Also known as: Suwa Katsuyori (諏訪勝頼)

Fourth son of Takeda Shingen. His mother was not Sanjou, but Suwa Goryounin, the daughter of the head of a defeated clan, Suwa Yorishige, Shingen's concubine. He was originally kept out of the line succession to the Takeda clan by being made head of the Suwa Clan. However, when Shingen's heir, Takeda Yoshinobu was found plotting against his father and ordered to commit suicide, Shingen named Katsuyori's son, Nobutatsu, his heir and Katsuyori guardian. Katsuyori took over rule of the Takeda clan when his father died.

Katsuyori was decribed as a brave and exceptionally skilled fighter, but lacking in strategy when he took over the Takeda army. In 1578, during the Otate no Ran, he betrayed his allies the Houjou clan and took Uesugi Kagekatsu's side, thus adding the Houjou to his list of enemies. He was increasing unpopular with the people of Kai due to heavy drafts caused by defeats in battle with the Oda, Tokugawa, and Houjou clans.

In 1582 Kai and Shinano were invaded by the combined arms of Oda, Tokugawa, and Houjou. Most of Katsuyori's troops abandoned him, and he committed suicide.

Tamanawa was a mountain castle built by Houjou Souun in 1513 as a strategic point guarding over the Miura Peninsula and Musashi Province. Its moat ran directly into Kashio River and from there into Sagami Bay, providing a launching point for sea battles.

The castle was reputed to be impregnable; it turned aside a combined force led by Satomi Yoshitoyo and Ashikaga Yoshiaki in 1526 as well as further attacks by the Satomi Clan. Both Uesugi Kenshin and Takeda Shingen gave up on its capture in their forays into Sagami. The last Houjou master of the castle, Houjou Ujikatsu, surrendered to Toyotomi Hideyoshi in the Siege of Odawara.

During the Edo Period, the castle was the stronghold of several trusted retainers of the Tokugawa before finally being abandoned in 1703. A girls' school (<a href="http://izumi.seisen-h.ed.jp/">Seisen Junior and Senior High School</a>) is now located at the castle's former site.
