AFTER the Mongol invasion of Kyushu, Japan held no intercourse with the outer world for several decades, nor does her friendship seem to have been sought by any oversea nation. In the closing year of the thirteenth century, merchantmen flying the Yuan flag are reported to have arrived, but the record is nebulous, and the same may be said of a passing reference that, in 1341, Japanese vessels were sent to China to procure articles manufactured there. We reach more solid ground a year later (1342), when the Ashikaga chief, Takauji, being engaged in building the temple Tenryu-ji, opened trade with China for the purpose of obtaining apparatus, vestments, and works of art. The number of vessels was limited to two annually, and the trade must not exceed five hundred kwan-mon (£750, or $3700). Some of the objects then carried to Japan survive to this day in the form of celadon vases known in Japan as Tenryuji-seiji.* Meanwhile, not a few Buddhist priests crossed the sea from China to preach their faith, and it is certain that during the War of the Dynasties in Japan, when the south of the country was in a state of anarchy, privateering in Korean waters was freely resorted to by Japanese adventurers. A Korean envoy arrived at Fukuhara, in Settsu, in 1367, bearer of a strong protest against this marauding, and declaring that for a decade past assassination and plunder had been freely practised by Japanese subjects on the inhabitants of the Korean littoral. China and Korea were then in a troubled condition.

*The merchantmen received the name of Tenryuji-bune (bune signifies "ship")

In the year (1368) after the arrival of this envoy, the Yuan dynasty went down in China before the Ming, and in Korea the kingdom of Koma was overthrown, the Yi dynasty rising on its ruins and calling the peninsula Chosen. The Ming sovereign immediately attempted to establish tradal intercourse with Japan, but the negotiations failed, and not until 1392 is there any record of oversea relations. Then, at length, Korea's protest elicited a reply from Japan. The shogun, Yoshimitsu, sent to Chosen a despatch, signifying that piracy had been interdicted, that all captives would be returned, and that he desired to establish friendly relations. It appears that at that time China also suffered from the depredations of Japanese corsairs, for the annals say that she repeatedly remonstrated, and that, in 1401, Yoshimitsu despatched to China an envoy carrying presents and escorting some Chinese subjects who had been cast away on the Japanese coast or carried captive thither. Another record suggests that the Chinese Emperor was perplexed between the two warring Courts in Japan. At the time of his accession, a body of Mongol fugitives established themselves in Shantung, where they received assistance from some Japanese adventurers. The Ming sovereign opened communications on the subject with Prince Kanenaga, who held Kyushu in the interests of the Southern Court, but the tone of the Chinese monarch was so arrogant that Prince Kanenaga made no reply. Then Taitsu employed a Buddhist priest, but the character of this bonze having been detected, he was thrown into prison.

These things happened in 1380. In the following year Taitsu despatched a duly credited envoy who used menacing language and was sent back with a defiance from Prince Kanenaga. The priest, however, was set free in 1382, and having learned while in Japan that two Courts were disputing the title to the Crown, he informed the Chinese sovereign in that sense, and the latter subsequently addressed himself to Kyoto, with the result noted above, namely, that Yoshimitsu opened friendly relations (1401). It was to the Ouchi family of Suwo that the management of intercourse with Chosen was entrusted, the latter sending its envoys to Yamaguchi. Subsequently, after Ouchi Yoshihiro's disaffection and disaster, a Buddhist priest and well-known artist, Soami, acted as Muromachi's envoy to the Ming Court, being accompanied by a merchant, Koetomi, who is described as thoroughly conversant with Chinese conditions. By these two the first commercial treaty was negotiated. It provided that an envoy should be sent by each of the contracting parties in every period of ten years, the suite of this envoy to be limited to two hundred, and any ship carrying arms to be regarded as a pirate.

The first envoy from the Ming Court under this treaty was met by Yoshimitsu himself at Hyogo, and being escorted to Kyoto, was hospitably lodged in a hotel there. Instructions were also issued from Muromachi to the officials in Kyushu, peremptorily interdicting piracy and ordering the arrest of any that contravened the veto. Further, the high constables in several provinces were enjoined to encourage trade with China by sending the best products of their localities. In fact, Yoshimitsu showed himself thoroughly earnest in promoting oversea commerce, and a considerable measure of success attended his efforts. Unfortunately, an interruption was caused in 1419, when some seventeen thousand Koreans, Mongolians, and "southern barbarians"—a name given promiscuously to aliens—in 227 ships, bore down on Tsushima one midsummer day and were not driven off until the great families of Kyushu—the Otomo, the Shoni, the Kikuchi, and the Shiba—had joined forces to attack the invaders. The origin of this incident is wrapped in mystery, but probably the prohibition of Japanese pirates was not enforced for the protection of Chosen, and the assault on Tsushima was a desperate attempt at retaliation.

