Japanese Prime Minister Shinzo Abe and his ruling coalition party are set for a victory at the polls on Sunday. Next, he'll be seeking out a big win in his dealings with other countries — such as trade, according to analysts.

Major post-election priorities would include trade talks with the U.S., as well as tackling the ongoing wartime forced labor dispute with South Korea that has spilled over into trade, they said.

"Abe is looking for a big foreign policy win. He wants to solve one of these long-standing issues, whether it is territorial disputes with Russia, the abductee issue with North Korea, now finding a way out of the U.S.-Japan trade talks with the U.S.-Japan relations intact," said Tobias Harris, senior vice president at advisory company Teneo.

Tackling such major foreign policy issues will be taking up most of Abe's focus going forward, he concluded.

Those talks with the U.S. are going to be first on the agenda for Abe, according to Harris. Both countries are reportedly working on a trade deal which could involve Japan offering American farmers new access to its markets in exchange for Washington reducing tariffs on certain Japanese auto parts.

The U.S. "is going to insist on trying to get some sort of partial deal done that focuses on agriculture, to give (Donald) Trump a political victory heading into 2020," said Harris, referring to the U.S. elections in 2020.

Meanwhile, amid the dispute with Seoul, Abe's tough stance in imposing restrictions on exports of high-tech materials to South Korea — used by its critical tech sector — has been "certainly popular" with his party supporters who hold "a lot of bitter feelings," said Harris.

Tensions with South Korea have rapidly worsened in recent weeks over the treatment of "comfort women" — women forced to work in Japanese wartime brothels — as well as the compensation of South Korean labor during World War II.
