English: (It has been said that the Hojo clan suffered a crushing defeat in the battle, but a recent study shows that the Takeda army also had a number of casualties, hence it is likely that the battle ended in a draw.)
Japanese: （北条の大敗とも言われているが、近年の研究によって実際には武田方にも多くの死傷者が出ており、双方痛みわけであった可能性が指摘されている）。
English: After the Mimasetoge Battle, although Ujimasa resisted Shingen's invasion of Izu and Suruga Provinces, castles in Suruga Province including Kanbara-jo and Fukazawa-jo Castles fell one after another, and also, Ujiyasu, a guardian of Ujimasa, became too sick to stay in the battlefront, and finally in 1570, Suruga Province was merged and virtually owned by Shingen except Kokokuji-jo Castle and a part of southern Sunto County which remained in the hands of the Hojo clan.

Japanese: 天正6年（1578年）、上杉謙信が死去すると、その後継者をめぐって謙信の甥・上杉景勝と氏政の弟で謙信の養子・上杉景虎（北条三郎、名は氏秀と伝わる。しかし氏秀は北条氏繁の弟で江戸城主であり景虎とは別人との説がある）の後継者争いである御館の乱がおこった。
English: During the internal conflict, Ujimasa was engaged in a battle against the Satake and Utsunomiya clans in Shimotsuke Province, and therefore, he sent Ujiteru and Ujikuni to Echigo Province in June for helping his biological younger brother, Kagetora.

Japanese: しかし、隙をついた徳川家に攻め込まれた東海方面の諸城から援軍を求められる状況に佐渡産の金を押さえた景勝から黄金を贈られた。
English: Katsuyori finally switched to Kagekatsu side on the condition of the cession of Numata, Kozuke Province (the Koetsu Alliance).
Japanese: 勝頼は、上野沼田の割譲を条件にした同盟を受け入れて景勝支持に転じた（甲越同盟）。
English: In rivalry with the Koetsu Alliance, Ujimasa built a new alliance with Nobunaga ODA and Ieyasu TOKUGAWA by reversing the Second Koso Alliance, and invaded the territory of the Takeda clan in Suruga from both sides.
Japanese: 甲越同盟に対して氏政は第2次甲相同盟を破棄し、織田信長・徳川家康と同盟を結び駿河の武田領国を挟撃する。
English: In 1580, Ujimasa attacked Katsuyori, which triggered the Battle of Omosu, but the battle ended in a draw.
Japanese: 天正8年（1580年）に勝頼を攻めて重須の合戦が起きたが、勝負はつかなかった。
English: While Katsuyori continued his offense in Kozuke Province and the local samurai of Kozuke and Shimotsuke Provinces switched to the Takeda clan side, Ujimasa was pushed into the inferior position.
Japanese: 更に上野では勝頼の攻勢が続き、上野下野国衆も武田方に転じたため、劣勢に陥っている。
English: To turn the tide, Ujimasa offered a vassalage to Nobunaga ODA who was building up the momentum by forcing Ishiyama Hongan-ji Temple to surrender.
Japanese: このため、この頃、石山本願寺を降伏させて勢いづく織田信長に臣従を申し出ている。
English: As Katsuyori TAKEDA, his opposition also aimed at making peace and an alliance with the Oda clan, the move by Ujimasa to forestall his enemy and formed an alliance before Katsuyori was a sophisticated diplomacy.
Japanese: 敵対した武田勝頼も織田家との和睦・同盟を画策したため、先手を打って同盟を成立した高度な外交と言える。

Japanese: 同年、嫡男の北条氏直に家督を譲って隠居するが、父氏康に倣い、なおも北条家の政治・軍事の実権は掌握した。
English: In March 1582, when Nobutada, a legitimate child of Nobunaga ODA, launched the campaign of conquering the Takeda clan, Ujimasa ordered Ujikuni to gather information from Kozuke Province to compensate the information shortage in Suruga and Izu Provinces, as the information network in those two provinces had been shut down.
Japanese: 天正10年（1582年）2月、織田信長の嫡子の信忠が武田征伐に乗り出すと、駿豆国境間の情報が途絶していたため当初情報の少なかった氏政は氏邦に上野方面から情報収集させた。
