Continuity in Tokugawa diplomacy : from early to late Edo with a focus on Tokugawa official Tsutusi Masanori and his accumulation of experience

该项目旨在通过将日本后期与西方的江户国际关系置于其在江户时代保持的亚洲之间的关系，特别是韩国关系，来发现德川外交的连续性。德川官员津井正则(1778-1859)作为一位能够代表这种连续性的人物而被特别关注。事实证明，该项目成功地从未经研究的角度描述了连续性，揭示了从筑井开始的一代又一代“开明”的德川官员的现场政策管理经验的积累。整个活动都牢固地建立在对筑井的史学研究的基础上。

This project aimed to discover the continuity in Tokugawa diplomacy, through placing Japan's late Edo international relations with the West upon its inter-Asiatic, in particular Korean, relations maintained over the Edo period. The Tokugawa official Tsutsui Masanori (1778-1859) was particularly focused on as a figure who could represent such continuity. The project has proved to be successful in describing the continuity from an unstudied perspective, by means of shedding light on the accumulation of on-the-spot policy management experiences of "enlightened" Tokugawa officials from generation to generation starting from Tsutsui. The entire activities have been firmly based on the historiographical research concerning Tsutsui.
