Party for Japanese Kokoro

The Nippon no Kokoro Party (Japanese 日本のこころ, roughly "Japan's Heart", English The Party for Japanese Kokoro) was a political party in Japan.

It was founded in the summer of 2014 as Jisedai no Tō (次世代の党, The Party for Future Generations) by a group of MPs led by Shintarō Ishihara when the former Nippon Ishin no Kai split, and formally dissolved and re-formed under Tōru Hashimoto. At its founding, the Jisedai no Tō had 22 members in the national parliament, 19 in the lower house, three in the upper house; making it the third largest opposition party. The Lower House faction, which already had the same name, was formed in early July 2014, and the party formally on August 1. Party chairman (tōshu) was Takeo Hiranuma, secretary-general Hiroshi Yamada, the general assembly of deputies of both chambers was led by Nariaki Nakayama, the upper house deputies by Kyōko Nakayama, Ishihara was "senior advisor" (saikō komon) in the party executive committee.

Even though it was called the "Party of the Next Generation[s]," at its founding the average age of its deputies was 57 and that of several leading members was at least 70. Upper House member Katsuhiko Eguchi, who resigned from Minna no Tō in July 2014, joined Jisedai no Tō a few weeks after the party's founding.

In the 2014 Lower House election, all MPs except Takeo Hiranuma (Okayama 3) and Hiroyuki Sonoda (Kumamoto 4) were voted out. Both left the party in 2015 and returned to the LDP. In the Upper House, four MPs joined and three left since the party's formation until the end of 2015. In December 2015, the party renamed itself Nippon no kokoro o taisetsu ni suru tō (日本のこころを大切にする党, roughly "Party that cares about the heart of Japan", English The Party for Japanese Kokoro). Two months before the 2016 Upper House election, Kazuyuki Hamada resigned. The election left Kokoro without a seat, but it did not lose one either, as no member was up for re-election. Masamune Wada left the party in November 2016.

In January 2017, the two remaining members formed a joint upper house group with the Liberal Democrat Party. It adopted its current name in February 2017.

Chairwoman Kyōko Nakayama left the party in September 2017 and joined the Kibō no Tō. Masashi Nakano consequently took over all high party offices as the only remaining member of parliament.

In October 2018, Nakano announced his return to the LDP, and the party merged into the LDP on November 1, 2018.
