Rambelli Fabio Nobody s mentioned this article yet written in Japanese by this guy correct Although not without a fair number of such as and not to mention being somewhat lacking in depth and more so a description of one man s experiences the author s it is nonetheless relatively academic and may be reasonable as a source for the article especially since there seems to be somewhat of a lack of sources actually written in Japanese Just thought I d throw it out there Additionally this article also popped up on google scholar and looked potentially interesting but it looks like I ll have to see if I can get an interlibrary loan in order to access it myself If someone has more immediate access than I do it may be worth looking up
