Takeda Shingen

During an invasion of Kai by forces from Suruga, Lady Ōi took refuge at Yōgaiyama Castle and gave birth to Nobutora's heir Harunobu, later Shingen, on the third day of the eleventh month. His birthplace is traditionally identified as either the castle or Sekisuiji at its foot.

Takeda Harunobu sent his father Nobutora into retirement in Suruga and succeeded to the Takeda headship and rule of Kai.

Takeda Harunobu invaded Suwa District in Shinano, forced Suwa Yorishige to submit, and advanced his control of the region.

Takeda Harunobu advanced into Ina District and attacked Fukuyo Castle, defended by Fujisawa Yorichika and his allies, who resisted for more than fifty days.

Takeda Harunobu enacted the Kōshū Hattō, a domain law code governing retainers and territorial administration.

Takeda Harunobu was defeated by Murakami Yoshikiyo at Uedahara and lost senior retainers including Itagaki Nobukata and Amari Torayasu.

Takeda Harunobu attacked Toishi Castle, held by Murakami Yoshikiyo's side, but failed to capture it and withdrew after suffering heavy losses.

Takeda Harunobu and Nagao Kagetora confronted each other at Kawanakajima over control of northern Shinano.

The Takeda, Hōjō, and Imagawa established an alliance through marriages among their children.

Takeda Harunobu and Nagao Kagetora faced each other across the Sai River for a long time and came to terms through Imagawa Yoshimoto. No decisive battle was fought.

After the Takeda took Katsurayama Castle, Nagao Kagetora marched into northern Shinano, but the Takeda avoided a decisive engagement and nothing was settled.

Takeda Shingen strengthens forces near Kawanakajima, restraining Uesugi-aligned kokujin mobilization.

Takeda Shingen and Uesugi Masatora met head-on at Hachimanbara and both sides suffered heavily. Nothing was decided, and the hold on northern Shinano did not change.

The actions of major daimyo such as Uesugi Kenshin and Takeda Shingen were seen as affecting the situation in Kinai. Both Nobunaga and Yoshiaki sought opportunities for broader alliances.

Takeda Shingen launched a full-scale advance toward Totomi and Mikawa, putting strong pressure on Tokugawa Ieyasu's territory and drawing attention as the coalition's most formidable military action.

Takeda Shingen advanced into Totomi and placed strong pressure on Tokugawa castles. Anxiety spread within the Tokugawa camp, and the balance in Tokai became sharply more tense.

Takeda forces captured Futamata Castle in Totomi, breaking through part of the Tokugawa defensive line. Ieyasu was driven into a situation where he had to endure from Hamamatsu and wait for a chance to counterattack.

Takeda forces clashed with the Tokugawa-Oda allied army at Mikatagahara in Totomi, and Ieyasu suffered a devastating defeat. Takeda Shingen's military prestige was displayed to the whole country and gave the anti-Nobunaga side a major psychological boost.
