Mr Abe’s popularity has slumped in recent months following a series of corruption scandals, but his tough stance on the rogue state has gone down well with voters and he is expected to be re-elected.
A key factor in his popularity boost is a shift in policy on North Korea.
Instead of diplomacy, Mr Abe has recently taken a much more hard-line approach, similar to that of President Donald Trump, focussed on sanctions and increased pressure on the regime.
And he is pushing to strengthen Japan’s military as well as changing a 70-year-old constitutional clause which prevents the county from going to war.
At a pre-election rally in Tokyo today, protestors held a banner which read: “Prime Minister Abe, please protect Japan”.
The nation is well within range of North Korea’s current arsenal of nuclear and conventional weapons, and last month terrified residents on the northern island of Hokkaido were awoken by air raid sirens after a test launch by the rogue state blasted overhead.
Following the launch, Mr Abe described Kim Jong-un’s actions as “utterly unacceptable”.
He said: “If North Korea continues to walk this road, there will be no bright future.
“We need to get North Korea to understand that.”
But despot Kim has continued to threaten to use its nuclear arsenal against Japan because of the country’s long-standing alliance with the United States.
A statement released by the rogue state last month said: “Japan is no longer needed to exist near us.”
It went on to say the Japanese islands “should be sunken into the sea”.
But Japan’s options for dealing with the continued threats are severely limited by their constitution – something Mr Abe has pledged to change.
After Japan surrendered to the US at the end of World War 2, its leaders were forced to change the law to prohibit the county from waging war again.
The controversial clause says “the Japanese people forever renounce war as a sovereign right of the nation and the threat or use of force as means of settling international disputes”.
Japan maintains a small military, which exists in a legal grey area, but there is no doubt that deploying it overseas is strictly prohibited.
And Mr Abe has long-campaigned to change the law which would formally recognise the Japanese Self Defence Force.
