質実剛健 shitsujitsu gōken Plain, Honest, Strong
質実剛健 (shitsujitsu gōken) means plain and earnest, strong and sturdy. It is a Japanese compound of two old words, and the oldest print read for this history is of 1893. This study follows it through 徳富蘇峰's essays and the schools' motto to the English dictionaries that called it manliness.
Abstract
質実剛健, read shitsujitsu gōken, means without ornament and earnest, strong and sturdy, in the definitions of the デジタル大辞泉 and the 日本国語大辞典, whose earliest example is a sentence of 徳富蘇峰's of 1913 [1]. It is a Japanese compound of two old words, 剛健, the strength the Book of Changes gives to Heaven, and 質実, plain substance, and the four characters together were not found in the Chinese canon or the Chinese classics by any instrument searched for this history [2][3][4]. In the oldest print read at the page for this history, of 1893, they are a gloss on the Mito scholar 藤田東湖's complaint that the city spoils the plain man from the country, and 蘇峰 told the same story from an essay his book dates to 1889 to the sentence of 1913, in which the four characters are the one advantage the Yamato race holds over the white races [5][6][7]. The schools and the education press had taken them up by 1909, and the imperial rescript of 1923 wrote them into the imperial text against what the cabinet called foreign currents of thought; in 1931 kendo and judo were made compulsory in their name, in 1939 they were in a rescript to students, and in 1941 they were the ninth precept of the army's field code [8][9][10][11][12]. Schools keep them as a motto today; the English dictionaries kept one half, fortitude and vigour and manliness in 1942, frugal and courageous in Nelson's; and my reading, signed below, is that the four characters are a discipline one takes for oneself, and that they have most often been turned on someone else [13][14].
Overview
The sense. The デジタル大辞泉 at kotobank defines 質実剛健 as 飾り気がなく、まじめで、強くてたくましいこと, without ornament and earnest, strong and sturdy, and gives 「質実剛健の校風」, a school spirit of 質実剛健, as its example; the 精選版 日本国語大辞典 gives かざりけがなく、まじめで、強く、しっかりしていること, without ornament and earnest, strong and steady; both head the word しつじつ‐ごうけん [1]. The 四字熟語を知る辞典 gives the same definition and two examples, from 三島由紀夫's novel 仮面の告白 of 1949 and 有吉佐和子's 孟姜女考 of 1969 [1]. JMdict enters it as unaffected and sincere, with fortitude and vigor [15].
The words. 質実 is plain substance: the デジタル大辞泉 gives 飾りけがなく、まじめなこと。質素で誠実なこと, without ornament and earnest; frugal and sincere, with 「質実剛健」 as its example, and the 日本国語大辞典's earliest example is 伊藤仁斎's 童子問 of 1707 [3]. 剛健 is strength: the デジタル大辞泉 gives 男性的で、心身が強くたくましいこと, masculine, strong and sturdy in body and mind, and the 日本国語大辞典 たくましく男性的なこと, sturdy and masculine; its earliest Japanese example is the 空華集 of the Zen monk 義堂周信, 1359–68 or about then, and it names the Book of Changes behind the word [2]. The definitions of the four characters together do not use the word masculine; the definitions of 剛健 alone both do [1][2].
What follows. The historical record reads the four characters in the order of their lives: the two old words, the country man and the city, the race, the schools, the rescript of 1923, the years to 1945, and then the reading, today and the English. A reading is mine.
The historical record
Two old words
剛健 is the word the Book of Changes uses for Heaven. The commentary on the first hexagram, 乾, Heaven, says of it 剛健中正,純粹精也, firm and strong, central and correct, pure and refined [4]. The twenty-sixth hexagram, 大畜, pairs the word with another: 剛健篤實輝光,日新其德, firm and strong, sincere and solid, shining with light, renewing its virtue day by day, where firm and strong is Heaven below and sincere and solid is the mountain above [16]. 剛健篤實 is the nearest classical model for the shape of 質実剛健, two virtues with 剛健 as one of them; in the Japanese phrase 質實 takes the place of 篤實.
