九州出兵期毛利氏の交通政策

In July of the 13th year of the Tensho era (1585), Hideyoshi, who had become kampaku, began preparations for the Kyushu campaign, which was planned for the following year. On 10th April of the same year, a shogunate license approved by Toyotomi Hideyoshi was issued to Terumoto Mori. In it Hideyoshi gave instructions regarding the abolition of checkpoints on land and sea, the repair of roads leading to Kyushu, as well as the preparation of the Gozasho (Hideyoshi’s lodgings).
In this context, the problem arose over how to cross the Kanmon Straits in order to move the army from Honshu to Kyushu. So, in July of Tensho 14, Terumoto built the Gozasho in Akamagaseki. And then, in January to March of Tensho 15, with Hideyoshi’s move to Kyushu drawing near, it became increasingly significant to secure traffic routes to Kyushu. As a result, Terumoto prepared the Gozasho not only in Akamagaseki, but also all over the Sanyo Province. Furthermore, he built roads and bridges. This policy led to strengthening territorial control of each region.
