Since the 2024 election the party has entered into negotiations to support the LDP-Komeito minority government on a policy-by-policy basis.

[25][26] In January 2018, the DP and the Kibō no Tō agreed to form a joint parliamentary group in both houses of the Diet,[27] although days later the negotiations broke down.

[33] On 19 August 2020, the DPFP announced that a majority of its members would merge in September of that year with the Constitutional Democratic Party of Japan (CDPJ) and some independent lawmakers.

[37][38][39] Party leader Yuichiro Tamaki has been described as "indecisive" on the choice of either joining the government fully or staying in the opposition.

As an example, the DPFP has often times joined in negotiations with the government to raise wages and has often-times attacked other opposition parties, such as the Japanese Communist Party and the CDP at times, but has also proven to be open to cooperation, witnessed in it pulling its candidates shortly before the April by-elections in three House of Representative wards.

[41] Otsuka said that the term "Reformist-Centrist Party" describes the attitude and spirit of the DPP that thoroughly adheres to a democratic approach to realistically reform/solve various issues.

[42] The DPFP defines it as "a reform centrist party led by people ranging from moderate-conservatives and liberals".