The four characters themselves were not found in the Chinese Buddhist canon at CBETA, in the full text of ctext.org's pre-Qin, Han and later collections, or at zh.wikisource, searched for this history; the control 剛健篤實 was found in all three [17]. In Japanese, 剛健 is in Zen writing of the fourteenth century and 質実 in 伊藤仁斎's 童子問 of 1707 [2][3]. In the National Diet Library's full text, searched oldest first for this history, the oldest dated rows of the four characters and of their sibling forms 剛健質實 and 質樸剛健 are of the 1890s, the middle of the Meiji era (1868–1912) [18].
The country man and the city
The oldest print of the four characters read at the page for this history is 活文字 of 1893, a book of essays by 鈴木天眼, a journalist, and 佃斗南 [5][19]. In the essay 精力の寓處, where vigor lives, the authors argue that the city is the source of softness and decay, and that a nation's vigor is nourished in the forests and the fields, and they quote 藤田東湖, the Mito scholar who died in the earthquake of 1855, on the men who come up to the capital: plain and fresh at first, with the air of mountain and lake, they end smooth and clever, and few keep what they were [5][20]. 東湖 closes [5]:
嗟乎山林江湖之士。欲全質於都會風塵之中。或亦難矣。
Alas, for a man of the mountains and the lakes, to wish to keep his plain substance whole amid the wind and dust of the city may well be hard. The authors gloss it:
盖し地方人士の都會に出てゝ、而して其質實剛健の氣象を全ふするの難きは、今昔の共に同しき所なりと雖とも
That a man from the provinces who comes up to the city finds it hard to keep his 質實剛健 temper whole is, no doubt, the same now as of old, although …; the sentence goes on to say that in the feudal age the city's habits reached the provinces less than they do now. 東湖's word is 質, plain substance, alone; the four characters are the gloss of 1893 [5]. 東湖's passage is from his essay on his own pen name, 東湖說, which his collected works print, and in which a guest asks whether a man of the city can still call himself East Lake [21]. The annotated edition of 1944 reads the line 質を都會風塵の中に全うせんと欲するも、或は亦難し [22].
徳富蘇峰 told the same story. His book 静思余録 of 1895 carries an essay, 田舎漢, the country man, which the book's own table of contents dates to the magazine 國民之友, number 52, June 1889; the magazine of 1889 was not read for this history [6][23]. The country man is the one a nation turns to in a crisis, and in the capital he goes soft: 木曾義仲 in Kyoto, the Ashikaga, and Rome [6]:
古へ羅馬の如き、其の始に於ては、其の人民、質樸剛健、鐵脚以て其の隣國を蹂躙したるにも係らず
Ancient Rome, whose people in the beginning were 質樸剛健 and trampled their neighbors with iron feet, ended with its Praetorian Guard turned, he writes, into something like princesses. 質樸剛健, with 樸 for 實, is the same pair of virtues. A boys' magazine of 1891 sets the Genji's hard men, who had valor out of 質樸剛健, against the Heike's courtiers who went to war with a flute at the waist [24][25].
In the next years the phrase is in children's compositions. A pupil's essay in a magazine of school compositions of July 1894 says that in a frivolous age of show, 浮華虛飾, a 質實剛健 manner is most needed [26]. In 1897 川崎三郎's biography 藤田東湖 says that 東湖 and his lord built the domain school and roused a 質實剛健 temper, so that Mito's ways were 質實にして剛健, plain and strong, honored integrity, and hardened into reverence for the emperor and expulsion of the barbarians [27]. The sentence is the biographer's, of 1897; 東湖 died in 1855, and nothing read for this history puts the four characters in his mouth [20].
