As far as can be ascertained, Shuri continued to reside in his native town until he was twenty-nine years old, when he set out for Yedo, as the capital of the Shogun,—now Tokio—was then called, to seek his fortune. There he studied diligently, under such celebrated professors as Hayashi Jussai and Sato Issai, the then much-prized Chinese literature, and enjoyed the close friendship of those profound scholars Yanagawa Seigan, Watanabe Kazan, and Tsuboi Shindo. All these men won for themselves enduring fame as exponents of the writings of the Chinese sages, and under their guidance Sakuma became deeply versed in the teachings of Mencius and Confucius, and many of the lesser lights of Chinese philosophy. Japan’s rigid seclusion from the outer world, which had at that time already lasted over two centuries, had had the result, for one thing, of elevating Chinese learning to a position, in the eyes of the average Japanese, scarcely less exalted than that of Greek or Latin in England in the Middle Ages, although in Japan some knowledge of Chinese was found among all classes. But Sakuma’s studies were by no means confined to Chinese literature. He set himself to glean all that he could from the works of the Hollanders, then almost the only Occidental writings available to the Japanese in their search for information, and having acquired a fair knowledge of the Dutch language, he embarked resolutely on an investigation of the arts and sciences of the West, including the manufacture of firearms, the construction of vessels of war, of fortifications, and the casting of heavy guns. The immediate effect of his researches was to imbue his mind with a conviction of the paramount necessity of strengthening the national defences, and providing against the contingency of an attack by some hostile Western power. His studies in musketry led him to invent a new weapon, in the shape of a musket capable of far greater rapidity of fire than that which at the time was in use, the pattern of which had been brought from Europe. Sakuma was groping in the dark, by comparison with those of his fellow-countrymen who, at a later date, followed in his footsteps along the path which led to substantial reforms, but he was on the right track, as his unerring judgment assured him, though it was not his fate to live until the dawn of the Meiji era, still less to be able to form a true conception of the success that would attend his country’s efforts and the phenomenal progress that would be achieved under the beneficent auspices of the Emperor Mutsuhito’s reign. In 1842, which was the thirteenth year of the Tempo period, while the Emperor Ninko was on the throne, the feudal chieftain of Shinano, Sakuma’s native province, was given high office under the Tokugawa Government—that is to say, under the administration at Yedo of the Shogun, or as he was better known to Europeans, the “Tycoon.” The Shinano _dai-mio_, as the feudal chiefs in
