The Battle of Sekigahara

October 21st, 1600 marks one of, nay, arguably THE most important battle in Japanese history. This event led to the eventual end of the Sengoku period, and helped establish the Tokugawa Shogunate, which would forever alter Japanese history and culture – essentially making Japan what it is today.

It was an ideological battle between two of the greatest Daimyos of the time, namely Ishida Mitsunari, leader of the western armies loyal to the child ruler Toyotomi Hideyori; and Tokugawa Ieyasu who would come to unite Japan under his and his family’s rule until the feudal era collapsed in 1868 through the Meiji restoration, and the Emperor assumed a leadership role over Japan.

The battle was fierce and extremely bloody, fraught with drama and betrayal by people who trusted each other. In the course of the battle, some 30,000 soldiers lost their lives in the span of only 6-7hrs. By all accounts, it was the greatest Samurai battle of all time, and determined the fate of Japan for the next 250 years.

The Battle

It was a misty morning on October 21st, 1600, when 160,000 warriors were getting ready to charge headfirst into this decisive battle over the control of Japan. Visibility was still limited to a few feet due to the fog. It was around 8am when it lifted and both sides could finally see their respective positions. A crack and subsequent echo of musket shots shattered the still soon after. The battle had begun.

How did it get to this fateful day?

As the supreme general Toyotomi Hideyoshi lay dying in the summer of 1598, he left quite a legacy, having completed the unification of Japan, which was started by his master, Oda Nobunaga. His only worthy heir was a young boy, still too young to rule, so Hideyoshi commanded five of the country’s top generals to govern Japan as a council until his 5-year-old son, Hideyori, could assume power. The insecurity following Hideyoshi’s death, however, created a power vacuum, and saw the most implacable of the five regents, Tokugawa Ieyasu, eager to usurp power and establish the supremacy of his own family and heirs.

He would have a formidable rival in the form of another commissioner, Ishida Mitsunari.
Gradually over time, Tokugawa tried to seize more and more power which lead to a confrontation from Mitsunari, challenging his power as the most formidable of the regents. This power struggle ripped Japan in two with the result culminating in the greatest samurai battle in history at Sekigahara.

The location of Sekigahara is at the west end of Gifu Prefecture, near the border with Shiga Prefecture. Sekigahara is the bottleneck between West and East Japan. The route through Sekigahara was the only route for large armies to march between Nagoya and Osaka in the past.

So, on Oct, 21st in the year 1600, an 80,000-strong coalition of soldiers under the command of daimyo feudal lords of the western province faced off against an equal number of troops from the east under the command of Ieyasu.
The forces pitted friend against friend and family against family on the plains of Sekigahara, which was a crossroads between the east and the west of Japan.
Contrary to popular belief, it wasn’t just sword-swinging samurai going at each other in deadly one on one combat, however. There were quite a few technologies and strategies employed, ranging from gunners to horse-mounted archers, all the way to foot soldiers.

Aftermath

Ieasu was eventually able to seize control and win the battle, thus allowing him to also seize control of the country. He moved to Tokyo and established the Tokugawa Shogunate. A few years later, in 1603, he was awarded the coveted Shogun title by the Emperor, and became supreme military commander of Japan.

MITSUNARI WAS EVENTUALLY CAPTURED AND MARCHED THROUGH KYOTO AND BEHEADED. TOYOTOMI HIDEYORI, THE REMAINIG HEIR OF HIDEYOSHI, MOUNTED A FINAL REBELLION AND EVENTUALLY COMMITTED SEPPUKU WITHIN THE FLAMES OF OSAKA CASTLE. THIS SEALED THE FATE OF THE TOYOTOMI CLAN AND CONSOLIDATED TOKUGAWA RULE FOR THE NEXT TWO HUNDRED AND FIFTY YEARS.

This lead to a period of calm in Japan after years of previous civil war during the Warring States Period and ushered in the isolation of the Edo period, which would last until the Meiji Emperor took back power in 1868. This was a period of stability, where peace prevailed for over 250 years, and Japan regained its national pride allowing traditional arts, crafts, and customs to flourish.