The race
The country man's virtue was a national one from the first years. A magazine of September 1893 calls 剛健質實 the true character of the subjects of Great Japan, as history shows, and asks how it should end up behind the white man [28]. In 1913, in 時務一家言, 蘇峰 opens a section on the martial spirit, 尙武の氣象, with a saying of 藤田東湖's, better martial and foolish than lettered and soft, recalls that a writer he calls ヘヤソン had feared the day barbarians would take up the weapons of the civilized against them, and writes [7]:
我か大和民族にして、後進の一民族として、白皙人種と抗行し得る可き一は、唯た彼等よりも聊か質實剛健なりしを以て也。
If our Yamato race, a latecomer among peoples, can hold its own against the white races, it is only because it has been a little more 質實剛健 than they. If it loses that even for a day, he goes on, it has little left to rely on, and wealth has already begun to rot America [7]. This is the 日本国語大辞典's earliest example [1]. ヘヤソン is, by my identification from the context and not by 蘇峰's naming, Charles H. Pearson, the author of National Life and Character: A Forecast (1893) [29].
The schools
By the turn of the century the phrase belonged to the schools. 蘇峰's memorial of 井上毅, minister of education from 1893, says that he led the world of education by the ways of diligence and thrift, plainness and strength, 勤儉、質實、剛健の風, three virtues with marks between them [30][31]. A sports magazine of June 1898 praises a Tokyo school known for its 質朴剛健 [32]; in 1902 the rules of the school 閑谷黌 tell pupils to put off softness and luxury and build a 質朴剛健 temper [33]. The history books gave the virtue a hero, in the library's text of them: 竹越与三郎's 二千五百年史 of 1896 praises the 質實剛健 of the regent 北条泰時, and the school histories of 1901 and 1902 make 質樸剛健 and 質朴剛健 the mark of the Kamakura warrior [34][35][36]. A paper of the lower house of the Diet of 1906, in the library's text, says that the plain and strong young men of conscription age come mainly from the provinces [37].
In 1908 an imperial rescript, the 戊申詔書, told the nation after the war with Russia to put away show and turn to substance, 華ヲ去リ實ニ就キ; it does not carry 質實 or 剛健, and the education press glossed it with the four characters [38][39]. A school's charge to its pupils printed in 帝国教育 in April 1909 bids them take the rescript to heart, not drift into frivolity, and always cultivate a 質實剛健 temper [40]. The schools statistics of Nagasaki prefecture for 1915, read in the library's text, say that kendo and judo were added to train pupils' bodies and minds and rouse a 質實剛健 spirit [41]. At 中央大学 in Tokyo the president 奥田義人 gave a graduation address in July 1914 which the editor of the university's law review printed under the title 質実剛健の校風, a school spirit of 質実剛健, and a paper of 2009 in the university's historical bulletin traces the motto to that address [9][42]. It quotes the university historian 土方直史 [9]:
中央大学一〇〇年の歴史のなかで、『質実剛健』の『学風』は創立以来のものでなく、明治四〇年代の後半から昭和三〇年代までの五〇年間の『学風』にすぎなかったのである。
In Chuo University's hundred years, the 質実剛健 tradition is not from the founding; it was the tradition only of the fifty years from the last years of Meiji to the Shōwa 30s (1955–64). By the same account it began with the national aim of the revised ethics textbooks of 1910 [9]. By 土方's account, as 風間 gives it, the motto was fixed as a program of moral instruction for students against the First World War, the Russian Revolution, the 大逆事件, the labor movement and the rise of democracy [9].
The rescript of 1923
In February 1923 an industrial magazine complained that since the people had soaked in the mood of the newly rich, the 質實剛健 national spirit had slackened [43]. On 10 November 1923, ten weeks after the Great Kantō earthquake, the second 山本権兵衛 cabinet issued in the emperor's name the 国民精神作興ニ関スル詔書, the rescript on the promotion of the national spirit [44]. It opens 國家興隆ノ本ハ國民精神ノ剛健ニ在リ, the foundation of the nation's rise lies in the firmness of the national spirit, and asks the nation to [8]:
浮華放縱ヲ斥ケテ質實剛健ニ趨キ輕佻詭激ヲ矯メテ醇厚中正ニ歸シ
reject frivolity and license and turn to 質實剛健; correct levity and extremism and return to sincerity and the mean. The 日本大百科全書 says the cabinet issued it to counter democratic and socialist thought, which had spread after the rice riots of 1918, and that after a national federation of moral-education societies was formed in January 1924, 国体明徴 was preached on the rescript's authority [44]. The prime minister's notice of the next day, in the transcription a university history of 2009 gives it, blames the economic disorder the European war left and foreign currents of thought at odds with the national condition, tending toward extreme thought [9].
