Music was a prayer before it was a pastime

Among the many traditions of Japanese music, one reaches back to a distant past long before foreign influences reached the archipelago: the music known as kogaku (古楽).

What comes to mind at the mention of "traditional Japanese music"? Most people picture instruments such as the koto, the shamisen, or the shakuhachi; gagaku (雅楽), the court music performed in Shinto rites; or theatrical arts such as Noh and Kabuki.

Yet most of what passes for traditional Japanese music today took its shape after being transformed by foreign cultures at various points in history. The older, indigenous music that existed before those outside currents arrived is therefore set apart under the name kogaku, or ancient music. Even so, centuries of historical change have blurred its outlines, making kogaku a complex tradition that resists any simple definition.

Any definition of kogaku turns on the political and cultural world of the eighth century. The decisive moment came in 701, when the Taiho Code — modeled on the legal system of Tang China under Empress Jito — was promulgated in what is now Nara Prefecture, establishing an official bureau of music known as the Gagakuryo (雅楽寮).

The creation of the Gagakuryo owed much to continental music brought to Japan from China and beyond through Baekje and Silla, the kingdoms on the Korean peninsula with which ancient Japan had long maintained close ties.

Against this backdrop, music that had arisen in Japan before the founding of the Gagakuryo came to be distinguished as kogaku. The term gagaku, however, carries its own complications. Although gagaku originally referred to foreign court music in Japan — specifically togaku (唐楽) from Tang China and sankangaku (三韓楽) from the three Korean kingdoms — later generations broadened the word to encompass Japan's own ancient music as well.

Japanese kogaku falls broadly into four traditions: kagura-uta (神楽歌), saibara (催馬楽), kume-uta (久米歌), and azuma-asobi (東遊). What sets them apart is that none was ever purely instrumental; all four were built around song and spoken recitation. Music in ancient Japan was inseparable from the human voice and the need for words.

By contrast, the gagaku brought over from China and Korea in that era was foreign court music performed entirely on instruments, without singing. Even today, this kind of instrumental court music is what fills the air at New Year's shrines and local festivals, so that most Japanese take it to be their own indigenous tradition — when in truth its roots lie overseas.

Japanese sokyoku (箏曲), played on instruments such as the koto and shamisen, is likewise centered on song, though a handful of purely instrumental pieces do exist.

More striking still, the purely instrumental "traditional Japanese music" that both Japanese and foreign listeners now picture is a surprisingly recent invention, taking shape only from the Meiji period onward after Western classical music began pouring into the country.

Seen in this light, the true heart of kogaku is koyo (古謡) — ancient song — born from singing and recitation. Indeed, ancient Japan had a class of hereditary reciters known as kataribe (語部), who occupied a position of great importance at court and in ritual life. Their task was to preserve and hand down ancient lore by speaking it aloud.

What melodies or rhythms Japanese kogaku actually possessed before continental music gave rise to gagaku is now almost impossible to know. More than thirteen hundred years stand between that world and our own.

Still, faint traces of kogaku survive in the oldest extant books in Japan: the Kojiki (compiled in 712) and the Nihon Shoki (compiled in 720). As for the instruments on which kogaku was played, scholars have pieced together their nature from the few treasures preserved in the imperial collections and from artifacts unearthed by archaeologists.

Both the Kojiki and the Nihon Shoki were, of course, compiled in the eighth century, and the sensibilities of that newer age unmistakably color their pages. Even so, these chronicles were not spun out of fantasy; they were assembled by gathering ancient traditions that had been passed down orally across the provinces long before. The compilation of the Kojiki was in fact a state enterprise set in motion by Emperor Tenmu (r. 673–686) himself.

The oldest record of kogaku appears in one of the central myths of the Kojiki. When Amaterasu — revered today as the ancestral deity of the imperial house — shut herself inside a rock cave, the entire world was plunged into darkness. Famine and pestilence broke out, throwing the land into chaos, until the remaining gods devised a plan to draw Amaterasu back out and gathered to perform a sacred rite.

That rite before the cave is the very wellspring of kagura-uta, one of the four traditions of kogaku. Even now, the kagura (神楽) performed in ceremonies at the imperial court is regarded as the most solemn of rituals for welcoming the descent of a deity; following ancient Shinto observance, dancers offer their movements to the accompaniment of sacred music. This is not entertainment, but a grave Shinto rite — and the kagura-uta chanted during it preserve echoes of a deep antiquity.

What, then, was Japanese music really like before foreign influences arrived? To follow that question is to come face to face with a belief that lay at the very heart of ancient Japanese culture: kotodama (言霊), the vital spirit dwelling within words.

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 “Music was a prayer before it was a pastime”, first written on 14 February 2025. What is ancient Japanese music, before foreign influence? Before it was entertainment, music was a rite, Takahiro Mitsui observes: sound carried the living spirit of words, kotodama.

In “Music was a prayer before it was a pastime”, Takahiro Mitsui writes about kogaku, gagaku, kagura and Kojiki, with Empress Jito and Emperor Tenmu. The places in the essay are Nara and Baekje.

Takahiro Mitsui's thesis: kogaku, the music older than continental influence, was built around song and spoken recitation; none of its four traditions, kagura-uta, saibara, kume-uta and azuma-asobi, was purely instrumental, and music in ancient Japan was inseparable from the human voice and the need for words (SJ 049).

Takahiro Mitsui's thesis: the oldest record of kogaku appears in the Kojiki, in the rite that drew Amaterasu out of the rock cave, the wellspring of kagura-uta; to ask what Japanese music was before foreign influence is to meet kotodama, the vital spirit dwelling within words (SJ 049).

Takahiro Mitsui: "Since ancient times in Japan, words have been held to carry spiritual power as kotodama (言霊). Read in contemporary terms, words are the most effective technology we have for stepping out of a reality fabricated by others and living in an otherwise impossible reality of our own." (Silence is built within, 2025-11-27)

Takahiro Mitsui's thesis on this question: Kotodama: Receiving the World by Its Sound — Why did Japan accept Buddhism by its sound? Takahiro Mitsui, a Japanese philosopher born in 1991 who does fieldwork outside academia, answers: ancient Japan read the sutras aloud and judged them by the spirituality dwelling in their sound.

Takahiro Mitsui's thesis on this question: Kagura: From Harvest Offering to Stage — Izumo kagura vs Iwami kagura: what is the difference? Takahiro Mitsui's answer: Izumo keeps a stately six-beat rhythm, Iwami a thunderous eight-beat one; once an all-night harvest offering, kagura now lives partly as an hour for tourists.

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: “Have any of us ever truly looked at where we come from?” (Project 2049 Vol.0, https://project-2049.takahiromitsui.com/vol-0 )
