The history of Nagoya dates back centuries, yet its destiny as a major city was defined in the early 17th century. Although settlements existed in this area earlier, it was the visionary decision of the Shogun and unifier of Japan, Tokugawa Ieyasu, that marked the beginning of the modern metropolis. In 1610, by his order, the construction of the majestic Nagoya Castle began, intended to be a stronghold of power and a strategic centre. This castle became the heart of the future city, around which life began to thrive.
The construction of the castle was a turning point. To populate the new castle town (jokamachi), a significant portion of the residents were relocated from the neighbouring town of Kiyosu, which had previously been the centre of Owari Province. The choice of location for the new citadel was not accidental: Nagoya occupied a favourable position on the fertile Nobi Plain, exactly halfway between the imperial capital of Kyoto and the political centre of Edo (modern-day Tokyo). This location made the city a key point on the country's main trade route — the Tokaido Road, which contributed to its rapid economic growth.
Nagoya's political status was also exceptionally high. The castle became the residence of one of the three main branches of the ruling Tokugawa clan — the Owari branch. This ensured the city's stability, the patronage of the shogunate, and prosperity for over 250 years during the Edo period. Thanks to this, Nagoya developed not only as a military fortress but also as a bustling centre of crafts and trade. The city quickly became famous for the production of high-quality ceramics and porcelain, as well as textiles. By the mid-19th century, thanks to its strategic and economic importance, Nagoya had become the fourth-largest city in Japan.
