Every year on April 6, Japan celebrates Castle Day Japan, known as Shiro no Hi, a special day dedicated to honoring the magnificent castles built during the samurai era.

In this detailed guide, we will explore Castle Day Japan history, Castle Day Japan facts, and the 10 most beautiful Japanese castles you should explore.
Castle Day Japan History
Castle Day Japan is celebrated on April 6 because the numbers 4 (shi) and 6 (ro) together sound like the Japanese word shiro, which means castle. This clever wordplay led to the creation of Castle Day in Japan to celebrate the country’s historic castles and samurai heritage.
Japanese castles were built mainly during the feudal period, especially in the Sengoku and Edo periods, when warlords and samurai ruled different regions of Japan. These castles were used as military fortresses, government centers, and residences for feudal lords known as daimyo.
Today, many of these castles are preserved as historical sites, museums, and tourist attractions. On Castle Day Japan, many castles host special events, guided tours, cultural programs, and exhibitions.
