Congratulations to Japan's JAIRO
http://jairo.nii.ac.jp/en/ for harvesting the 700,000 full-texts (out of one million total) self-archived in Japan's 158 Institutional Repositories since 2007.
To understand what this figure means, however, the fundamental question is whether or not it represents an increase over the worldwide baseline average for spontaneous (i.e. unmandated) self-archiving, which varies between 5-25% of the total annual output of the primary target content of the Open Access movement: the 2.5 million articles per year published in the planet's 25,000 peer-reviewed journals across all disciplines and languages.
Of JAIRO's 700K full-text total, about 110K (15.5%) consisted of journal articles, based on
http://irdb.nii.ac.jp/analysis/index_e.php
From the growth chart (if I have interpreted it correctly), about 75% of 50,000 articles (i.e., 35,000 full-texts) were deposited in 2009. If we can assume that those deposits were all articles published within that same year (or the preceding one), then the question is: What percentage of Japan's (or of those 158 institutions') annual portion of the 2.5 million articles published yearly worldwide do these 35,000 full-texts represent? Does it exceed the worldwide unmandated baseline of 5-25%?
Message-ID: <dummy3700863996_at_invented.ecs.soton.ac.uk>
The reason I raise this question is because absolute figures -- even absolute growth rates across years -- are not meaningful in themselves. They are only meaningful if expressed as the percentage of total annual output. For a single institutional repository, this means the percentage of that institution's annual output of refereed journal articles. For Japan's 158 institutional repositories, it means the percentage of the total annual output of those 158 institutions.
On the conservative assumption that research-active universities publish at least 1000 refereed journal articles per year, the estimate would be that those 35K articles represent at most about 22% of those institutions' annual refereed journal article output, which falls within the global 5-25% unmandated baseline.
The reason I stress this point is that it is important that we do not content ourselves with absolute self-archiving totals and growth rates that look sizeable considered in isolation. The figure to beat is the unmandated baseline of 5-25%, and the only institutions that consistently beat it are those that mandate self-archiving. Their deposit rates jump to 60% and approach 100% within a few years.
There are already 170 self-archiving mandates worldwide registered in ROARMAP -- 96 institutional, 24 departmental and 46 funder mandates -- but alas none yet from Japan. If there are any, it would be very helpful if they would be registered in ROARMAP

Also, although Japan has at least 158 repositories, only 77 of them are registered in ROAR:

It would be very helpful if the rest were registered in ROAR too...
