Ujimasa commanded in many battles, consolidating his clan's position, and retired in 1590. His son Hōjō Ujinao became head of the clan and lord of Odawara, but later that year they failed to hold Odawara against the forces of Toyotomi Hideyoshi (see Siege of Odawara (1590)). Ujimasa was forced to commit suicide along with his brother Ujiteru.
- Autumn wind of eve
- Blow away the clouds that mass
- O'er the moon's pure light.
- And the mists that cloud our mind
- Do thou sweep away as well.
(雨雲の おほへる月も 胸の霧も はらひにけりな 秋の夕風)
- Now we disappear
- Well, what must we think of it?
- From the sky we came
- Now we may go back again
- That's at least one point of view.
(我が身今 消ゆとやいかに 思ふべき 空より来たり 空へ帰れば)
(吹きとふく 風な恨みそ 花の春 紅葉も残る 秋あらばこそ)
