The Democratic Party of Japan and Ishin no To (Japan Innovation Party) took to the Internet on Friday seeking an answer to a first key issue facing them ahead of their merger: a new name.

The DPJ, the largest opposition party, and Ishin no To, the third-largest, are set to merge before the end of the month in a bid to regain voter support and build momentum before summer's Upper House elections.

The parties are inviting suggestions for a name through the DPJ website or by fax from Friday through Sunday.
