The castle of Edo was the most important architecture in the milital class. The Great Hall (designed by Wakasa Koura, 1860) was magnificently and luxuriously. So I recognigs it the typical type in the Edo perion, and cleare the modular co-ordination of this structure. In order to dispose a building in a spacious site, Wakasa Koura had to estimate a rough measure of the building at the centre-to-centre by 6.5 feet (called 1 ken). As to the planning of the interior of the building, however, he did best in making use of the strength of the surface-to-surface dimentional co-ordination. This co-ordination was developed exactly to 0.0001 feet by the solid geometry. (This structural technique was colled kikujitsu.) Carpenters, of course, was not in need of making so exactly. But It must be pointed out that this design constitutes the highest technique at the traditional Japanese architecture.
