Japanese stocks surged to a record high as markets opened on Monday morning, as Prime Minister Sanae Takaichi's Liberal Democratic Party (LDP) basked in a historic election victory.

The LDP secured 316 out of 465 seats in Sunday's election, the first time a single party has won a two-thirds lower house majority since Japan's parliament was established in its current form in 1947.

The Japan Innovation Party, the LDP's coalition partner, won in 36 more constituencies, taking their combined total to 352 seats.

The resounding mandate is a gamble that paid off for Takaichi, who now faces the challenge of reviving Japan's moribund economy and tackling cost-of-living woes.

The Nikkei index rallied by more than 5% in early trade on Monday, briefly crossing the 57,000 mark for the first time.
