Our teacher dedicated his life to the study requiring great pains; as to "Koshi-den", at the end of the Bunka era (1804-1818), he began to write the draft, and by the early Bunsei era (1818-1830), about 12 volumes had been completed; however, by that time, he had also gradually gained an insight into the study and understood the teachings of the master of Suzunoya (Norinaga MOTOORI), then he realized that this world was the product of our great gods of Japan, so he decided to suspend "Koshi-den" temporarily, and first explore and read through all the past annotations of the histories of our country as well as those of India and Europe to use new knowledge to his advantage in writing "Koshi-den"; therefore, since the middle of the Bunsei era, he intensly studied foreign literature and culture mainly, and during a period of over 20 years, he completed almost all his works, which he left for us, including "Sekiken Taiko-den" (Japanese Early History); although he was never satisfied with his works, his students, of course, including myself, with a feeling of gratitude, thought that our master had succeeded in completing most his researches and studies, and were concerned about the delay in completing "Koshi-den" and because of our master's age, we repeatedly begged him to restart the writing, then thankfully at about the 10th year of the Tenpo era (1839), he restarted; however, he was requested to write on linguistic methods so he began to write "Goju Ongi" (Pronunciation and Meaning of 50 Kana) and suspended "Koshi-den" again; after a year, he was banished to Akita Province by order of the former bakufu (Japanese feudal government headed by a shogun), fortunately since Akita was his hometown and there were many relatives of his, besides the former load treated him very kindly, they relieved him off poor living, although under those conditions, he had no time to finish the remaining works; he was always concerned about those unfinished works, and after only a few years, he became sick and regrettably died.発音を聞く 例文帳に追加
