The Democratic Party of Japan is having an identity crisis.
Although the largest opposition party adopted a new policy platform at its party convention Sunday, it failed to include any key issues or doctrines that differentiate it from its rivals.
Political observers warn that the party is running the risk of suffering another crushing defeat in the House of Councilors election in July, following December's Lower House poll, in which the party lost 173 of its 230 seats in the chamber.
