I found this poster in Tokyo.
The poster of the photograph says as follows.
'Don't forget many our friends who killed by work exposed to radiation.'
There were many photos of each worker's face at the right side of the poster.
We could burn incense in front of the photos for the soul of the deceased.
A lot of poor people is working for Fukushima Dai-ichi Nuclear Power Plant.
Tokyo Electric Power Company, TEPCO, rarely hire them directly.
A subcontractor hire them.
There are many subcontracting companies between TEPCO and poor workers as the nested structure.
The fee that poor people get is reduced by kickback by many companies, so it's not enough.
The difficulties of knowing the exact data about each worker's radiation exposure dose make it easy to escape responsibility for.
