Early life and rise

Môri Terumoto was born Môri Kotsumaru. In 1564 at what appears to have been an early manhood ceremony, Kotsumaru took the name Terumoto (Teru coming from the shogun, Ashikaga Yoshiteru) and assumed command. The Môri's traditional rival, the Amako clan, had been destroyed in 1566, and Motonari had left instructions that the clan be content with what it had and forego expansionist adventure. To a greater or lesser extent, Terumoto followed his late grandfather's instructions. Aside from skirmishes on Kyushu and gradual penetration further east, the first years of Terumoto's rule passed quietly. Later in 1570, Mōri Terumoto defeated Amago Katsuhisa at Battle of Nunobeyama, and forced Katsuhisa fled to the island of Oki. When Motonari died in 1571, Terumoto inherited an enormous kingdom that stretched from Buzen on Kyushu to the borders of Harima and Bizen, a powerful navy (at the time Japan's finest), and the support of two gifted uncles Kobayakawa Takakage and Kikkawa Motoharu.

Conflict with Nobunaga

Before death, Mori Motonari had declared himself no friend to Nobunaga, and the young Terumoto openly challenged Nobunaga. It happened that the Môri were to be drawn into war over the Ishiyama Hongan-ji War, a religious stronghold in Settsu, Nobunaga had been besieging since 1570.

Terumoto turned to the vaunted Môri navy. In 1576, First Battle of Kizugawaguchi Nobunaga's 'admiral', Kuki Yoshitaka, had cut the Honganji's sea-lanes and sat in blockade off the coast. Terumoto ordered his fleet, commanded by Murakami Takeyoshi, to make for the waters off Settsu and, once there, the navy inflicted an embarrassing defeat on Kuki and opened the Honganji's supply lines.

In 1578 Hideyoshi captured Kozuki Castle in Harima and gave it to Amago Katsuhisa, who, supported by the famed Yamanaka Shikanosuke, hoped to restore the defunct Amago clan to power in Izumo. Perhaps goaded by the mere name of the new defender of Kozuki as much as anything else, Terumoto sent his uncles to laid Siege of Kōzuki Castle. This they did, and both Katsuhisa and Shikanosuke were killed. Later in 1578, Second Battle of Kizugawaguchi, Kûki Yoshitaka defeat Takeyoshi and drove the Môri away. A further attempt by the Môri to break the blockade the following year was turned back, and in 1580 the Honganji surrendered.

After Hongan-ji surrender, this allowed Nobunaga to concentrate on the Môri and he sent two sizable contingents westward into the Chugoku region. Hashiba Hideyoshi was to march along the southern portion of the arm (the Sanyodo) while Akechi Mitsuhide moved into the upper provinces (the Sanindo).

By 1582 a Môri defeat seemed inevitable. Hideyoshi had forced his way into Bitchu province and laid siege to Takamatsu Castle.[1] Shimizu Muneharu (a former Mimura retainer) defended Takamatsu stoutly, but its loss would all but open the way into Bingo and Aki, the Môri homeland. Hideyoshi knew that Takamatsu would be a tough nut to crack and that heavy losses would only benefit the Môri, so he resorted to a stratagem. Diverting the waters of a nearby river, he flooded the castle grounds, making Takamatsu a soggy island. By now Terumoto had brought up a relief force, but hesitated to attack Hideyoshi directly. Shimizu, for his part, responded to an offer by Hideyoshi that would spare the lives of his men, and committed suicide after ordering his men to surrender.

Service Under Hideyoshi

After the death of Nobunaga at Honnoji Incident in 1582, Probably most relieved at Hideyoshi's evident generosity, Terumoto agreed, to make peace and allowing Hideyoshi to speed home and defeat Akechi Mitsuhide before anyone else was the wiser for it. As frustrated as the Môri may have been by their discovery of the truth, they did not break the truce, and in time became Hideyoshi's closest supporters.

In 1583 he became a vassal of Toyotomi Hideyoshi. Terumoto sent the 'Two Rivers' (Kobayakawa and Kikkawa) to lead troops for Hideyoshi in his Invasion of Shikoku (1585)[2] and Kyushu Campaign (1587). He sent ships to assist Hideyoshi in his reduction of the Hojo at Siege of Odawara (1590). When Hideyoshi invasion Korea in 1592, Terumoto himself led a 'division' of troops there, although much of his time seems to have been taken up fighting Korean partisans.

Sekigahara Campaign

Terumoto was a member of the council of Five Elders appointed by Hideyoshi. At the height of his power in late 16th century, Terumoto controlled 1.2 million koku. This means he could mobilize more than 40,000 men to a battle. He sided against Tokugawa Ieyasu as the general commander, but was not present at the Battle of Sekigahara. Terumoto was in Osaka Castle defending Toyotomi Hideyori at the time and surrendered to Ieyasu soon after Sekigahara. Ieyasu reduced Terumoto's domains, leaving him only Nagato and Suō Provinces, worth 369,000 koku in total. Finally, his behavior caused resentment of abundant vassals, and that led him to retire.

He is believed to have been a below-average general on and off the battlefield, having lacked motivation and will. He made little impact in these final years of the Sengoku period, as he often had his subordinates and lesser members of the clan fight instead. It is believed that if he had fought at Sekigahara or brought Hideyori to the battlefield, Ieyasu would have been defeated. However, he managed his domain well and successfully held the Mōri clan together even when his domain was reduced to a third.

He was succeeded by Mōri Hidenari.

He was known as a great patron of Hagi ware pottery.