The words were used at once. On 27 November the Minister of Justice, 平沼騏一郎, told the presidents and prosecutors of the courts of appeal that the spirit of 質実剛健 was declining month by month, and that any who persisted in words and acts that disturbed the social order were to be dealt with as the law commanded, as ja.wikisource transcribes his instruction [45][46]. A commentary on the rescript of 1924, by 亘理章三郎, calls the earthquake, in the library's text, nature's great warning against the frivolity and license of the age [47]. He also wrote, of the rescript's two vices [48]:
若し愼重に意を用ひないで、他を評するに、浮華放縱、輕佻詭激などいふ語を以つてすることがあるならば、それをこそ浮華放縱であり、輕佻詭激であると、非難せねばならぬことゝもなるであらう。
If, without great care, one uses such words as frivolity and license, levity and extremism, to judge others, it may come to be that that very thing must be condemned as frivolity and license, levity and extremism. We should ask first, he goes on, whether we are not so ourselves [48].
To 1945
On 20 January 1931 the Ministry of Education made kendo and judo compulsory for boys in the middle schools, and its instruction gave the reason [10]:
劍道及柔道ガ我ガ國固有ノ武道ニシテ質實剛健ナル國民精神ヲ涵養シ心身ヲ鍛錬スルニ適切ナルヲ認メタルガ爲
because it recognized that kendo and judo are the martial ways native to our country and are fitted to nourish a 質實剛健 national spirit and to train body and mind. A school judo syllabus of 1938 lists 質實剛健 among its lecture topics, in the library's text [49]. In 1932 the ministry's student bureau sorted the writing in middle-school magazines by the tendency of the pupils' thought, with 質實剛健 as one of its classes, and in 1934 it printed the platforms of nationalist student groups, which vowed to raise a 質實剛健 school spirit; both are read in the library's text [50][51]. The Toyoda Precepts, which Toyota's company history dates to 30 October 1935, include 「一、華美を戒め、質実剛健たるべし」, guard against show, and be 質実剛健 [52]. On 22 May 1939 a rescript to the nation's students bade them 文ヲ修メ武ヲ練リ質實剛健ノ氣風ヲ振勵シ, cultivate letters, train in arms, and rouse a 質實剛健 spirit [11][53]. A national policy of 1940 set a 質実剛健 standard of national life fit to endure ten years of hardship [54]. On 8 January 1941 the army minister 東条英機 issued the field service code, 戰陣訓, and its ninth precept is the four characters [55][12]:
第九 質實剛健 質實以て陣中の起居を律し、剛健なる士風を作興し、旺盛なる志氣を振起すべし、陣中の生活は簡素ならざるべからず、不自由は常なるを思ひ、每事節約に努むべし、奢侈は勇猛の精神を蝕むものなり。
Ninth, 質實剛健. Let plainness rule your conduct in camp; raise a firm and vigorous soldierly spirit and rouse high morale. Life in the field must be simple; take hardship as the normal state and be sparing in everything. Luxury eats away the spirit of valor. The precept before it, the eighth, is the one that tells the soldier not to live to suffer the shame of capture [12].
The reading
The Meiji reading of the run is しつじつがうけん, the old spelling of the modern しつじつごうけん: a book of 1908 prints it as ruby on the four characters, of warriors who lost their 質實剛健 temper in the peace of Genroku [56]. The modern dictionaries head it しつじつ‐ごうけん [1].
