Dear Professor Harnad,

  Thank you for your interest and comments in JAIRO and institutional repositories in Japan.
IR has increased at a high speed in the past 5 years under the positive influence of NII's
financial support and the formation of IR communities in Japan. 1 million contents and 0.7
million full-texts are the results of those succesful efforts.

>Congratulations to Japan's JAIRO for harvesting the 700,000 full-texts (out of one million total) self-
archived in Japan's 158 Institutional Repositories since 2007.

  I'v attached an excel file indicating the number of articles submitted and haversted by JAIRO on
a monthly basis during 2009. According to this statistics, total number of researh articles is
27,718 and it consists of 8,307 English papers and 19,411 Japanese ones (incl. other some languages).

  *You can download the same data from

  *It should be noted that year 2009 in JAIRO means Japanese fiscal year from April 2009 to March 2010.
   So I used figures from the period between January to December in 2009 for the comparison below.

  On the other hand, according to ISI Thomson-Reuter's Global Reseach Report Japan (published this June),
total number of English articles published in the journals which are included in the Web of Science is
approximately 75,000. It is next to UK.

  So just comparing the number of papers writen in English in 2009 (8,307 / 75,000), the ratio of self-archive
is about 11.1%. As you expected, it falls within the unmandated average of 5%-20%.
  I think 158 IRs do cover almost all the reseach-intensive universities in Japan. In that sense, this
 comparison using WoS's figure may be relatively reasonable for the rough estimation of the self-archive rate
 on a national level.
  But I don't have any statisitcal data concerning the annual outputs of all the japanese researchers, so it
is difficult to estimate the accurate percentage of the self-archive by academics.
 *Any comments are welcome from Japan.

>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%?

  Judging from the ratio above, our IR communities will have to carry out as many advocacies as possilbe toward academics
now and in the future. I'd think it would be a common task for repository and research communities around the globe.
  As you might know, I hear Hokkaido University (one of top 10 universities in Japan and hosting IR named HUSCAP) is now
considering to adopt a university-wide mandate. If Hokkaido will succeed, it may have a positive impact on universities
and other higer education institutions. At least, I hope so.


>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

  I'm also sorry to hear about such a low registration rate as open access repository in the ROAR. We will try to persuade
IR managers to register their IRs.

>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...
