Difficulties multiplied, and the Shogun Iyemochi had taken up his residence in the castle of Osaka, after paying a second visit to the Emperor at Kioto, at the end of 1864, so the foreign ministers had to journey thither when they desired to communicate personally with him in his retreat. By this time some of the more powerful among the provincial daimios had fallen away from their allegiance to the Shogun, and had ceased to attend the Court at Yedo or to reside there during the prescribed six months of the year. Satsuma, for instance, did not occupy his yashiki after September 1862, until he paid it a visit in the early seventies, and others among the Yedo mansions of the provincial lords remained unoccupied from that time forward until they were turned to account as Government offices after the Restoration. The Shogun’s entourage lost the pomp and circumstance of state in 1864, with the removal of his retinue to Osaka, and the internecine strife which culminated in the battle of Uyeno in 1868 was entered upon soon afterwards. In 1866, however, while the Shogun’s men were contending for the mastery with the retainers of Choshiu, the Emperor Komei decided to ratify the treaties that the Shogun had made, and thenceforward the relations of the Bakufu with the representatives of Occidental powers were characterised by greater cordiality than had for some time past existed. The British Minister, Sir Harry Parkes, who had succeeded Sir Rutherford Alcock at Yedo, sent Messrs Mitford and Satow to Osaka with a message to the Shogun, and the mission ended with mutual satisfaction; the Shogun wrote to the Emperor at Kioto urging the opening of the port of Kobé-Hiogo to trade as early as practicable. The Emperor Komei finally gave his consent, and even expressed himself at this time as favourably disposed towards the fulfilment of the treaties. The right of native merchants to hire foreign vessels to trade either at the open ports or abroad was established in 1866, and thus Japanese foreign trade was set free from the restrictions which had checked its development.
