The roof ridge direction of Machiya (traditional Japanese merchant`s house) may vary from one settlement to another, and furthermore, there is a tendency for the number of Machiya houses to decrease year by year. Therefore, there is an urgent need for a comprehensive understanding of the situation of Machiya clusters in each region. This study aims to elucidate the remaining overview of Machiya and the distribution of roof ridge orientation and exterior characteristics in the southern part of Mie prefecture and Wakayama prefecture, as part of nationwide survey. Through investigation, the distribution of Machiya in southern part of Mie prefecture and Wakayama prefecture can be found.
