I've made Constitutional Democratic Party of Japan (2017) a redirect to this article. They looked like duplicates, and someone added a reidrect -- so I've removed the content and left the redirect behind. -- Mikeblas ( talk) 22:03, 24 December 2021 (UTC) reply

@ Mikeblas: They are not duplicate. Despite sharing same name and largely overlap in term of membership and ideology, this party described in this article is a different legal entity from the one in 2017, and is also a merger of the 2017 party with another different party in year 2019, and the political leaning also changed as a result of that merger. It is also reflected by them having different wikidata entry representing the two parties as separate, and other Wikipedia editions also spent different articles to describe them separately. See also discussion in Talk:Democratic Party for the People and Talk:Kibō no Tō, which have similar circumstances and have long opened discussions that still haven't been able to reach conclusions.

Well, there's Constitutional Democratic Party (Japan) for the party that was active from 1927 to 1940. And this article, for the party that was active from 2017 to 2020. The article which was previously a redirect at this revision describes an entity that was founded in 2017. Are you sure that is different than the 2017 party that this article describes? They look the same to me because of the timing and the people involved -- both founded by Yukio Edano, for example. -- Mikeblas ( talk) 17:57, 25 April 2022 (UTC) reply

The 2017 CDP was formed from the split of DPJ. Then some other members from DPJ formed another party called DPFP. Then the two parties, CDP and DPFP merged in 2020, forming a new political party CDP with a more "big tent" political orientation, which is the current CDP. But some members from the old DPFP refused to merge as they see the new CDP as still too left-leaning for their taste, and these politicians created a new DPFP also in the year of 2020, with a more moderate political leaning, which is the current DPFP. So there are five different parties in total.

This is reflected in the article with sections like "History", "Leadership", "Election result" all being separated into before and after mergers. C933103 ( talk) 01:26, 26 April 2022 (UTC) reply

Reviving the discussion from the above thread. This page needs to be split into two pages, one for 2017 and one for 2020.

CDP (2017) was formed as a result of a split from DP (2016), while CDP (2020) was formed as a result of a merger between DPFP, SDP and CDP (2017). Both are different entities despite having the same logos, ideologies and leadership.

To compare, Democratic Party (Japan, 1996) and Democratic Party of Japan have their own separate pages despite the similar circumstances. Ken Aeron ( talk) 14:44, 17 December 2023 (UTC) reply

Strong oppose. Two separate,

much smaller, articles makes no sense. The article is already very clear, with references, that the party relaunched in 2020 with the addition of DPP parliamentarians.— Autospark ( talk) 17:22, 17 December 2023 (UTC) reply

Looks like a simply center - left party
