Whether to grant permanent foreign residents voting rights for local-level elections and allow married couples to keep their respective surnames have become contentious issues ahead of the July 11 Upper House election.

The ruling Democratic Party of Japan, which advocates the introduction of foreigner suffrage and separate surnames for married couples if desired, faces strong opposition from conservatives in the Liberal Democratic Party and small parties, including its own ruling bloc partner.

Aichi Prefecture voters, however, are puzzled by the conservatives' fervor because the topics have yet to stir national debate.
