Hashimoto stayed in a LDP adviser party, and in the 2nd Mori Cabinet the Minister of Okinawa Development Agency and Minister in charge of administrative reform were appointed. He led the faction for several years. In 2001 he was one of the leading candidates to take office as prime minister but lost in the election of the more popular Prime Minister [[Junichiro Koizumi]].

Hashimoto's faction began to collapse late in 2003 while debating over whether to re-elect Koizumi. In December 2004, Hashimoto stepped down as faction leader when he was found to have accepted a ¥100 million cheque from the Japan Dental Association, and announced that he would not run for re-election in his lower house district.

On [[World Water Day]] (22 March) in 2004, United Nations Secretary-General Kofi Annan established a global advisory board on Water and Sanitation, and appointed Ryutaro Hashimoto as its chairman. Just prior to his death, Hashimoto submitted a letter addressed to "The People of the World" for publication in the book ''Water Voices from Around The World'' (October 2007), which is a book affiliated with the United Nations' decade of water (2005–15).{{citation needed|date=June 2015}} In his letter, he addressed water-related disasters around the world, with an urgent appeal to the United Nations to halve the number of deaths caused by water disasters by 2015. Hashimoto closes this letter by writing: "An old proverb says 'Dripping water wears away the stone.' I humbly suggest, that through steadfast efforts, we can overcome any obstacle our civilization may encounter in the coming decade."{{citation needed|date=June 2015}}
