The hatto of Shokokirji reconstructed by Hideyori in 1605 is of the utmost historical importance being the oldest and largest extant example of its type. Despite a shortage of lumber and various problems involving logistics,the building was completed in one year and became the exemplary model of subsequent hatto architecture. Its success as an architectural design lies in the fact that it was both large enough for the performance of religions rituals and rationally determined so that unnecessary elements were eliminated (i.e. it was both functional and economically efficient.)As a result, it came to represent a new kind of internal space.
