A name carries power

The Japanese of today no longer grasp how important a name is, but this is a phenomenon of the last thirty years or so, and in the whole of Japanese history it is a very new attitude. Even now, though, the custom of "giving one's name" on a first meeting and of calling the other by a job title is deeply rooted in society. Through a long history, names were once held sacred, and through names a world like a fantasy, swirling with political intrigue, unfolded. It is a truly interesting custom, and the key to understanding it is "avoiding the real name" (jitsumei kihi) and "the double name." From this view, this time I will take the first step into that strange world.

I always feel strongly, as I travel the whole country to explore ancient Japan, that to make a trip to Japan the deepest experience possible, an understanding of names is indispensable. By names I mean not only the names of Japanese people but the names of lands, of shrines, and of gods. Japanese is a hard language for readers, but I would be glad if, through Shitsurae, you could deepen your understanding a little and spend days in Japan that deeply affect your future lives. Tourists today pay no attention at all to Japanese names, but merely understanding this opens endless possibility.

Go far back in time and open Japanese myth, and the names of the gods are very long and of a distinctive sound, and their meaning and sound were believed to hold special power. This is closely tied to the fact that Japan, unlike China, originally did not need a culture of writing, and so a faith that sound itself is the god lasted a very long time. Its developed form is what many readers are curious about, the mystery told in the Shinto context as "kotodama (言霊)," or "otodama," the spirit of words and of sound. Since I basically research ages without texts, I have countless times read hidden history from the names of gods and lands, and, interestingly, through it one can glimpse the reality of antiquity. It may sound absurd, but it is fact.

The name of the first god to appear at the opening of the Kojiki, Amenominakanushi (天之御中主神), for example, generally carries the meaning "the god who presides over the center of heaven," and the name itself expresses divinity. The Edo-period Kokugaku scholar Norinaga Motoori (1730–1801) made a great contribution to the interpretation of this god's name. But since the names of gods, though they belong to our ancestors, are deeply bound up with the faith of Japanese from an unimaginably distant age, nothing that can be called a correct interpretation exists. In fact the 天 of "Amenominakanushi" was imported and adopted in Japan as a term for the heavenly realm in the Chinese sense, but this "ama" appears, in old texts alone, in countless forms: 天, 阿麻, 海部, 菴, 甘, and others.

This is because, after Chinese characters came in, Japanese sounds had to be reduced to characters, and so a character close to an appropriate concept was assigned. Seen from Japanese, though, "ama" tends to be used not for the heavenly realm of the Chinese immortals' worldview but, as befits Japan, ringed by sea, for a concept tied to the "sea." In Japan, people who live on the coast and fish are still called "ama (海人)," and women divers "ama (海女)," and among place names, many that bear "ama" remain, Amami Oshima first among them. There were also ancient clans that stood for "ama," and as the "Amabe clan" (海部氏), descendants of the Tango Amabe clan on the coast of the Tango Peninsula in northern Kyoto Prefecture still hold, by inheritance, the priesthood of Kono Shrine. Several other place names tied to the Amabe also remained until regions were merged and abolished around the twentieth to twenty-first century, and in Oita Prefecture, for example, the name Amabe District plainly survived.

Frankly, the ancient history of this sound "ama" alone is so deep that many people could write books on it, and it cannot be pinned down, but in this way Japanese sounds hold immensely deep meaning asleep in them. So even if I tried to tell readers the myths of the Kojiki, "Amenominakanushi" alone would need a vast study, so I carefully avoid this point. Above I briefly gave the meaning "the god who presides over the center of heaven," but with that general understanding one cannot touch the divine power of "Amenominakanushi" in the least, and it remains a state that cannot be discussed in any language but Japanese. Because this character of sound faith shows to the fullest in the names of gods, there may be no being harder to read than the gods of Japan. The nature of Japanese myth, to begin with, shows that the very act of naming was a sacred act of creation, and that the ancient Japanese held the sense that spiritual power dwells in a name. This leads to the thought of "kotodama," and since ancient times in Japan it has been believed that spiritual power dwells in words and shows when they are spoken. Even Kukai of Shingon, who at a glance seems unrelated, set up a theory interpreting kotodama in the esoteric way from the view of "shingon, the true meaning of words." So speaking the name of a god was itself a precious prayer, and people's names too were handled with care. I think you know better than I that the same was true not only in Japan but everywhere in the ancient world.

