Toyotomi Hideyoshi - Rise To Power

Rise To Power

Around 1557 he returned to Owari Province and joined the Oda clan, now headed by Oda Nobunaga, as a lowly servant. He became one of Nobunaga's sandal-bearers and was present at the Battle of Okehazama in 1560 when Nobunaga defeated Imagawa Yoshimoto to become one of the most powerful warlords in the Sengoku period. According to his biographers, he supervised the repair of Kiyosu Castle, a claim described as "apocryphal", and managed the kitchen. In 1561, Hideyoshi married Nene who was Asano Nagamasa's adopted daughter. He carried out repairs on Sunomata Castle with his younger brother Toyotomi Hidenaga and the bandits Hachisuka Masakatsu and Maeno Nagayasu. Hideyoshi's efforts were well received because Sunomata was in enemy territory. He constructed a fort in Sunomata, according to legend overnight, and discovered a secret route into Mount Inaba after which much of the garrison surrendered.

Hideyoshi was very successful as a negotiator. In 1564 he managed to convince, mostly with liberal bribes, a number of Mino warlords to desert the Saitō clan. Hideyoshi approached many Saitō clan samurai and convinced them to submit to Nobunaga, including the Saitō clan's strategist, Takenaka Shigeharu.

Nobunaga's easy victory at Inabayama Castle in 1567 was largely due to Hideyoshi's efforts, and despite his peasant origins, Hideyoshi became one of Nobunaga's most distinguished generals, eventually taking the name Hashiba Hideyoshi (羽柴 秀吉). The new surname included two characters, one each from Oda's two other right-hand men, Niwa Nagahide and Shibata Katsuie.

Hideyoshi led troops in the Battle of Anegawa in 1570 in which Oda Nobunaga allied with future rival Tokugawa Ieyasu (who would eventually displace Hideyoshi's son and rule Japan) to lay siege to two fortresses of the Azai and Asakura clans. In 1573, after victorious campaigns against the Azai and Asakura, Nobunaga appointed Hideyoshi daimyo of three districts in the northern part of Ōmi Province. Initially based at the former Azai headquarters in Odani, Hideyoshi moved to Kunitomo, and renamed the city Nagahama in tribute to Nobunaga. Hideyoshi later moved to the port at Imahama on Lake Biwa. From there he began work on Imahama Castle and took control of the nearby Kunitomo firearms factory that had been established some years previously by the Azai and Asakura. Under Hideyoshi's administration the factory's output of firearms increased dramatically. Nobunaga sent Hideyoshi to Himeji Castle to conquer Chūgoku region in 1576.

After the assassinations at Honnō-ji of Oda Nobunaga and his eldest son Nobutada in 1582 at the hands of Akechi Mitsuhide, Hideyoshi defeated Akechi at the Battle of Yamazaki.

At a meeting at Kiyosu to decide on a successor to Nobunaga, Hideyoshi cast aside the apparent candidate, Oda Nobutaka and his advocate, Oda clan's chief general, Shibata Katsuie, by supporting Nobutada's young son, Oda Hidenobu. Having won the support of the other two Oda elders, Niwa Nagahide and Ikeda Tsuneoki, Hideyoshi established Hidenobu's position, as well as his own influence in the Oda clan. Tension quickly escalated between Hideyoshi and Katsuie, and at the Battle of Shizugatake in the following year, Hideyoshi destroyed Katsuie's forces and thus consolidated his own power, absorbing most of the Oda clan into his control.

In 1583, Hideyoshi began construction of Osaka Castle. Built on the site of the temple Ishiyama Hongan-ji destroyed by Nobunaga, the castle would become the last stronghold of the Toyotomi clan after Hideyoshi's death.

Nobunaga's other son, Oda Nobukatsu, remained hostile to Hideyoshi. He allied himself with Tokugawa Ieyasu, and the two sides fought at the inconclusive Battle of Komaki and Nagakute. It ultimately resulted in a stalemate, although Hideyoshi's forces were delivered a heavy blow. Finally, Hideyoshi made peace with Nobukatsu, ending the pretext for war between the Tokugawa and Hashiba clans. Hideyoshi sent Tokugawa Ieyasu his younger sister Asahi no kata and mother Ōmandokoro (大政所) as hostages. Ieyasu eventually agreed to become a vassal of Hideyoshi.
