Ieyasu Tokugawa’s Reign Over Hamamatsu Castle 1

1. Starting point of Hamamatsu as a pre-modern city

According to the biography of Ieyasu Tokugawa (Butoku-hennen-shusei), it was on July 5th 1569 (the 12 year of the Eiroku era) that Ieyasu renamed the castle “Hamamatsu Castle” and thus established the pre-modern city’s name as “Hamamatsu” too.

It is generally agreed that Ieyasu officially moved to Hamamatsu Castle during the year 1570 (1st year of the Genki era) however some books and literature might say differently. Afterwards, from 1577 – 1582 the construction of Hamamatsu Castle was conducted.

It is thought that Ieyasu steadily expanded the previous Hikuma Castle while taking his time to establish Hamamatsu Castle.