Against this background of worshiping the ancient sounds of Japan (that is, the gods), a custom of "shunning" the public calling of another's real name arose in ancient Japanese society, and it had a great effect on later history. Especially in the Asuka period (538–710) and the Nara period (710–794), when the political system strengthened its centralizing tendency, it is notable that this custom of avoiding the real name was institutionalized to raise the authority of the rulers. The Kojiki, my theme of research, also had as one aim to systematize the grounds for legitimizing each clan's name under the emperor and, through names, to hold down the clans' authority. So, to the native Japanese custom that already existed, the system of avoiding names called "hikki" (避諱) was taken as a model from Tang China, which held enormous influence, and finally put in order on the scale of the state.

As a typical case, the Taiho Code, set in 701 under Emperor Monmu, the forty-second, clearly provides "avoid the names from the imperial ancestors on," that is, not to use the "imina" (諱, the name to be shunned) of emperors and imperial family members in daily life. Then in 757 an imperial decree was issued avoiding the names of the emperor and empress, and in the following year, to avoid the character 史 used in the name of a son of Fujiwara no Kamatari, one of the powers who controlled the court, six clans that bore that character in their surnames were made to change their surnames, as recorded in the Shoku Nihongi. In this way it came to be shunned to say the names of emperors and noble people directly, and under the ritsuryo state it became an open taboo.

I personally think such a custom existed within tribes from ancient times, but what actually strengthened it was the noble society that rose in the Nara period and the Heian period (794–1185). In this age the real name was thought to be extremely private and sacred to the person, and was hardly ever spoken in daily life. So when others called a person, a different name called a "tsusho" (通称), a common name, came to be used instead. The real name, also called the "imina," was set as something only those in special positions, such as parents or lords, could use in limited ways on formal occasions, and for anyone else to say it was thought disrespectful. In fact, in the texts and diaries of the Heian period, there is no scene of nobles calling each other by real names, and instead names based on office or the name of their residence are used often.

Among noble men, for example, names taken from the location of their own house or their office were usually used, and Minamoto no Masanobu (920–993), a Heian noble, was called "Tsuchimikado Sadaijin" from his residence on Tsuchimikado Avenue in Kyoto and his post of Minister of the Left. From the middle Heian period on, women too came to be called by the office of their father or husband. The most famous, Murasaki Shikibu, the author of the Tale of Genji, was called Murasaki Shikibu not by her real name but from her father's post of Shikibu no Jo, so to this day her real name is uncertain, with several theories. And Izumi Shikibu, the author of the Izumi Shikibu Diary, also known as an excellent poet, was likewise called so not by her real name but from her husband's post of Izumi no Kami, and her real name too is unknown. In this way the nobles used a "double name," hid their real names, and called each other by common names. Why, then, did these nobles cling to a custom of avoiding the real name so far?

At its undercurrent lies, from the view of kotodama faith, a belief that a name is deeply bound to a person's character and soul. So a name was thought not a mere mark to tell individuals apart but to express that person's soul. For one's true name, also called "mana," to be known or called by another carried the fear that the other would hold one's soul, and people in fact held considerable fear and anxiety over it. In fact, in ancient times and also in the Middle Ages, there were many cases where a person was destroyed by the grudge of an enemy through his real name being known, and secret arts of cursing and torturing by name even flourished. We can learn from the Tale of Genji that the nobler a person, the more often he drew others' jealousy and anger, and nobles kept their real names secret to protect themselves and avoid calamity, and also used it to show the greatest respect to the other.

