I have so far studied it mainly from the historical angle, and I believe it is a fact that matcha could never have been consumed across the whole of Japan through history. It was a taste of a very limited few. So I suspect that for most Japanese matcha in fact does not contribute much to health, and may often do harm. That deserves attention given that most Japanese historically had no habit of drinking matcha. What I want to look at here is EGCG (epigallocatechin gallate), found in large amounts in green tea, the broader category above matcha. In recent years EGCG has drawn attention from many angles, including antiviral action. But is green tea, with far more EGCG than imported black tea or oolong, really good for the Japanese (and for foreigners), within Japan's historical tea culture (one could call it a green tea culture)? Such claims are now prominent, but there is a large pitfall here.

What I especially want to take up is COMT (catechol-O-methyltransferase). The neurotransmitters dopamine, norepinephrine (noradrenaline) and epinephrine (adrenaline) are called catecholamines. Dopamine, synthesized from phenylalanine in food, goes in three main directions: it "works at the receptors," it is "taken up again," or it is "broken down." There are several routes by which dopamine is broken down, and the most important is the COMT route. It is the metabolic route that breaks down synthesized dopamine, and flushes it out in urine bit by bit, so that it does not become excessive. In outline it runs like this.

Dopamine

↓ COMT + SAMe + Mg

3-MT (3-methoxytyramine)

↓ MSOB + B2 (FAD)

HVA (homovanillic acid) → excreted in urine

What matters in breaking dopamine down to 3-MT is COMT, and whether the gene has a variant is one indicator. The one that gets the most emphasis is a polymorphism called Val158Met (rs4680). With the Val/Val type (GG), COMT is highly active and dopamine breaks down quickly, so dopamine in the prefrontal cortex tends to be low. With the Met/Met type (AA), COMT is less active and dopamine breaks down slowly, so dopamine in the prefrontal cortex tends to be high. The GG type is described as resistant to stress, resistant to pain, somewhat poor at sustaining concentration, and low in working memory. The AA type is described as strong in cognition and memory, strong in working memory, weak under stress, sensitive to pain and prone to anxiety.

COMT activity types

・High activity (HEA)

・Medium activity (MEA)

・Low activity (LEA)

Looking at how these haplotypes are distributed, in the distribution studied so far in Japan, HEA is about 33 percent, MEA about 24 percent and LEA about 39 percent, so the share of low-activity COMT (that is, slow dopamine breakdown) is relatively high (it varies greatly by individual and by place). Low-activity COMT tends to keep dopamine in the prefrontal cortex high. Lifestyle and other genetic factors must be taken into account, but it is generally thought to bring fatigue, headache, changes in sensitivity to caffeine and difficulty relaxing (a dominant sympathetic nervous system) as its main features.

For someone with low-activity COMT, the lifestyle point is to avoid anything that inhibits COMT activity. Among the foods where restriction is recommended is one that touches the Japanese directly: EGCG, a component of green tea, which is believed to be historically rooted in the Japanese. And EGCG is the most powerful COMT inhibitor of all. Here we begin to see the truth that there is no health method that works for everyone. At this stage, then, I take "the Japanese equals tea culture (green tea culture)" to be a typical case of a quite mistaken perception that has been generalized, and I think that by sharpening our reconsideration of this received idea we may find a thread that leads to the collapse of Japanese culture as a whole.

For this reason, people with low-activity COMT are advised to limit green tea to two or three cups a day, while those without it are said to be fine with five or six. But that is the general view, and I feel it no longer holds today. The green tea that today's tourists can reach is of extremely poor quality. Those with high-activity COMT may be fine to a degree, but those with low-activity COMT need to be quite careful. If a tourist with low-activity COMT comes to Japan and drinks tea as he pleases every day, the excess EGCG will inhibit COMT intensely, and there is a high risk that dopamine metabolism will break down and he will fall ill.

This applies to everyone, not only to COMT. Bottled green tea sold at convenience stores is developed in the first place to heighten the EGCG effect, so people with low-activity COMT had better avoid it. Green tea in the past and green tea today are completely different things. It may surprise you, but of the roughly 56,700 convenience stores said to be in Japan, I go into one about once a year, and I never buy their goods (only to use the ATM or buy water). Personally, then, I think people with low-activity COMT should basically not take green tea that is easy to get. I think it is far better to spend that effort looking for good tea and to drink a cup or so of a fine one you have found, and I believe that a journey in search of it is truly a wonderful Japanese experience. EGCG is not the only one, of course. Chlorogenic acid in coffee, dark chocolate of 70 percent cacao or more (cacao polyphenols) and red wine are also well-known COMT inhibitors.

These conclusions are drawn individually from very complex and varied factors. Even so, taken broadly, for people with low-activity COMT green tea (EGCG) is not something to be recommended as a symbol of Japanese culture. It is a food that calls for care, and it raises serious doubt over whether "the Japanese drank green tea" was ever really a historical habit. What is commonly called tea culture is in substance far too plural. The beginning of tea as culture is said to lie in Chinese culture brought from Tang China by the Zen monk Eisai and others, a current that began basically in Kyushu. I do think, though, that tea plants themselves grew wild in Japan before that, setting aside whether anyone cultivated them. In Kyushu I have confirmed for myself that tea plants grew wild after the burning of fields in the slash-and-burn farming that continued from the Jomon period.

Later, as the age passed from aristocrats to warriors and Zen, which suited the philosophy of the warrior, rose, tea culture spread to many regions. The main cultural centers were in western Japan, from Sakai in Osaka to Kyoto. Production spread widely, but its northern limit lies in Murakami City, Niigata Prefecture, which I visited in late summer. Seen across Japan as a whole, tea production and tea culture were extremely limited, and since cultivation, processing and ways of drinking differed from place to place, the content must have varied considerably too.

My greatest research theme is that Japan originally had plural tribal groups that differed from place to place. Taking that into account, genetic relationships themselves differ greatly by place, and I imagine that tea culture differed too, according to the place (the genes of the people who lived there). Without knowing anything about COMT or other genes, our ancestors probably used a refined wisdom to drink the tea that suited them best. Conversely, the tea served to them when they visited elsewhere may well have been tea that did not suit them (their genes).

For the Japanese, in fact, this lineage is tied not to tea but to "the taste of miso soup." Miso soup too is highly plural, and quite a few people cannot eat miso soup unless it tastes like the one their mother made. The taste of miso soup was handed down from mother to child through the generations. It is a fascinating case of a "taste of miso soup" suited, genetically, to a person's lineage. That is why even now many people who have left for the city relax when they go home and eat their mother's miso soup. I think this is quite instructive for any inquiry into tea culture.

Today I have been dreaming about Japanese culture as seen through genes, and what I am thinking is this question: what will the near-future Japanese culture be, as experienced by people who have escaped the dopamine world? Perhaps there is a hint here for the next future, a possibility. For me too, as I am beginning to leave the dopamine world, it feels like a problem I have to keep thinking through. When we leave the dopamine world of the simple equation "Japanese culture equals tea," an "individualized Japanese culture" appears for the first time. Once we reach that point, a future may come in which an essential experience beyond language becomes possible. It is the world of spiritual experience, the last world in which those who have kept on with introspection gather.

The experience of Japan you have as a traveler may be nothing more than satisfaction handed to you by a dopamine world in which everything is managed and designed, like Disneyland. Japan is one of the places where the workings of the dopamine world show most densely. If you are interested, look at those workings objectively, from the standpoint of someone who has left the dopamine world.
