A new anti-establishment group led by actor-turned-politician Taro Yamamoto made a surprisingly strong showing in the Upper House election Sunday, reflecting a sense of stagnation and growing public frustration with vested interests in the country.

Reiwa Shinsengumi candidates Yasuhiko Funago, 61, who has Lou Gehrig's disease, and 54-year-old Eiko Kimura, who has cerebral palsy, won Diet seats by priority in the group's proportional representation list.

In an unusual twist, Yamamoto, 44, won more votes than any other candidate in the proportional representation segment of the election but was unable to retain his seat in the House of Councilors because the group only won two seats.
