A funny thing happened on the day of the Tokyo gubernatorial election - CDP politicians suddenly felt compelled to tweet about Utsunomiya, a city famous for gyoza, with the hashtag #宇都宮
You're not supposed to campaign on voting day, so they couldn't encourage Tokyoites to vote for their preferred candidate, Kenji Utsunomiya, who shares his last name with the city.
By coincidence, CDP politicians, including leader Yukio Edano, thought election day was the right time to profess their love of Utsunomiya (the city)'s gyoza. That would not violate election law, obviously.
