Japanese government data catalog site, “DATA.GO.JP” was launched on October 1,
2014. It is provided by the Strategic Headquarters for the Promotion of an
Advanced Information and Telecommunications Network Society (IT Strategic
Headquarters) in Cabinet Secretariat.
The Japanese government is promoting the Open Data
initiative, in which the government widely discloses public data in
machine-readable formats and allows secondary use of the public data for
profit-making or other purposes. This initiative has the goals of improving
people's lives and stimulating corporate activities, thereby contributing to
social and economic development of Japan.
This website serves as a catalog of this
Open Data, and is intended to provide information about public data available
for secondary use. The website provides extensive search capabilities.
In this site,
people can search government data from top page. Main contents of this page are
the following:
<Main Contents>
l Data (21 government organization, 12347 datasets)
l Terms of use
l Open Data Initiatives (Policies and Decisions about Open
Data)

PDF format, and second largest format is in HTML which is 33.6%. Most PDF datasets
are documents of government budget and final accounts and procurement, and most

comparison of the government open data format between Japan and USA.

From the perspective of covering a large
volume of data, this site includes past data in non-machine-readable formats.
However, from the perspective of using secondary data, Japanese datasets are
expected to be CSV, XML, and JSON instead of PDF because datasets that have
their data in PDF are not readable and cannot be edited easily.
In statistics page, we can see visitors from other
countries for the current month. Today(2014/10/15), the largest visitors’
country is Japan, second is USA, third is unidentified(!), forth is China.
In
addition, according to Japanese government IT dashboard that provides
statistics information about DATA.GO.JP, 96.9% of data in “DATA.GO.JP” are
provided in Japanese.
Communication
About communication, there are no comments
and feedbacks. One reason is that it has been only 15days since it was launched.
Case of using public data in Japan
<Book search service “Calil”>(Sorry, It has only Japanese page)
This
is the searching service of books across 5,200 libraries in Japan. Using this
service, the users can see the status of the books whether the books are available
or not. Additional information about the book posted on “Amazon.com” and link
to the online bookstore are also displayed in the same page. In case the books
are not available in any libraries, the user can go to online bookstore by
clicking the link displayed.
I
hope that this open government data will be used for creating new services and
new value.
