history Maturity 11-13 Next article →

Heian-kyō was the de jure capital of Japan for over one thousand years. This long period lasted from 794 to 1869.

While Tokyo is the modern capital, some believe Kyoto still holds the official title. Emperor Saga once declared that Heian-kyō would remain the capital forever. The city served as the heart of the Heian period. It was the primary seat of the Imperial Court and imperial power. This made it the most important political center in the country for centuries.

The city was built using a highly organized grid system. This design was modeled after Chang'an, the capital of the Tang dynasty in China.

The city was a large rectangle measuring 4.5 km east to west. It also measured 5.2 km from north to south. The layout followed the principles of geomancy, which is a type of urban planning.

It was designed as a square city based on Chinese astrology. Unlike Chang'an, however, Heian-kyō did not have city walls to surround it.

The city was divided by major streets and minor streets. A massive thoroughfare called Suzaku Avenue ran through the center. This road extended from the palace down through the middle of the city. It divided the city into two distinct sections. The eastern side was called the Left Capital, or Sakyō. The western side was called the Right Capital, or Ukyō.

The Imperial palace, known as the Daidairi, sat at the northern edge. The main palace building, the Daigokuden, was built to be visible from anywhere in the city.

Emperor Kanmu established the capital in 794. He moved the Imperial Court from the nearby city of Nagaoka-kyō.

He chose the site in Yamashiro Province because of its natural features. He noted that the area had beautiful mountains and rivers. The location also offered excellent transport links by both sea and land. This allowed people to gather easily from all corners of the country. The construction began with the palace, and the rest of the city followed.

To support a growing population, the city used several organized systems. Two large markets, the East Market and the West Market, provided food and goods.

Goods arrived at ports like Yodonotsu and along the nearby rivers. These ports acted as transit bases for the entire country. To prevent flooding, workers dug two artificial canals. These canals were the Horikawa and Nishi Horikawa. They provided a steady water supply and protected residents from natural disasters.

Life in the city changed as political power shifted. In 1185, the Minamoto clan defeated the Taira clan in the Genpei War. This moved national administration to Kamakura. Even so, Heian-kyō remained the official capital and home of the Emperor. Over time, the city faced many challenges. During the Ōnin War, almost half of the city was burned to the ground.

The city eventually split into upper and lower sections before being reunited later.

Heian-kyō's legacy continues in modern Kyoto. During the Meiji Revolution, Edo was renamed Tokyo and became the new capital. However, Heian-kyō served as a backup capital when the emperor visited Tokyo. Today, the imperial residences are carefully preserved. The location of the special throne remains at the palace in Kyoto. This throne traditionally marks the seat of the emperor. The history of this grand city remains deeply connected to the identity of Japan.
