Expanded local autonomy and free education until college are part of a series of proposals for constitutional revision that Osaka Ishin no Kai is finalizing in advance of this summer's Upper House election.

But what exactly the party will say about revising Article 9 of the charter — the so-called peace clause — is still under discussion. The final wording is expected to be decided over the next week, and approved at the party's March 26 convention.

Osaka Ishin no Kai, which has seven seats in the chamber including two up for re-election this year, currently has four candidates running.