The naming of small children too was attended by a solemn rite, and there was a custom of calling a child by a provisional name until the formal name was given at the naming ceremony on the seventh day after birth, and not only among nobles but later among warriors too, it grew complex, using several names according to one's growth and rank. When a small child fell gravely ill, the cause of the illness was strongly thought to be the name, so there are cases in which the name was changed to ward off misfortune, which shows that it was believed that a name holds a spiritual power that can even decide a person's fate. The Japanese still believe this strongly, and many people believe that naming a child decides the child's future. That is why each Japanese name holds a parent's deep feeling and wish.

And this was so not only for the living but for the dead. The real name of the dead was also a strong object of shunning, and in particular, to emperors and nobles another name called "okurina" (諡) was given after death. It was an honorific that replaced the name in life, and by offering it, the soul of the dead was comforted, and it also served so that those left behind need not call the real name directly. As for emperors, the Japanese of today sometimes call them by the era name as it is, as "Emperor Heisei" or "Emperor Reiwa," but this is a new custom since Meiji, a modern phenomenon in which era name and "shigo" (諡号, which means okurina) are used as one. So the names commonly known for the emperors Jimmu, Tenmu, Kanmu, and the rest are all shigo, not real names. The emperors of that day were not called by such names.

In this way, names have been treated as special in Japan since antiquity, and its influence can be seen even now. Even in business it is out of the question to call a superior or an elder by the given name, and the habit of calling by family name or title shows respect for the name itself and a psychological distance. Though we seldom notice it, the historical culture of "respecting and being careful with names" can be said to be still handed down, unbroken, in our Japanese society.

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 “A name carries power”, first written on 11 May 2025. Why do names carry power? Takahiro Mitsui observes a name is a source of power, and avoiding the true names of elders keeps respect and distance alive.

In “A name carries power”, Takahiro Mitsui writes about names, kotodama, taboo and Heian aristocracy, with Motoori Norinaga, Murasaki Shikibu and Izumi Shikibu. The places in the essay are Tango and Oita.

Takahiro Mitsui's thesis: the name of the first god of the Kojiki, Amenominakanushi, admits no correct interpretation, because the names of gods are deeply bound up with the faith of Japanese from an unimaginably distant age; 'ama' appears in old texts in forms such as 天, 阿麻 and 海部, and tends to be tied to the sea (SJ 112).

Takahiro Mitsui's thesis (SJ 112, published 2025-05-11): in ancient and Heian Japan the sacredness of names shaped the taboo on real names (jitsumei kihi), dual naming and posthumous titles.

Takahiro Mitsui's thesis: Murasaki Shikibu was called by her father's post of Shikibu no Jo and not by her real name, so her real name is uncertain to this day; nobles used a double name and hid their real names because a name was thought to be bound to a person's soul (SJ 112).

Takahiro Mitsui: "Who gives a name? … Thinking about this question should not be pointless for us, living as we do in an age that has handed out so many names that everything has become excessive." (A name is born in a place, 2026-08-05)

Takahiro Mitsui's thesis on this question: Musuhi: A New God for an Alliance of Peoples — What is musuhi, and how were Japanese myths born? Takahiro Mitsui's answer: musuhi, not musubi, is hi bound together so all things arise in non-separation; merging peoples did not raise one tribe's god, they created a new god under a common ritual.

Takahiro Mitsui's thesis on this question: Divine Names Are Born in Places — Where do the names of the Japanese gods come from? Takahiro Mitsui's answer: a name arises in a place, so there are as many names as places, each true. Names shift along the Kuroshio; the sound before kanji tells which people carried it.

Takahiro Mitsui's thesis on this question: A Name Carries Power: Why the Japanese Avoided the Real Name — Why do names carry so much power in Japan? Takahiro Mitsui, a Japanese philosopher born in 1991, traces the old custom of avoiding the real name, the double name and the fear of a name held by an enemy, still alive in how Japanese address each other.

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 )