Today
In 1949 三島由紀夫's 仮面の告白 remembered the years before the war [1][57]:
当時すでに軍人向教育が私の学校をも侵蝕し、名高い江木将軍の「質実剛健」の遺訓が蒸し返されて、派手なマフラーや靴下は禁じられていた
By then military-style education had eaten into my school too; the famous General Egi's precept of 質実剛健 had been dug up again, and showy mufflers and socks were forbidden. In 1969 有吉佐和子 wrote of a nostalgia for the long-forgotten virtue called 質実剛健 [1]. Schools keep the four characters as a motto: CiNii Research indexes, among others, a high school in Wakayama whose motto is 質実剛健 至誠 創造 [58], and the ja.wikipedia article on the phrase lists schools, universities and a police and self-defense-force school that keep it, each at its own site [59]. The デジタル大辞泉's example is a school spirit [1].
In English
The phrase came into English in halves. Kenkyusha's New Japanese-English Dictionary, in its American edition of 1942, has no entry for 質実 or 質実剛健; it glosses 剛健 Fortitude and vigour (robustness); sturdiness; manliness; virility; grit, and under 生命, life, it prints two examples one after the other [13]:
操は女の生命である. Chastity is the life and soul of a woman. ¶ 質朴剛健は本校の生命である. Simplicity and manliness are the soul of this school.
The English monthly Tokyo Gazette gave the ninth precept of the field code in April 1941 as Simplicity and Fortitude. Let simplicity guide your daily life on the battlefield, as the Internet Archive's full-text highlights give it [60]. Nelson's character dictionary, in its edition of 1974, enters 質実剛健, romanized shitsujitsu-gōken, as frugal and courageous [14]. JMdict gives unaffected and sincere, with fortitude and vigor; fortitude and vigour is Kenkyusha's 1942 gloss for 剛健 alone [15][13]. The English keeps one half or the other, the frugality or the courage, and Kenkyusha's gave the strength the name manliness.
A reading
I read 質実剛健 as a discipline a person takes on for himself or herself: to want no ornament, to be in earnest, to be strong and to hold.
That is what the four characters say, and what the dictionaries say today. But in nearly every life this history has read, the words were aimed at someone else. 東湖's plain man was set against the city; 蘇峰's Yamato race against the white races; the rescript of 1923 against frivolity and extremism, which the cabinet's notice traced to foreign thought, and the Minister of Justice turned it on speech within the month; the ministry graded schoolboys' thought by it; the field code put it in a soldier's pack. Kenkyusha's English gave it to the school and its opposite to a woman.
The one sentence I found that saw this was written inside a commentary on the rescript itself. 亘理 warned in 1924 that to judge others with the rescript's words was to be guilty of what they named, and that one should ask first whether one was so oneself. That is where I would hang the scroll. Given to a person for the way he or she means to live, 質実剛健 is plain and good, and the schools that keep it keep that sense. Hung as a judgment on others, it is the history told above.
Notes
Not Chinese, as far as searched. The four characters were not found in the instruments named in Two old words; that is a statement about those instruments, not about every Chinese text [17].
Not 藤田東湖's words. 東湖 wrote 質, plain substance; the four characters stand beside his line as the gloss of 1893, and the Mito sentence of 1897 is his biographer's [5][27].
The date 1889. The essay 田舎漢 is read in the book of 1895, whose table of contents dates its first printing to June 1889; the magazine of that month was not read [6].
Not 1911. The ja.wikipedia article on the phrase, read in October 2026, gives the sentence on kendo and judo to an instruction of 1911 [59]. The instruction of 31 July 1911 that let kendo and judo into the course has neither 質實 nor 剛健 in the library's text of it [61]; the sentence is the instruction of 20 January 1931 [10], and the paper the article cites for it dates it 1931 [62].
General Egi. 江木将軍 is the novel's name; no commentary read for this history says whom it stands for.
Earliest is scoped. 1893 is the oldest print of the four characters read at the page for this history; the related form 質樸剛健 is in 蘇峰's essay of 1889 by his book's dating and in a magazine of 1891, and the National Diet Library's full text was searched oldest first [6][24][18].
