After living in retirement for 19 years, he served in the Shogunate government under Premier Naosuke Ii again and attended diplomatic affairs. Tadanori Mizuno and Tadanari Iwase were under his control. Trusted by Ii, he concluded at his own discretion provisional treaties with Britain, France, Russia and Holland. He later disagreed with Ii, resigned and lived again in retirement. He again served in the Shogunate government (1863) at its invitation. He resigned in disappointment and died of illness (1867).
