Sanseito’s Rise in Japan Signals Growing Support for Far-Right Politics
Just one day after Japan’s upper house election, supporters of the far-right Sanseito Party gathered in Tokyo to celebrate an unexpected success. Sanseito’s rise, which champions a “Japanese First” approach, saw its seats in the 248-member chamber rise from one to 14.
Growing Popularity Among Young Men
Sanseito’s rise reflects a broader trend of increased backing for right-wing groups in global democracies. In Japan, the party’s message has struck a chord with younger voters, especially men. Yuta Kato, a Tokyo-based hairdresser, is one such supporter. He feels increasingly frustrated by foreign tourists who, in his view, ignore Japan’s social customs. He cites examples like loud videos played on public transport and foot traffic blocked in high-end districts such as Ginza.
Though foreign-born residents account for just 3% of Japan’s population—a far lower share than in the US or Europe—tourism has made their presence more noticeable in urban areas. Many Sanseito followers, including Kato, turn to YouTube and social media for their information. These platforms have helped the party grow by spreading messages warning of a “silent invasion” of foreigners and claiming threats to Japanese traditions.
A Controversial Platform
Sanseito first gained attention during the COVID-19 pandemic by promoting vaccine conspiracy theories. It has since broadened its appeal. The party now supports strict immigration controls and economic relief for families impacted by inflation. It also promotes more radical goals such as discarding Japan’s pacifist constitution and reinstating greater authority to the Emperor. These ideas are shared by fringe nationalist groups often seen in black trucks blasting wartime songs.
Unlike these older movements, Sanseito has embraced digital platforms. Its leaders aim to mirror the achievements of European far-right parties, such as Germany’s AfD and Britain’s Reform UK. While some praise its fresh approach, others express concern.
Rising Influence, Growing Concern
Critics argue that Sanseito is helping to normalise xenophobia in Japan. Though party leader Sohei Kamiya denies such claims, the debate continues. Artist Masayuki Nabekura, who campaigns for anti-racism measures, warns that the party poses a real risk to Japan’s social fabric.
Romeo Marcantuoni, a Tokyo-based academic, says the party plays on various anxieties—from noisy tourists to fears of Chinese political influence. Chinese nationals make up the largest group of foreign residents and visitors in Japan, often becoming targets of anti-immigrant rhetoric online.
Sanseito finds its strongest support among voters aged 18 to 39, especially men, according to NHK polling. In contrast, Prime Minister Shigeru Ishiba’s ruling Liberal Democratic Party garners more support from older generations, particularly those over 70.
Online, Sanseito enjoys strong engagement. Its YouTube channel has three times as many followers as the LDP’s, according to the Asahi newspaper. This digital success has become a vital tool in the party’s strategy.
