順風満帆 junpū manpan Smooth Sailing
Abstract
順風満帆, junpū manpan, is Japanese, fair wind, full sail: the medieval proverb 順風に帆を上げる pressed into four characters, literal in ships' logs from 1873 and figurative in kanbun by 1880, a business-history cliché by the 1930s, and in the 広辞苑 only from 1983. The Chinese say the wish the other way round, 一帆風順. Its neighbor, the Chinese 一路順風, a fair wind the whole way, is the same wind put to other uses: said of a journey that went well, wished at a parting, and used of any course that goes smoothly.
A reading
順風満帆 is the wish for the voyage, fair wind, full sail, Japanese, a sailor's log entry in its oldest dated witness, before any dated metaphor, and the Chinese say the wish the other way round. The first figurative use found is its best reading: the Confucian 土井聱牙, by 1880, tells his schoolboys that once they have come in by the four gates he sets them and the whole library is open, it is fair wind, full sail: the wind and the full sail are what reading feels like then, a joy that comes after the work. Its Chinese neighbor, 一路順風, is a word about the whole road, reported after a journey or wished before it, and a figure for any smooth course besides: the two are one wind seen twice.
Overview
The sense. Fair wind, full sail: the medieval proverb 順風に帆を上げる pressed into four characters. Oldest witness 1873, a warship's log printed in the government gazette. In the dictionaries from 1983 [1]. The same fair wind appears in the Chinese 一路順風, a fair wind the whole way, said of a journey that went well, wished at a parting and used of any smooth course, which has its own history: one wind seen twice.
The words. 順風, the wind that blows the way you are going, is in the 続日本紀 for the year 700 and in the 史記's like shouting with the wind [2]. 満帆 is a sail filled to the full [2]. Both readings of 順風満帆 are old in print: a who's-who of 1917 glosses it じゆんふうまんほ, reading 帆 as ほ [3], and the dictionary's 1929 citation glosses it ジュンプウマンパン [1]. The dictionaries now rule manpan and call manpo wrong; in a 1980 NHK survey of informed people about five in ten answered manpan and three in ten manpo [1], and the open Japanese-English dictionary, JMdict, gives both [4].
The text in English. The open Japanese-English dictionary, JMdict, glosses 順風満帆 smooth sailing [4].
The historical record
To 1880: the Japanese word. 順風満帆 is not Chinese. At Wikisource the only Chinese text with the four characters in sequence is one line of a Qing poet, the fair wind fills the sail's breadth, where the phrase breaks across the words; the Chinese idiom for the wish is 一帆風順, one sail, fair wind [5]. In Japan its dated record begins in ships' logs, meaning exactly what it says. The log of the warship 筑波, carrying Japan's ambassador to China, printed in the government gazette: on 15 April 1873, off Shandong, at 1:45 p.m. weighed anchor, fair wind, full sail; at 7:35 reached Chefoo and anchored. It is the oldest dated witness the National Diet Library's full-text search finds; the Library dates the volume 1876, the year the gazette closed [6]. A manuscript log, the day after its entry names Alcatraz on leaving port: morning southwest wind, afternoon northwest; fair wind, full sail spread; in the forenoon the wind unsettled and the ship rolled hard; in the afternoon she steadied, and went like an arrow [7]. A general's Pacific crossing, on Sunday 18 January 1885 (the diary heads 1 January 明治十八年), printed in 1886: fair wind, full sail, as yesterday; this day ran 244 ri, the diary's sea miles, since it gives the crossing as 4,600 海里 and then as 4,800 里 [8]. The figure is first found in kanbun, in the Tsu Confucian 土井聱牙 (1817–1880), who led an edition of the 資治通鑑 into print, in a charge to his schoolboys: once they have come in by the four gates he sets them, the 通鑑 for history, the 左傳 for the classics, the Su family for prose and 韓非 for the philosophers, and have read and reread until they can range over the whole library taking up whatever comes to hand, it is fair wind, full sail; the height of delight, the height of joy; those who know it know it, and those who do not, do not. His collected prose printed it in 1888 and again in 1892 [9]. Then in prose from 1894: a book an Okayama school published that year, filled with fair wind and full sail, a sick man's letter of 1898, saying that a full recovery is not far off if he guards against a cold, but a fair-wind, full-sail course is not to be counted on, a 1904 book on north China, of Japan under fair wind and full sail, with high hopes for the road ahead, and a 1910 book on imperialism, of the progress of the world economy [10].
1929 to 1983: the cliché and the dictionary. The Library's count of books with the word goes from five in the 1910s to fourteen in the 1920s to ninety-six in the 1930s, and many of the books are company histories and regional who's-whos, where a firm makes a fair-wind, full-sail development [11]. The dictionaries' first citation, a baseball history of 1929, sits in that genre [1]. The four-character dictionary says no pre-war Japanese dictionary (国語辞典) has the word, and none of the 205 books the search finds is a dictionary by its title; the 広辞苑 admitted it in 1983, and the four-character dictionary says it became general only after the war [1]. In print it is more than fifty years older than the dictionary's first citation, and more than a century older than the 広辞苑's entry.
The sense across time. 順風満帆 has two senses: the sailor's plain report, which is where its dated record starts, though the dictionary's citation for it is the later one, 1953; and the figure, the dictionary's second sense, with the earlier citation, 1929. The Japanese word is the proverb's grammar removed: 順風に帆を上げる, to raise sail with a fair wind, whose first citation in the dictionary is the Taiheiki of the late fourteenth century, 順風に帆を揚たれば, is something you do; 順風満帆 is a state you are in [12].
What is not a source. 順風満帆 is not Chinese: the Chinese say 一帆風順 [5]. It is not a proverb with a moral; it is a wish.
Today. 研究社 has In his latter life, he had exceedingly smooth sailing as a financier; the Tanaka corpus of example sentences has he is on a roll [4]. The Kodansha Kanji Dictionary (Halpern 2013), under 帆, gives 順風満帆 smooth sailing, sailing before the wind; JMdict gives sailing before the wind to 一路順風 instead, so the two glosses the open dictionary splits between the two words sit together under the Japanese one there [13].
