The second and final wave of unified local elections Sunday brought mixed results to candidates trumpeting minority issues, while highlighting systemic shortcomings in reflecting the diverse opinions of the nation's voters.

Rie Saito, a 31-year-old deaf mother of two who ran for Tokyo's Kita Ward Assembly as a Nippon wo Genki ni Suru Kai (Party to Revitalize Japan) candidate, won with 6,630 votes, the most received by any of the 50 candidates.

Saito, who lost her hearing at age 1, is known for having worked as a hitsudan hostess, using writing to communicate with her customers.
