TOKYO, June 26 (Xinhua) -- Japanese Prime Minister Shinzo Abe on Wednesday said that he is committed to promoting local economies across the nation and maintaining political stability, as well as reforming the country's social security systems.

Abe made the remarks in his address to the nation at the end of a regular Diet session. He said he is resolved to continue to steer the country during the Reiwa era which started last month.

Abe said "Society is rapidly aging and shrinking, and the international situation is undergoing turbulent changes. We should not turn our eyes away from these issues and must lay down the path for Japan in the new era. We have that grave responsibility."

He also talked about the upcoming upper house election, saying "the biggest issue is whether we can push forward the reform toward the new age under stable politics or whether we will slip back to an age of confusion."

The Cabinet decided on Wednesday to hold the upper house election and vote-counting on July 21. Official campaigning will kick off on Thursday of next week.

The ruling Liberal Democratic Party and junior coalition partner Komeito are aiming to win a majority of at least 63 of the 124 seats up for grab.

Meanwhile, the prime minister highlighted Japan's position on the world stage, ahead of this week's G20 summit and other major events.

"I am determined to fulfill the responsibility of the chair so that this will be a summit meeting that elevates the post-war Japanese diplomacy to a new dimension," he said.
