Japan's far-right populist Sanseito party was one of the biggest winners in the weekend's upper house election, attracting many voters with its “Japanese First" platform that included calling for tougher restrictions on foreigners and the curtailment of gender equality and diversity policies.

Sanseito, a Japanese populist party that draws inspiration from Donald Trump's politics, is gaining support ahead of Sunday's upper house elections, suggesting a notable shift in the country's traditionally centrist landscape.

Hundreds showed up for Japan’s far-right Sanseito party’s rally on Monday (July 21) where supporters celebrated their victory in Tokyo after the fringe far-right party emerged as one of the biggest winners in the country's upper house election.
