I just missed the USTREAM live netcast, but there were several hundred people gathered in Omiya City in Saitama Prefecture to protest against the Ooi Nuclear Power Plant restart and against Mr. Yukio Edano, whose constituency is Omiya City.
Mr. Edano was Chief Cabinet Secretary in March last year under Prime Minister Kan, and he was the voice and the face of the government and administration dealing with the nuclear accident and radiation contamination (of which he was instrumental in de-emphasizing and diminishing the severity). His refrain of "There is no immediate effect" at his press conferences in those days will be forever remembered by the Japanese people. He is the current Minister of Economy, Trade and Industry.
According to the tweets of people who were watching the USTREAM (IWJ's channel), they even stopped in front of the huge mansion of Edano and protested. Residents of Omiya City were seen receiving the anti-nuke and anti-Edano flyers from the protesters. Way to go, people.
I'm watching the video recorded live. Ordinary people, quietly walking the main street of Omiya City. As they walk and are warmed up, they start to shout very funny slogans. They also have an excellent collection of hand-made signs and banners.
Screenshot of the USTREAM video (recorded live, still available for a little while), organizers of the event and their handmade sign featuring Mr. EdaNO:

Look at the caricature of Mr. Edano in the screenshot below. The words say "Let's immediately un-elect EdaNO! Goodbye Nuclear [Goodbye] EdaNO! Protest Executive Committee". Take a close look at a yellow balloon that's coming out of Mr. EdaNO's behind. It is a "vent":
People are yelling "Usotsuki EdaNO!" (Liar Edano, with emphasis on NO), "Sayonara EdaNO!", "Don't take us for fools!" "Don't lie to us!", "NO, NO, Eh-Dah-NO!, NO, NO, Eh-Dah-NO!" Then, "Edano wa Jiko Bengoshi." "Jiko bengo" is to defend oneself, make excuse for oneself. "Bengoshi" is an attorney. Edano is an attorney.
This man's sign on his back says "He that will lie will become EdaNO!":
Ah...this is fun.
I think this is Mr. Edano's house. It looks like a fortress (just like TEPCO's former chairman Katsumata's house in central Tokyo):
People are shouting, "EdaNO, Yamero! (Resign!), EdaNO, Yamero!" It rhymes. Sort of. They shouted "Resign!" in front of Mr. Edano's district office in the city center.
Well, Mr. EdaNO is extremely unlikely to resign, so he has to be un-elected, come the Lower House election.
