Edo Castle Honmaru

江戸城本丸

What is the Honmaru?

The Honmaru refers to the central part of a castle, the most important area where the lord resided and conducted political affairs. Even in Edo Castle, the Honmaru was a special place, serving as both the residence of the Tokugawa Shoguns and the nerve center of the shogunate that governed all of Japan.

This area, which now corresponds to the East Garden of the Imperial Palace, was strictly guarded and accessible only to a select few during the Edo period. The Honmaru was truly a symbol of Japan's politics and power.


The Honmaru Goten where the Tokugawa Shogun lived

At the heart of Edo Castle's Honmaru stood the magnificent Honmaru Goten (main keep palace). It was not only the living quarters of the shogun but also a vast complex of buildings where important shogunate meetings and ceremonies were held.

Within the palace were the "Omote" for official duties, the "Naka-oku" which was the shogun's private space, and the "Ooku" where the shogun's family and ladies-in-waiting lived, each operated under strict rules.

Here, successive shoguns commanded daimyo across the country and made numerous decisions that shaped the future of Japan.


A history of repeated fires and reconstructions

Edo Castle's Honmaru was repeatedly struck by major fires. Particularly in the Great Fire of Meireki in 1657, the castle, along with the town of Edo, suffered extensive damage.

Even after that, the Honmaru continued to be maintained as a building symbolizing the shogunate's prestige, repeatedly being destroyed by fire and rebuilt. Daimyo from all over the country were mobilized for the reconstruction work, making it a major undertaking that demonstrated the immense power of the shogunate.

From this history, it is clear that the Honmaru was not merely a living space but a political and economic symbol.


The Honmaru, more important than the Tenshukaku

Many people probably imagine the Tenshukaku (castle tower) when they hear of Edo Castle. However, in reality, the Honmaru Goten was the true center of Edo Castle.

Although the Tenshukaku, which was destroyed in the Great Fire of Meireki, was not rebuilt, the Honmaru Goten continued to be maintained. What was important to the shogunate was not a visually impressive castle tower, but the Honmaru where political affairs were conducted.

For this reason, enormous budgets and personnel were invested in the Honmaru, and it developed into one of Japan's largest wooden architectural complexes.


Walking through the current Honmaru site

Currently, the Honmaru site is open to the public as the East Garden of the Imperial Palace. Although the former palace no longer exists, beautiful lawns and stone walls convey the atmosphere of the past.

Standing on the Honmaru Tenshudai (castle tower base) in particular, you can feel the magnificent scale of Edo Castle. Seasonal flowers and trees are planted around, and the cherry blossoms in spring and autumn foliage attract many people.

This place, where you can stroll while feeling history, is surprisingly quiet and peaceful for being in the heart of Tokyo.


What the Honmaru conveys today

Edo Castle's Honmaru was the political center that governed Japan for approximately 260 years. Although it is now a lush green park, the glory of the Tokugawa shogunate and the history of Japan are etched into its ground.

Visiting the Honmaru is not just about seeing a historical site. There, you can feel the decisions of the shoguns, the efforts of those who supported the shogunate, and the culture and traditions of the Edo period.

When you visit Tokyo, why not take a moment to visit the Honmaru site and reflect on the space that was the stage of history? There, a special time flows that you rarely experience in modern Tokyo.
