In 1879 he left the Ministry of Finance and wrote editorials and articles for newspapers while working as a translator, eventually launching his own magazine, the liberally aligned "Tokyo Keizai Zasshi" (Tokyo Economics Magazine) modelled on the British "Economist" magazine in the same year.
翌明治12年（1879年）に大蔵省を辞職し、翻訳業を手がけつつ新聞への投書や著述活動を行い、同年にはイギリスの『エコノミスト』誌を範とした『東京経済雑誌』を創刊し、自由主義の立場での論陣を張った。
