You might also want to follow Watabe-san on Twitter to get notified of any new Japanese translations that show up.
NB! If you want to move to the "New World" - and benefit from the awesomeness of Hadoop, without having to re-engineer your existing applications - check out Gluent, my new startup that will make history! ;-)
