Kämpfer remained at Gamroon, on the Persian Gulf, for near three years, employing his leisure in scientific researches. Leaving that unhealthy station in June, 1688, he proceeded in the fleet along the coasts of Persia and India to Ceylon, and thence by Sumatra to Batavia, where he arrived in September, 1689. Having obtained the appointment of physician to the factory in Japan, he left Batavia in May, 1690, and having touched at Siam, of which he has given an account in his book, on the 22d of September, about noon, he came in sight of the high mountainous country about Nagasaki. As soon as the land was seen, all on board were required, as the usage was, to give up their prayer-books and other books of divinity, as also all the European money they had about them, to the captain, who, having taken a memorandum of them, packed away all these surrendered articles in an old cask, to be hid away from the Japanese, but to be surrendered to the owners on leaving Japan. At sunset, Nagasaki was six or seven leagues distant. At midnight they reached the entrance of the bay, in which they found fifty fathoms of water. This entrance was full of rocks and islands, which obliged them to wait till morning; and then, being becalmed, they fired cannon to notify their arrival. These were heard at the Dutch factory, six miles distant, and in the afternoon four small vessels came out with some persons from the factory, accompanied by swarms of Japanese officers, clerks and soldiers, and the chief interpreter, who, on boarding the ship, demanded all writings and letters, in the hands of whomsoever they might be. They soon left, and the ship followed slowly, making her way by kedging, till by ten at night she dropped anchor within half a league of the city. The next morning she was towed in still further by a fleet of Japanese boats. The harbor was found to be well protected, and completely enclosed by rocks, islands and mountains, on the tops of which were guard-houses, from which those on the look-out, by means of their spy-glasses, detected the ship shortly after she had made the land, and had given notice of her arrival to the authorities. Along the shore several bastions were seen, with palisades painted red, but no cannon; and on the hills several fortifications, screened by cloths, so as to prevent what was in them from being visible.