Yoshimochi, however, who was then shogun, seems to have associated China with the invasion, for a Ming envoy, arriving just at the time of the contest, was indignantly refused audience. Thereafter, the tandai appointed from Muroinachi to administer the affairs of Kyushu was driven out by the Shoni family, and the shogun's policy of checking piracy ceased to be enforced, so that the coasts of China and Chosen were much harried, all legitimate commerce being suspended. When Yoshinori became shogun, however, this was one of the directions in which he turned his reforming hand. A Buddhist priest, Doen, proceeded to the Ming Court as Muromachi's delegate, and the Chinese sovereign agreed to restore the old relations, transmitting for that purpose a hundred tallies to be carried by the merchantmen. These tallies were distributed to several high constables, to five great temples, and to merchants in Hyogo and Sakai, the corresponding tallies* being entrusted to the Ouchi family, which, having now recovered its power, was charged with the duty of superintending the trade with China. Meanwhile, So Sadamori of Tsushima had established commercial relations with Chosen, and received from thence a yearly consignment of two hundred koku of soy beans, the vessel that carried the staple being guarded by boats known as Tsushima-bune.

*The tallies were cards on which a line of ideographs were inscribed. The card was then cut along the line, and a moiety was given to the trader, the corresponding moiety being kept by the superintendent.

Thus, it fell out that the right of supervising the trade with China and Korea came into the exclusive possession of the Ouchi and the So, respectively, and being liberally encouraged, brought great wealth to them as well as to other territorial magnates of the central and southern provinces. The records show that large profits were realized. Four or five hundred per cent, is spoken of, and, further, the Ming sovereign, in Yoshimasa's time, responded generously, as has been already shown, to the shogun's appeal for supplies of copper cash. One Japanese fan could be exchanged for a copy of a valuable book, and a sword costing one kwan-mon in Japan fetched five kwan-mon in China. Such prices were paid, however, for rare goods only, notably for Japanese raw silk, fifty catties (sixty-seven lbs.) of which sold for ten kwan-mon (£15, or $75, approximately). Gold, too, was much more valuable in China than in Japan. Ten ryo of the yellow metal could be obtained in Japan for from twenty to thirty kwan-mon and sold in China for 130. Sealskins, swords, spears, pepper, sulphur, fans, lacquer, raw silk, etc. were the chief staples of exports; and velvet, musk, silk fabrics, porcelains, etc., constituted the bulk of the imports. The metropolis being Kyoto, with its population of some 900,000, Hyogo was the most important harbour for the trade, and after it came Hakata,* in Chikuzen; Bonotsu, in Satsuma; Obi, in Hyuga, and Anotsu, in Ise. The customs duties at Hyogo alone are said to have amounted to the equivalent of £15,000, or $75,000, annually.

*Hakata's place was subsequently taken by Hirado.

In China, Ningpo was the chief port. It had a mercantile-marine office and an inn for foreign guests. The tribute levied on the trade was sent thence to Nanking. In size the vessels employed were from 50 to 130 tons, greater dimensions being eschewed through fear of loss. An invoice shows that the goods carried by a ship in 1458 were: sulphur (410,750 lbs.); copper (206,000 lbs.); spears (11); fans (1250); swords (9500); lacquered wares (634 packages), and sapan-wood (141,333 lbs.). During the days of Yoshimasa's shogunate such profits were realized that overtrading took place, and there resulted a temporary cessation. Fifty years later, when Yoshiharu ruled at Muromachi (1529), a Buddhist priest, Zuisa, sent by the shogun to China, and an envoy, Sosetsu, despatched by the Ouchi family, came into collision at Ningpo. It was a mere question of precedence, but in the sequel Zuisa was seized, Ningpo was sacked, and its governor was murdered. The arm of the shogun at that time could not reach the Ouchi family, and a demand for the surrender of Sosetsu was in vain preferred at Muromachi through the medium of the King of Ryukyu. Yoshiharu could only keep silence.
