Just like the MOOCH (now known as Moodle.net), the Moodle Association of Japan HUB [http://hub.moodlejapan.org/] is a repository of courses shared across member organizations,
The Course Sharing Hub is a place for Moodle users to share their Moodle courses. This hub has been made by members of the Moodle Association of Japan (MAJ) and we hope it provides an area for members to share and exchange their courses for the benefit of all.
To install from the hub you just need the block on your site. Currently the site is for Moodle 2.2 and 2.3 only, though there are plans to enable sharing of Moodle 2.4. There are around a dozen shared courses on the site most of which are in Japanese.
I find it a very interesting site for the fact that is supports a very specific learning community but has a more curated feel compared to Moodle.net. Have one of your own Hubs to share? Let us know.
