This paper aims to study of “Jyoui” on the last days of the Tokugawa Shogunate, based on British records. The shogunate signed the trade agreements with five countries in 1858 (Ansei Commercial Treaties). Since then, Japanese people came to demand to exclude foreigners (“Jyoui”). In 1861, the Tozenji that was a temporary English legation was attacked by Japanese warriors. As a result, the shogunate could not help ordering excluding foreigners from feudal lords. It was the only Choshu clan that obeyed it and attacked foreign ships in 1863. In despite of the fact, the Choshu clan sent five people to England in order to study Western technology at the same year. In this paper, an analysis from point of view of Britain has been made on British records with the aim of clarifying “Jyoui”.
