Nagoya castle town carrying out the square street project is a feudal city, formed up character at the Edo Period. The author is trying to see the city with a view to study the street projects from three different angles; (1) a study of the linear measure, (2) a few comments on the restoration of the street project, (3) an examination of genealogy concerning the project.
The question resolves roughly itself into the following three points:
A) The checkered-pattern street project in Nagoya was planned out to construct “the measure of one square street project is, 1 Chô (about 109m), extending over East-West 11 Chô (about 1, 199m) × South-North 8 Chô (about 872m)”. Home-lots-division-form in the one square street project adapts a plan of classified three-zone and fistulous type (see. fig.7). Type of this home-lots-division is no better than that of Edo (Tokyo). The length of Edo (Tokyo) street-project is 40 jô (about 118m), however, the feature marks Edo far off from Nagoya and Osaka castle towns.
B) In any city or time, it is absolutely necessary for a would-be fine city to plan the project. The checkered-pattern in Nagoya street-project was performed in due regard to the designs of castle enclosure and unification. There is nothing to choose between the relation of castle enclosure and unification, and the other castle towns in the other cities.
In Nagoya castle town, the place and the width of castle enclosure were the first to provide the position where is the area of northern extremity land on a plateau. Street project run parallel, to the castle enclosure, as well as the pattern of the checkered-street project, descends slowly toward N5°W on the hill (See. fig.8). Geographically this is caused by an use of ground.
C) As the checkered-pattern street project in Nagoya castle town had 1 Chô (sixty Ken, about 109m) which bears a close resemblance to Jôri System, length considered, it is different from Heijô kyo and Heian Kyo which are adopted the cities of older checkered project street. In this Nagoya city, of course, it does not come under the notice of history. The checkered-pattern street project in Nagoya castle town was decided upon the Japanese feet, however, followed another's castle towns which were utilized allotments of grounds for the Jôri System.
As mentioned above, though the pattern is just as Kyoto arranged the older ancient checkered-street projects in order, the unit of the length is based upon the Jôri System.
