 note = {application/pdf, 江戸幕府は主要街道を幕府の直接支配下に置き、次第にこの街道が五街道と呼ばれるようになった。さらに五街道から派生する街道のうちのいくつかを道中奉行支配下に置き、幕府支配の道としている。こうした街道を現在研究の便宜上五街道に付属する街道などと呼んでいる。
本稿においては幕府における五街道の意識と五街道という名称および五街道付属街道のうち、水戸佐倉道の性格について考察をしてみた。
五街道の名称は現在広く使用されているが、五街道とは幕府当初から意識されたわけではなく、交通制度を確立していく過程で意識され、五街道という名称もでき上ったものである。幕府が明確に五街道を意識するようになったのは寛文期頃からで、延宝期に至ってより一層五街道意識が確定したとみることができる。また五街道の名称が初めて幕府公文書に表われるのは現在のところ貞享四年（一六八七）に至ってのことである。
五街道に付属する街道はほとんどが起点・終点をみた場合完結している。つまり主要街道間を結んだり、主要地に達している。ところが水戸佐倉道の場合千住から水戸又は佐倉まで道中奉行支配下にはなく、いずれも中途半端な松戸・八幡で道中奉行の支配が終っている。
水戸佐倉道の成立及び支配に関する史料が残っていないため、明確な結論を得ることはできないが、こうした形態は幕府の東国に対する防衛及び、房総半島を近世初期の幕府がどうみていたか、即ち幕府にとって房総の地が重要な要害の地であったことによるものであろう。, The Edo Shogunate had direct control of the main highways, and these roads gradually came to be called the “Five Highways”. Furthermore, several routes deriving from these Five Highways were also under the direct supervision of the Shogunate, under the control of the Dōchū Bugyō (Route Magistrate). At present, these latter roads are, for the convenience of research, called “roads adjunct to the Five Highways”.
In this paper, the author examines the concept of the Five Highways within the Shogunate, the naming of the Five Highways, and the characters of the Mito and Sakura Roads, which were roads adjunct to the Five Highways.
At present, the term “the Five Highways” is used extensively; however, it was not recognized as such in the early stages of the Shogunate; the Five Highways came to be recognized, and the name established, during the process of the establishment of the traffic system. It was around the time of the Kanbun ear (1661 to 1673) that the Shogunate became clearly aware of the Five Highways; and it was in the Enpo era (1673 to 1681) that the concept of the Five Highways became more firmly established. It was in the 4th year of Jōkyō (1687) that the name of the Five Highways first appeared in an official document of the Shogunate.
Most roads adjunct to the Five Highways were complete in terms of their starting points and destinations, that is these routes linked the main highways, or reached important places. However, in the case of the Mito and Sakura Roads, the sections from Senju to Mito or Sakura were not under the control of the Route Magistrate. The control of the Route Magistrate terminated at Matsudo and Yawata, respectively, both part way along the route. Though clear-cut conclusion cannot be reached due to the lack of historical documents regarding the establishment and control of the Matsudo and Sakura Roads, roads of this type were the Shogunate's defense against the Tōgoku (eastern part of Japan) and shows how the shogunate of the early modern period looked on the Bōsō Peninsular; in other words, the Bōsō Region was a place of strategic importance to the Shogunate.},
