Sanseito attacks “silent invasion” of immigrants, gains traction ahead of Upper House vote.
On July 16, vote tallies showed the Sanseito party, led by Sohei Kamiya, gaining momentum in the run-up to Japan’s Upper House elections scheduled for July 20. Riding a wave of nationalist sentiment, the party has criticized what it calls a “silent invasion” of foreign nationals.
Sanseito originated from YouTube livestreams during the COVID‑19 pandemic and has since leveraged social media to spread its message. Polls suggest it may secure 10–15 of the 125 contested seats—a notable performance for a fringe party.
Kamiya asserts the ruling coalition of the LDP and Komeito must address immigration concerns or risk losing support, reflecting broader unease over economic competition and national identity.
Observers caution that even limited electoral success could embolden similar ultra‑nationalist forces across Japan’s political scene, pressuring mainstream policymakers to adopt more rigid immigration stances.
