The leader of the Japanese Communist Party says Japan should shift from pressure to dialogue in its effort to curb North Korea's nuclear development program.

JCP chief Kazuo Shii, in an interview Monday with The Japan Times, also slammed Prime Minister Shinzo Abe's support for Washington's policy on the North that "all options are on the table."

Abe's "pressure-first" approach toward Pyongyang is one of the key issues the prime minister has stressed in the campaign for next Sunday's general election.
