I uploaded the photography of Minamata Disease part of the society textbooks for 5th grade and the Nanjing Incident part of ones for 6th grade to ftp://ftp.emmanuelc.dix.asia/inspected_textbooks/2010/ Those textbooks are inspected in 2010 by Ministry of Education, Culture, Sports, Science, and Technology. The inspection of primary school textbooks this time is done in 2014, last year. It would be good to transcript those textbooks with making the album here but now I put the raw data on FTP. And I’ve deleted their EXIF information.
Those pictures mean that primary schools under Japanese public education law teach Minamata Disease and Nanjing Massacre. We, Japanese people are not against teaching the former. And we argue much about the latter. Anyway, all of us learn them. If we blindly believe our textbooks or if we take the inspection for absolute, few on the net would refute Nanjing Massacre.

I deleted that photos from my anonymous FTP site on 26 Nov 2015. I found it problematic on copy rights…
