A Japanese independent journalist posted this photo on his tweet. It is an air dose measurement of 0.54 microsievert/hour in front of a junior high school in a village in Fukushima Prefecture, and the village name is Tenei-mura (pronunciation: ten'ei).
Remember that before the Fukushima nuclear accident, the average air dose rate in Fukushima Prefecture was one order of magnitude lower.
Now, why did this particular tweet catch my attention? Well that village was one of the locations where the high school students from the US were sent, as part of the "Kizuna" project by the Japanese and the US government to show support and solidarity with the "victims" of the disaster and to spread the correct information about recovery and decontamination effort by the Japanese government by having young people from the US visit Fukushima.
Remember those high school students, who followed the footsteps of the students from Middle Tennessee State University?
The original meaning of 'Kizuna' is "a tie that binds a domestic animal so that it can't escape".
From Fukushima-net.com (no date, but assumed to be in July 2012; part):
US high school students visit disaster-affected areas, part of "Project to strengthen 'Kizuna'" in Ten'ei
High school students from the US have been visiting places [in Fukushima] including Ten'ei-mura starting July 10, interacting with the locals to support the recovery from the March 11, 2011 disaster.
It is part of the "Project to strengthen Kizuna", which is commissioned by the Ministry of Foreign Affairs and carried out by the Japan International Cooperation Center. Under the project, high school students from the US are visiting the disaster-affected Miyagi, Iwate, Fukushima and Ibaraki Prefectures and observing the progress of the recovery efforts.
In our Prefecture [Fukushima], a council of Ten'ei-mura is organizing the event from July 10 to 13.
110 students and their teachers from 4 US high schools are in [Fukushima]. The students are learning Japanese at their high schools.
On July 12, they are scheduled to visit the local high schools to interact with the Japanese high school students [there], and to be briefed by the village officials on the progress of decontaminating the farm lands in the village.
The aim of this project is to have the US students see the recovery of the disaster-affected area, and have them spread information on the decontamination effort.
The site has a photograph of students wearing "Kizuna" T-shirts and eating "mochi".
Ten'ei-mura is located along the corridor in the middle of Fukushima where the radioactive cloud passed through, between Sukagawa and Shirakawa. Professor Hayakawa's Radiation Contour Map (ver.7) has Ten'ei-mura inside 0.5 microsievert/hour, with a significant chunk of it inside 1 microsievert/hour.
